Motorola-Unipage Paging Terminal

(Source: Motorola, author unknown.)

The Unipage Paging Terminal is uniquely qualified to provide seamless expansion and tremendous versatility for your paging operation. Once you become familiar with the advanced architecture and features of the Unipage, we are confident you will agree that Unipage provides a Terminal platform unparalleled in the paging industry.

Unipage's seamless expansion provides you with the ability to start your system at any size and expand without concern for outgrowing the Unipage architecture. The benefit to you is that no system components, including the CPU, power supply, and housing, are ever discarded.

Furthermore, as we at Motorola develop new, advanced components for the Unipage Terminal, they can simply be added to your current system without the need to purchase an entirely new Terminal.

Along with our ability to expand comes the ability to provide all of the latest features including voice messaging, alphanumeric, and networking capabilities for both small and large systems alike.

The purpose of this document is to provide an overview of what components are needed to make a paging network operate, and to explain the features and advantages of the Unipage Paging Terminal as part of this complete network. Your Motorola Account Executive is available to provide more in-depth information in the areas that you request.

Before discussing the Unipage system, it is important to explain what the Radio Frequency (RF) paging network interfaces with, and how the Terminal fits into this RF paging network. Therefore, what follows is a brief explanation of this interface, and a brief identification and definition of each component in the paging network.

To begin, the RF paging network interfaces with the Public Switched Telephone Network (PSTN), which provides basic telephone service to its customers. The PSTN also provides the dedicated circuits, or "trunking", which interface with the Paging Terminal. The Paging Terminal is the initial entrance into the RF paging network. Therefore, a caller is in essence contacting the Paging Terminal through the PSTN to send a message.

People who are calling from a Private Access Branch Exchange (PABX) or cellular system can also access the RF paging system. However, this access is still accomplished by going through the PSTN (assuming the paging system is not "closed" to public access). Figure 1 provides an illustration of how callers can access the RF paging network via the PSTN.

The following five items represent the components which make up a paging network:

Pager - This device, which is carried by the paging service subscriber, is a radio receiver that receives incoming messages. The information that the pager receives can be either numeric digits or alphanumeric characters.

Radio Frequency (RF) Transmitter - This component converts the paging data coming from the Paging Terminal into an FM radio signal to be broadcast over the air. Typically, radio paging frequencies are located in predetermined bandwidths which generally range from 150 MHz to 900 MHz.

Paging Terminal - This component serves as the interface to the PSTN. The Terminal's primary function is to receive information from the PSTN, manipulate it, and route it to the RF Transmitters for FM broadcast. Information that is coming in from the PSTN can be in numerous formats, including voice, Dual Tone Multi Frequency (DTMF), Multi-Frequency (MF-R1 or MFC-R2), and/or modem tones (input via Video Display Terminal (VDT), Personal Computer (PC), Operator Assisted Paging (OAP) System, or other special input device).

RF Transmitter Controller - Most paging networks utilize multiple RF Transmitters located in one or more cities or regions. Typically, the coverage area of a particular Transmitter overlaps with that of other Transmitters. This overlap can cause reliability problems unless the Transmitters are properly configured.

Reliability problems result when paging signals from different Transmitters do not arrive in an overlap area at the same moment in time. This occurrence causes conflicting radio signals to exist in the same area, which causes part of the signal to be canceled out. The end result is that the pager cannot interpret part of the radio signal being sent to it, so the page is lost.

To avoid this problem, it is necessary to have radio signals from multiple Transmitters arrive in an overlap area at the same time. By arriving at the same time, the signal that the pager receives appears to be originating from a single source. This process of having multiple, identical radio signals arrive in an area at the same time is called "simulcasting."

figure 1


Simulcast paging systems are configured to have each Transmitter broadcast identical paging data at the same time (within a tolerance of microseconds). The component that coordinates this task is the RF Transmitter Controller.

The Controller is co-located with the Paging Terminal. From a system call flow perspective, the Controller is located between the Paging Terminal and the Transmitters it controls. The method used to pass the information to the Transmitters can vary, depending on what method the service provider prefers:

Dedicated Circuit - This setup provides a direct, dedicated telephone circuit between the Controller and each Transmitter in the network. Although this method works, it may not provide the stability required for simulcast systems. Specifically, the circuits' impedance values can change, primarily from environmental conditions such as humidity. Since simulcasting requires the timing for Transmitters to be within several microseconds, these impedance changes can cause the timing for a particular RF Transmitter to be outside of its required parameters.

RF Link Transmitter - This Link Transmitter is similar to the RF Transmitter described previously, but operates at a different frequency and power output. The Link receives the information from the Controller and broadcasts it. All of the RF Transmitters in the system are equipped with Link Receivers which pick up the radio signal and pass it to its respective Transmitter. Each Transmitter rebroadcasts the data on the appropriate paging frequency.

Satellite - The Controller can be connected to a Satellite Link to deliver paging data to the Transmitters. Generally speaking, the Controller is connected to an "uplink" which delivers the paging data to a satellite. This satellite receives the signal and retransmits it back to Earth within a given coverage area, or "foot print". A Transmitter located within the "foot print" receives the signal via Satellite Receiver and rebroadcasts it on the appropriate paging frequency.

Operator Assisted Paging (OAP) System - This system is used when a live operator is needed to input the paging information into the Paging Terminal. Typically an OAP system is used when DTMF telephones are not available to allow for automatic paging. An OAP system is separate from the Paging Terminal and interfaces with it via RS-232 serial port connection. This interface typically uses Telocator Network Paging Protocol (TNPP) or Telocator Alphanumeric Protocol (TAP), which are both industry standard protocols.

figure 2


Larger OAP systems typically have an Automatic Call Distributor (ACD) or PABX on the front-end to receive the incoming calls. An operator obtains the message from the caller and inputs it into the OAP system. This OAP system then passes the information to the Paging Terminal. The message being sent to the pager is typically alphanumeric.

Now that all of the components have been identified and defined, Figure 2 illustrates how each fits into a total RF paging network.

The key to the Unipage system's seamless expansion and versatility is its "modular" architecture. The method used to expand an existing Unipage Terminal is simply to add more "modules" to the equipment already in place.

Specifically, the Unipage Paging Terminal is based on a 15-slot rackmounted chassis with its own built-in power supply. This chassis houses the various card components such as trunk input and channel output cards that perform the required paging tasks. When integrated with two other vital system components, these 15 slot chassis provide full paging and voice messaging functionality in a fully integrated system.

A Unipage system can consist of the three components described below:

The Paging Terminal is the primary component of the system and consists of one 15-slot chassis, or multiple 15-slot chassis configured together. The Paging Terminal provides the interface between the PSTN and the RF Paging Network. Specifically, it handles all telephone trunk inputs, alphanumeric serial port inputs, TNPP serial I/O ports, and all paging outputs to one or more RF paging channels.

The Console Computer with Unipage Operating Software is a required component which works in conjunction with the Paging Terminal. The Console provides the mechanism to manipulate and review all system data contained in the Paging Terminal and the Message Manager™. The Console's functions include pager and voice mailbox programming, database maintenance, system parameter setting, report generation capabilities, and "real time" system status.

The Message Manager™ is an optional component which, if included, is fully integrated into the Paging Terminal. The Message Manager™ provides custom voice prompts and full-featured voice messaging services, including Alpha Transcription.

The Message Manager™ is fully integrated because it utilizes the Unipage Terminal's "X-bus". The "X-bus" serves as the audio and data communications path for the Unipage system. This bus uses a proprietary architecture to link all of the components of each "Frame" together (the concept of a "Frame" is discussed in sections 4.1.3 and 4.1.4). The "X-bus" also links the Paging Terminal with the Message Manager™ for all audio and data exchange.

Although the Console Computer connects directly to a port on the "central" Main Processor, it too ultimately has access to the "X-bus" since the Console controls all data manipulation with the Paging Terminal and Message Manager™.

Each component in the Unipage system can expand independently of one another, depending on your individual system requirements. In particular, the Paging Terminal itself, which consists of one or more 15-slot chassis, provides the greatest level of versatility. With the 15-slot chassis, almost nothing is discarded or made obsolete, since expansion is achieved by adding card components and additional chassis when needed.

Another key benefit which results from our "modular" design is the Unipage Terminal's "multi-processor" architecture. We define a "multi-processor system" as one where the tasks required of the system are efficiently divided between multiple processors. Therefore, as the system expands, additional processors are added to keep pace with the additional demand for processing "horsepower". What this means for you, the service provider, is that the dependence on the processing power of a single central processor is minimized.

This multi-processor design provides impressive system capacity. Architecturally, the Unipage Terminal can expand to:

Section 7, "System Capacity", takes an in-depth look at Unipage's "multi-processor" architecture, and the major advantages it provides over simpler "single processor" or "co-processor" systems. These advantages include: 3.1) Illustrating How a Unipage System Can Grow

Figure 3 provides a good overview of the Unipage system's remarkable ability to grow without replacing hardly any of the original equipment. The illustration also highlights (by an "*") the components which have been incorporated into the larger system. It is important to note that almost every component, including the chassis, power supplies, Console Computer with VDT, and Card Components continue to be utilized as the system has expanded.

The examples shown in Figure 3 illustrate the Unipage system growing from an estimated 5,000 paging subscribers with the Model 15, to 10,000 paging and voice messaging subscribers with the Model 30, to over 50,000 subscribers with the Model 105.

This 50,000+ subscriber system can further be expanded to support hundreds of thousands of subscribers following the same path these sample systems have followed. In summary, two qualities are always inherent with the Unipage system:

The Unipage hardware architecture consists of three (3) components which are configured together to create a full featured paging and voice messaging system. The three components are the Paging Terminal, the Message Manager™, and the Console Computer.

4.1) Paging Terminal Hardware
The Paging Terminal component of the system utilizes one or more 15-slot rackmounted chassis to perform the paging tasks for the system. This section will provide a more in-depth look at the hardware that makes up this portion of a total Unipage system.

4.1.1) 15 Card Slot Chassis - General Operation
The chassis' function is to house, power, and connect the specific Unipage card components to other 15-slot chassis and to external inputs and outputs in the broader paging network system. Figure 4 illustrates what the Unipage 15-slot chassis looks like. The illustration shows a front view to highlight the card components such as Main CPU, Channel, and Trunk Interfaces. It also shows a rear view to highlight the connections of the chassis.

The 15-slot chassis actually consists of 16 slots, with a built-in power supply on the right (when looking from the front). The slot farthest to the left is unassigned for any purpose, except in special applications involving digital trunks, so for this reason is not numbered. The numbering scheme for the chassis is from left to right (when looking from the front). Therefore, slot #1 is the second slot from the left, and slot #15 is the slot farthest to the right.

The number of slots that are available determines the maximum number of card components that can be contained in a system. Three chassis, for example, will house a maximum of 45 cards. Such a system is known as a Model 45, denoting the number of slots available.

Each particular slot is configured to accommodate a particular type of card. The basic slot configurations in the system are:

The Main Processor Slot is always assigned to slot #15 (farthest to the right when looking from the front), and this rule is without exception. However, it is important to note that not all chassis require a Main Processor Card.

Trunk Slots always start with slot #1 and progress to the right. The number of Trunk Slots can vary, as will be discussed, depending on the cabling configuration.

Channel Slots start at Slot #13 and progress to the left. Again, the number of channels that can be accommodated depends on the cabling configuration.

A Serial Expansion Slot provides two RS-232 (9-pin) serial connectors per slot, for those cards which require an external direct or modem connection to external devices. General applications include connection to an external alphanumeric input device (such as an OAP System or AlphaMate®), and connection to another Paging Terminal using TNPP networking.

General Purpose Slots provide housing for all cards that do not require external connections. This slot type typically houses cards which provide functions such as subscriber record memory, voice prompts, group call processing, and many others.

The chassis is configured at the time of manufacture to meet the needs of our customers' applications. A chassis can be modified to provide greater flexibility in system configuration and can accommodate different configurations for the following: T1 Digital Trunking
The Unipage Terminal supports both full and partial T1 spans, which provide 24 channels per span. One 15-slot chassis can accommodate a full T1 span. Specifically, twelve (12) slots are used to house digital trunk interface cards, with each card supporting two of the 24 channels in the span. Slot #15 is used to house a Main Processor Card, and typically slot #14 houses a Tandem Link (TL) Card (discussed in section which is only required in a Multi-Frame system. The TL Card serves to connect the T1 Trunk Frame to the Main Frame within a Multi Frame system (the concept of a "Frame" is discussed in sections 4.1.3 and 4.1.4). The normally unassigned 16th slot (the slot farthest to the left when looking from the front of the chassis) is used to house a special card known as the T1 Digital Service Unit (DSUT1).

A chassis that supports a full T1 span has one slot available for another purpose. Typically this slot houses a VP8 Card (discussed in section to provide voice prompting. If the service provider only utilizes a portion of the T1, then additional slots are available in the chassis to serve other purposes such as gathering trunk statistics, and providing alphanumeric serial port inputs. Analog trunk interface cards (the TK and TK2 Cards, discussed in section 4.4.4) can also be housed within a partial T1 chassis. E1 (CEPT) Digital Trunking
The Unipage Terminal supports both full and partial E1 spans, which provide 30 channels per span. Each slot of the 15-slot chassis is utilized, again including the normally unassigned 16th slot (slot farthest to the left when looking from the front). A special card known as the Digital Service Unit (DSUE1) Card occupies this slot. Unipage then uses a dual digital trunk card to handle two of the 30 channels per card. Therefore, a full E1 span consists of a DSUE1 Card and 15 Digital Trunk Cards per chassis.

An additional chassis houses the Main Processor Card and Tandem Link (TL) Card which handle the inter-Frame activity with the Main Frame. This chassis can house cards which provide special functions such as voice prompting for automatic paging, trunk statistics, and alphanumeric serial port inputs. The chassis can also accommodate analog trunk cards if needed, utilizing the same Main Processor which is handling the E1 span. Channel Capacity per Chassis
Each chassis can be configured to handle up to six channel outputs, which utilize a total of 12 slots. When a chassis is configured to exclusively handle channel outputs, it is referred to as a "Channel Frame" (discussed in sections 4.1.3 and 4.1.4). A Unipage Terminal can accommodate multiple Channel Frames in systems that utilize a high number of channels. Specifically, the Unipage architecture can support up to 128 channels. Serial Expansion Port Capacity
The standard 15-slot chassis comes equipped with six (6) RS-232 serial port connections (9-pin). The slots which are wired with these connections are #11, 14, and 15. However, the chassis can be equipped with one of two options which expand the number of connections by 12 and 18, respectively.

The first option is a 12 serial port expansion panel which is added to the backplane of the chassis itself. These 12 connections, in conjunction with the six that already exist, provide 18 connections on the chassis. Since each slot accommodates two serial port connections, this translates into nine (9) total slots which are capable of serial port access.

With the 12 port expansion panel, slots #4-9, 11, 14 and 15, are wired for serial port connection. As mentioned previously, slot #15 is reserved for the Main Processor (in those chassis that require one), and slots #12-13 are reserved for the Channel Set.

The second option is an 18 serial port expansion panel. This functions in the same manner as the 12 port panel, but adds an additional 18 ports, or nine (9) slots, of serial port access in the chassis. With the 18 port panel, a total of 12 out of the 15 slots are configured with serial port access. Specifically, slots #2-11, 14 and 15, are wired for serial port connection. Power Options
Unipage supports all standard power supplies, including 220 VAC 50/60 Hz, -48 VDC, and 110 VAC. The power supply simply needs to be designated at the time of the initial order. The Unipage can also provide 240 VAC 50 Hz power when the equipment is mounted in a Large Floor Standing (CB3) Cabinet (discussed in section 4.5.3). Contact your Motorola Representative for details if you require 240 VAC 50 Hz power.

4.1.2) Unipage Model 15
The Unipage Model 15 is capable of providing full Paging Terminal functionality and therefore serves as our basic Terminal offering. What makes the Model 15 different from the 15-slot chassis we have been discussing is the addition of a Main Processor Card. This card, as indicated by the name, serves as the Main CPU for the entire Paging Terminal.

As the Unipage system grows, additional Main Processor Cards may or may not be needed, depending on the size and configuration of the system. Whether or not additional Main Processors are utilized is a function of whether or not the system is configured as a "Single-Frame" or "Multi-Frame" system. A detailed explanation of each configuration is given below.

4.1.3) Single-Frame Configuration
To accomplish the task of configuring individual chassis within a total system, the Unipage system arranges specific chassis into what we refer to as "Frames". A Frame is best defined as "a configuration of one or more chassis which utilize(s) one Main Processor Card to coordinate the tasks of the card components housed within the chassis".

Since every chassis does not necessarily require its own Main Processor Card, there can be one or more chassis that are connected to another chassis which does contain a Main Processor Card. Typically this is the case with smaller systems, where one Main Processor can easily handle all of the system functions. Such systems are referred to as "Single-Frame" systems.

The maximum number of chassis that can be contained in a Single-Frame system is four (4). Therefore, under any circumstance, a Single-Frame system has a maximum of 60 slots (otherwise known as a Model 60).

4.1.4) Multi-Frame Configuration
A Unipage system becomes "Multi-Frame" when more than one Main Processor Card is utilized in the system. In such a configuration, one Main Processor serves as the "central" processor, coordinating all of the tasks of the total system. All other Main Processors are therefore subservient to this "central" Main Processor.

The Frame which contains the "central" Main Processor is referred to as the "Main Frame". This Frame typically contains all of the vital functions of the Terminal minus the trunk and alphanumeric inputs. Vital functions include but are not limited to subscriber record memory, system networking, and channel encoding output.

The "subservient" Frames typically handle the trunk inputs for the system, since this configuration represents the most efficient use of Unipage's multiple processors. Such a Frame is known as a "Trunk Frame". However, Frames can also be configured to specialize in other functions such as channel outputs ("Channel Frame"), TNPP networking connections ("TNPP Frame"), and alphanumeric inputs ("Alpha Frame").

Figures 5 and 6 provide two examples of Single-Frame systems. 5 is a Model 15 which can handle approximately 5000 subscribers, and 6 is a Model 30 with Message Manager™ which can handle approximately 10,000 subscribers. Figure 7 shows a Multi-Frame configuration for approximately 50,000 subscribers. The illustration shows one Main Frame, four Trunk Frames, and one Alpha Frame. The channel outputs in this example are contained in the Main Frame.

Take a minute to identify the terms on the illustrations that have been discussed so far, such as "Main Frame" and "Trunk Frame". Understanding how the Unipage Modular Paging Terminal is configured points out our inherent architectural advantage when it comes to system expansion and call processing capacity.

4.2) Message Manager Hardware
The Message Manager™ is an optional component which provides custom greetings, numeric page insurance, voice page insurance, and voice messaging features. The Message Manager™ is required if Alpha Transcription is used in the system.

4.2.1) General Operation
The Message Manager™ is a PC-based voice messaging system which is fully integrated with the Paging Terminal. Generally speaking, the Message Manager™ receives incoming messages from the Paging Terminal and stores them on its hard drive for future retrieval. Subscribers can retrieve their messages by accessing their personal "mailbox" and inputting commands using a DTMF telephone.

The MM unit is configured with the 15-slot chassis of the Paging Terminal to create a system that is capable of both paging and voice messaging functionality. The Paging Terminal portion (the 15-slot chassis) provides the trunk interface connections. The Message Manager™ provides storage on its hard disk for customized and standard voice messaging system prompts, and all incoming voice messages to system subscribers. It is important to note that the Message Manager™ uses a RAM disk to store the most commonly used messaging prompts. This process lessens the need for hard disk access and storage.

Specifically, each Message Manager™ unit ("MM unit") consists of an 80486 processor for call control and data processing, and four (4) 80188 processors for voice "analog to digital" (A/D) and "digital to analog" (D/A) handling. The A/D and D/A function is more commonly referred to as "voice buffering", where each conversion (A/D or D/A) is handled by one voice buffer.

4.2.2) Single-Frame Configuration for Message Manager™
In a Single-Frame configuration, all Message Manager™ components including the disk drive, or drives if redundant, are housed in one standard rackmounted chassis (referred to above as an MM unit). This MM unit is specifically designed to handle the voice messaging components and does not resemble the standard 15-slot chassis. In looking at a Single-Frame system, the MM unit would physically be located beneath the one or more 15-slot chassis.

Within a Single-Frame configuration, the Message Manager™ can provide up to 16 voice buffers. Specifically, the Message Manager utilizes a quad voice buffer card, each having its own 80188 processor for voice data handling. Four of these cards can be housed in one MM unit, therefore, producing the 16 voice buffers.

What 16 voice buffers means for the total system is that a total of 16 messages can be simultaneously recorded to or retrieved from the Message Manager™ hard drive. Therefore, if the traffic on a particular system exceeds 16 simultaneous voice messaging calls during the busiest hour of operation, then the system can be expanded to a Multi-Frame configuration.

The MM unit can be configured with a second hard drive to provide redundancy, or "mirroring", for the Message Manager™'s primary hard disk in the event of a disk failure.

4.2.3) Multi-Frame Configuration for Message Manager™
The Message Manager™ follows a similar expansion path as the Paging Terminal itself. Just as the 15-slot chassis of the Paging Terminal can be configured into a Multi-Frame system, so too can the Message Manager™. As with the 15-slot chassis, the Message Manager™ components can be reconfigured without the need to discard the hardware components. Although typically an upgrade from a Single Frame to a Multi-Frame system involves replacing the hard drives with larger sizes, it is possible to reuse the drives if desired. Reusing the drives does require formatting the drives for compatibility with the Novell® Operating System software.

Configuring the Message Manager™ into a Multi-Frame system involves removing the disk drive or drives from the original MM unit, and configuring the Message Manager™ into a Local Area Network (LAN) which uses Novell® EtherNet® software to operate. The LAN utilizes a common system File Server which houses the hard disks for all the MM units, now referred to as "MM LAN units".

The File Server itself is housed in a rackmounted chassis which from the exterior is identical to the MM LAN unit. The File Server comes standard with redundant ("mirrored") disk drives to protect the voice message data in the event of a disk failure.

The MM LAN units provide the EtherNet® interface for the LAN, and the A/D and D/A conversion (voice buffering) required between the Paging Terminal and the MM LAN. The A/D conversion is utilized for the recording of audio to the hard disks in the File Server, and D/A conversion is utilized for the playback of audio from the hard disks.

In a Multi-Frame configuration, each MM LAN unit is configured with a Trunk Frame. There is also an MM LAN unit connected to the Main Frame of the system. Each MM LAN unit still contains up to 16 voice buffers, with the exception of the MM LAN unit for the Main Frame which only requires four (4) voice buffers for most applications. Four buffers always come standard with the MM and MM LAN units.

It is important to note that one (1) voice buffer is needed for each voice paging channel on the system that stores a voice page to the Message Manager's hard disk. Since all Multi-Frame systems necessarily use this method, one additional buffer is needed for every voice channel beyond four, since four voice buffers come standard.

In a Multi-Frame system, the total number of voice buffers multiplies by the total number of Trunk Frames in the system. For example, if the system contains six (6) E1 Trunk Frames with Message Manager™, the total number of voice buffers is now 96.

If a particular T1, E1, or analog Trunk Frame is not required to provide voice messaging service or numeric page retrieval, the MM LAN unit can be eliminated from the Frame. The same applies to Trunk Frames that have less voice messaging traffic. In this case, the MM LAN unit can contain fewer voice buffers to handle the call traffic.

4.2.4) Disk Drive Options
Each Message Manager™ unit can be equipped with numerous sizes of disk drives, depending on the amount of voice storage time required on the system. The standard disk sizes range from 100 MB to 1 GB. The File Server typically comes equipped with a 1 GB disk drive which provides approximately 72 hours of voice storage. Motorola can configure a multi-Gigabyte Message Manager™ for systems that require such capacity.

4.3) Console Computer Hardware
The Console Computer is a required component in the Unipage system. The Console is used to manipulate and review all the system data contained in the Paging Terminal and the Message Manager™. The Console Computer operates separately from the Paging Terminal and Message Manager™.

The Console Computer, by design, maintains a "mirror image" of the Paging Terminal and Message Manager™ parameters, and the subscriber database. Therefore, running complicated and/or lengthy reports, and performing diagnostics, does not hamper or reduce the throughput of the Paging Terminal in any way. Reports can even be generated with the Console disconnected from the Paging Terminal altogether, which illustrates the Unipage system's true "modular" architecture.

Such functionality is in contrast to "single" and "co-processor" systems that must utilize one central processor to perform both page encoding and report generation/diagnostics. Running a complicated report during a peak traffic period on such a system will likely hamper the primary function of the Terminal which is to perform page encoding. Unipage's "modular" architecture ensures that major system tasks are handled by separate processors, avoiding an overload to the system.

4.3.1) General Operation
The Console is a rackmounted 80386 or 80486 Computer which resides in the same cabinet as the rest of the Unipage equipment (15-slot chassis and Message Manager™ chassis). The Console Computer can also be a table-top version if specified at the time of the original order.

The Console operates the Unipage Console Software which controls basic functions of the system as described in section 5.2, "Console Features". The Console Computer is connected to the Paging Terminal via RS-232 serial port connection located on the back of the M15 chassis. The Console, depending on the model, also provides serial port connections to remote VDT's and billing systems, and a parallel port connection to a printer.

Each Console Computer comes loaded with Operating Software and Unipage's Proprietary Console Software. These Software packages vary depending on the model of Console Computer purchased.

The basic Console Computer is a 386DX with 116 MB hard drive and 4 MB memory. More powerful versions, including a 486DX with 200 MB hard drive and 24 MB memory, are available for Consoles that are performing multiple tasks.

4.3.2) Console 4 Software
Console 4 is Unipage's latest System Software platform. Unipage is continuously upgrading this platform by releasing new versions which contain feature and function enhancements. section 5.2, "Console 4 Features", provides an indepth look at the latest features available.

For single-user Console Computers, Console 4 runs on DOS. For multi-user Consoles, PC-MOS® is used because of the requirement for multi-tasking/user operating software. Console 4 Software also has a DBase III® compatible file structure.

4.3.3) Single-User Console 4 Computers
This basic Console Computer is a 386DX with an 116 MB disk drive and 4 MB of memory. The purpose of this model is to provide a cost effective solution for service providers who only require one-user access to the Paging Terminal with no additional external connections.

This basic Computer can be equipped with a Remote Access Modem which provides an additional serial port connection. The primary purpose of this port is to allow Motorola's Technical Service Department access to the Console for maintenance purposes. However, the port can be used by the system operator for general remote Console programming and maintenance as well.

The single-user Console can further be enhanced with the addition of a Buffered Input/Output (BIO) Port. The purpose of this port is to interface with an external billing system which programs subscriber records and reads pager call counts contained in the Unipage system. The BIO utilizes an RS-232 serial port connection.

4.3.4) Multi-User Console 4 Computers
Unipage offers three levels of multi-user Console 4 Computers: nine-user, 15-user, and 25-user. "Multi-user" refers to the ability to connect remote VDT's or PC's with emulation software to the Console Computer for the purpose of programming pagers in the Paging Terminal.

All of the multi-user Consoles have PC-MOS® Operating Software which allows for multi-tasking. Both the nine-user and 15-user Consoles are 386DX's with 200 MB hard drives. Their memory capacity is 8 MB and 16 MB, respectively. The CX25 is a 486DX with 200 MB disk drive and 24 MB of memory. All the Console Computers can be equipped with a 486 processor option if required. A 486 processor is recommended if the BIO is utilized.

All three multi-user models come equipped with the Remote Access Modem and the BIO Port. All the connections are 25-pin serial ports, with the exception of the two (2) BIO ports, which are 9-pin ports.

4.4) Card Component Hardware
The Unipage system's card components represent the foundation of the Paging Terminal, since the 15-slot chassis serves no other purpose but to house, power, and connect the various cards that populate it.

The Unipage Card is a Printed Circuit (PC) Board designed to handle a specified function such as Main, Channel, Trunk, and Network processing, as well as all other Paging Terminal functions. Each board occupies a slot within the 15-slot chassis, and its placement depends on the wiring of the chassis, as discussed in section 4.1 "Paging Terminal Hardware".

4.4.1) System Processor Cards
The System Processor Cards perform vital processing functions for the Paging Terminal including central processing and serial port processing for alphanumeric paging. Specifically, Unipage offers a Main Processor Card and an Expansion Processor Card. They are the MA3 and EXP3, respectively. Main Processor Card (MA3)
The Main Processor provides the CPU function for the total Paging Terminal. Generally speaking, the Main Processor coordinates all the data exchange between processors within the Paging Terminal, as well as between the Console Computer and the Message Manager™ as they interact with the Paging Terminal. The Main Processor interfaces with the Console Computer via an RS-232 serial port on the Processor itself. The Main Processor interfaces with the Message Manager™ via the Unipage system's proprietary "X-bus".

The standard MA3 works within Unipage's distributed architecture to process 11 pages per second (assuming a 10 digit numeric page or one TNPP ID Page). This translates to 39,600 numeric pages per hour. If the system "busy hour call rate" (BHCR) is 20%, then the maximum number of subscribers is 198,000 when using the standard MA3.

Unipage also utilizes a high speed Main Processor (MAX) Card which increases the above numbers four-fold. Motorola recommends the use of the high speed Main for very large systems that require additional processing capability. The MAX Card is only available with special approval from Motorola.

Specifically, the high speed Main will handle 45 pages per second. This translates to 162,000 pages per hour. With a 20% call rate, the maximum number of subscribers this card can handle is 810,000.

The MA3 and MAX also contain a parallel input/output (I/O) port which provides for printer logging of the Frame's activity. Expansion 3 Processor Card (EXP3)
The EXP3 Card provides serial port connections for alphanumeric paging input into the Paging Terminal. The EXP3 provides two (2) RS-232 serial port connections which allow for 300/1200 auto-baud communications. The EXP3 requires an external modem per port. Motorola can provide this modem, which is a 300/1200 auto-baud, line powered dial-up modem.

The paging protocol that the EXP3 accepts is the industry standard Telocator Alphanumeric Protocol (TAP). The maximum number of characters per message is 1000.

The Unipage system allows for a maximum of four (4) EXP3 Cards in the Main Frame per system. Each Trunk or Alpha Frame can contain up to eight (8) EXP3 Cards, for 16 ports per Frame.

4.4.2) Subscriber Memory Cards
These cards provide varying levels of subscriber record memory for the Unipage system. The MX Series Cards can be added together to provide cumulative memory.

The MX Series Cards are the MX16, MX32, and MX64, which provide 16,000, 32,000, and 64,000 subscriber record memory, respectively.

The MX Cards can also be configured to be redundant within the same Frame. For example, two MX64 Cards can be contained in a Frame to provide 64,000 subscriber record memory. The two cards operate simultaneously and are both updated if changes are sent from the Console Computer. If one card fails, the second card automatically continues to operate.

There is no limit to the number of subscriber records that can be made redundant aside from the current 256,000 limit of the Console itself. A total of eight (8) MX64's can be used to provide 256K subscriber record memory which is redundant.

Conversely, if the cards are not configured for redundancy, then two MX64's will provide 128,000 records. However, a failure of one card in a non-redundant configuration will result in the loss of 50% of the subscriber records until the faulty card is replaced. Upon replacement, the records can be quickly downloaded from the Console Computer to bring the memory back on-line.

4.4.3) Channel Controller Card Set
The Channel Controller Card Set is a two card set, with each card working together to provide both analog and digital paging over an RF paging channel.

Specifically, the Channel Cards receive paging information from the Main Processor Card and buffer the information before it is encoded. The Channel Cards encode the paging information based on encoding format (POCSAG, GSC, etc.) as well as priority status. Once encoded, the batched pages are sent to the RF Transmitter Controller.

The Channel Controller can interface directly with numerous transmitters or with a Transmitter Controller to provide RF system control. For systems with no Transmitter Controller, the Channel Controller can emulate Motorola PURC - Tone (Keyup - Analog & Digital, TX Knock Down - Zoning, Frequency Select); Quintron SCU/SCM (Keyup - Analog & Digital, Analog or Digital Priority - who gets 660 Hz); Quintron DCU (Omega 3.0 and 4.0, Keyup - Analog & Digital, Mode Change, Unkey, Frequency Select - F1 through F4); MicroLink 20X (Keyup - Analog & Digital, Unkey, Mode change, each command is sent once); and MicroLink 20R (Keyup - Analog & Digital, Unkey, Mode change, and zoning).

4.4.4) Trunk Interface Cards
The Trunk Interface Cards provide the primary interface with the PSTN. In particular, these cards support both analog and digital trunks. Trunk configurations include selector level, end-to-end, 2-wire E&M, or outdial. Supported signaling includes DTMF, MF (both MF-R1 and MFC-R2), and Dial Pulse. Trunk Interface Card (TK)
This trunk card supports a single analog trunk coming from the PSTN. This card can be configured for selector level, end-to-end, 2-wire E&M, or outdial. Dial Pulse and DTMF are supported as standard. MF-R1 is supported with the MF-R1 option. An LED digit-display comes standard. Dual Trunk Interface Card (TK2)
This analog trunk card supports two trunks from the PSTN and can be configured for 2-wire selector level and end-to-end only. With the addition of a Multi-Frequency (MF) Daughter Board, this card can support MF-R1 and MFC-R2 signaling. It can be optionally equipped with a dual-digit LED display. This display is designed for periodic use and not for permanent placement on the TK2 Card. T1 Dual Trunk Interface Card with MF-R1 (TKT1)
This trunk card supports two of 24 channels contained in a full T1 digital trunk span, and supports MF-R1 signaling. The use of this card requires a 15-slot chassis specifically designed to support T1 (known as a D15 chassis). This card also requires one (1) special interface card, known as a T1 Digital Service Unit Common Card (DSUT1), per T1 span to operate. The DSUT1 Card serves as the interface between the T1 span from the PSTN and one T1 Trunk Frame. Any number of TKT1 Cards between 1 and 12 can be used in a T1 Trunk Frame depending on the number of T1 channels utilized.

The Unipage digital Trunk Frame arrangement provides two key benefits:

Sparing costs are very low because only one (1) inexpensive spare trunk card is needed to support the entire T1 span. Secondly, replacement of a defective trunk card is as easy as sliding out the old card and putting in the new one. As will be discussed in section 9, "Spares and Maintenance", card components can be replaced without having to power down the system. What this means for you, the service provider, is that no interruption of service is required for most card replacements. E1 (CEPT) Dual Trunk Interface Card with MFC-R2 (TKE1)
This trunk card supports two of 30 channels contained in a full E1 digital trunk span, and supports MFC-R2 signaling. The use of this card requires a 15-slot chassis specifically designed to support E1. This card also requires one (1) special interface card, known as an E1 Digital Service Unit Common Card (DSUE1), per E1 span to operate. The DSUE1 Card serves as the interface between the E1 span from the PSTN and the E1 Trunk Frame it is housed in. Any number of TKE1 Cards between 1 and 15 can be used in an E1 Trunk Frame depending on the number of E1 channels utilized.

4.4.5 Optional Cards
This category covers all of the remaining cards available for the Unipage system, with the exception of Alpha Transcription which is covered in section 4.4.6. The functionality of these cards ranges from voice prompting to TNPP networking. Voice Prompt Card (VP8)
The VP8 provides shared system voice prompts for paging subscribers. Specifically, there are five standard prompts which assist callers in all aspects of entering a page:

The VP8 can be customized to any language, accent, or verbage. In a Multi-Frame system, one VP8 is needed for every Trunk Frame that requires system prompting. Quad Store Card (QS)
This card is used solely for voice paging in a Single-Frame system where a Message Manager™ is not utilized. The QS Card provides four (4) 28-second voice buffers (so therefore can handle four simultaneous calls) to record messages coming in on the Trunk Interface Cards. A voice buffer is not available for another call until the call that is currently being stored is "played out" over the channel by the Channel Controller. The QS does not provide storage of the message after the message is sent out as a page.

If message storage for future retrieval is required, the Message Manager™ must be used. In this configuration, voice pages are recorded to the Message Manager™ hard disk instead of being handled by the QS Card. The Message Manager™ then sends the message to the Channel Controller. The hard disk retains the message to allow the subscriber to retrieve it by accessing the Message Manager™. Telocator Alpha Protocol Input Card (TAP)
The TAP Card is a high speed version of the EXP3 Card. The TAP Card is capable of supporting a 9600 Baud connection, but also can be manually set for lower speeds. This card is used in applications that require a higher speed connection. It is also used when more than four EXP3 Cards are used in a system. TDD Interface Card (TDD)
TDD is a protocol used to help the hearing impaired communicate more effectively. Unipage provides a card which can interface with input devices which utilize the TDD protocol. A special TDD modem is required when using this card. This modem is available from Motorola. Group Processor Card (GP)
This card enhances the Unipage Terminal's ability to provide the Group Call feature. Without the GP Card, the Unipage Terminal can simply provide sequential group call paging. The GP allows random assignment of up to 9,999 pager numbers to a Group Call, and also expands the total number of Groups allowed on the system to 9,999. Statistics Processor Card (ST)
The ST Card provides detailed statistics on trunk usage. One ST Card is needed for each Trunk Frame that requires statistics to be gathered. The purpose of the ST Card is to allow the service provider to analyze trunk usage so that under or over utilization does not occur, and to evaluate how often certain trunk conditions exist on the system.

Specifically, the ST Card provides nine (9) accumulators which can be set to increment every time a particular trunk state occurs. The ST Card allows the service provider to define trunks into a common "trunk group" within a trunk Frame so this group can be analyzed. For example if a trunk frame contains a T1 span for a total of 24 channels, a "trunk group" can be created that gathers statistics on channels 1 12.

The following is a listing of the trunk states that can be tracked:

00 Trunk Idle
01 Waiting for digits
02 Waiting for 2nd digit
03 Waiting for 3rd digit
04 Waiting for 4th digit
05 Waiting for 5th digit
06 Verifying subscriber

44 Connected to Message Manager in command mode
45 User-controlled options
46 Voice paging being recorded to disk
47-63are currently undefined

The Stats Processor is programmed from the Console Computer. The service provider can set the ST Card to gather statistics immediately upon receiving a proper command, or at an hourly increment so the time interval can be measured. The statistics can be logged to a parallel printer, VDT, or a PC running Emulation software.

A more detailed explanation of the Statistics Processor is contained in the "Statistics Processor" Manual. Fast Load Card (FL)
This card increases the effective Console baud rate to nearly 38.4Kbps for the purpose of downloading subscriber record information from the Console to the Paging Terminal. This card primarily is used if the Paging Terminal requires a download after an MX Card failure, and is recommended for systems with more than 10,000 subscribers. Redundant Switch Link Card (RS)
This card is only used in redundant Unipage systems or systems that require an Alarm Panel. The RS Cards are used to keep the data contained in the "secondary" side of a redundant system up to date. An RS Card on the "primary" side is in constant communication with an RS Card on the "secondary" side. In the event of a "primary" side failure, the "primary" RS Card will command the RS Controller (which will be described in the "Redundant Operation" section) to switch all I/O to the "secondary" side. When the "primary" side becomes operational, the RS Controller will switch all I/O back to the "primary" side. Alarm Panel (AL)
The Alarm Panel consists of two (2) modules - the RS Card and another card in the Fan Panel. The Alarm Panel also comes equipped with an LED display panel and speaker to indicate an alarm condition.

The Alarm Panel monitors two operational conditions of a system Frame including 48 VDC power supply and card chassis operation. There is also an external non system contact closure alarm input which can be wired to external equipment. Quad Modem Card (QM)
This card allows the Unipage system to accept dial-up alphanumeric pages via D.I.D. trunks. The QM Card provides four (4) modems for alphanumeric input. Tandem Link Processor Card (TL)
The TL Card provides the serial communication link between different Frames in a Multi-Frame system. If there are two or more Frames in a system, each "secondary" Frame must contain a TL Card to communicate with the Main Frame, which contains the Main Processor. In turn, the Main Frame requires one TL Card for every two "secondary" Frames (such as a Trunk Frame) since each TL Card has two ports. TNPP Network Interface Card (NW)
This card is used to provide networking between Terminals using the industry standard TNPP protocol. Each NW Card provides two ports for non-voice calls to be passed from system to system using the TNPP format. An external modem is required for each connection. The Unipage Terminal can support up to four TNPP connections per system if full TNPP routing capability is required.

If additional full-routing TNPP connections are required, Motorola's system engineering group can work with you to configure a networking solution. NetUni Network Interface Card (NU)
This card is used for specialized zoning applications where a single page needs to be regenerated multiple times and sent to multiple channel controllers. FAXPage (FAXP)
This PC-based product stores alphanumeric pages and sends them in ASCII format to a specified FAX machine. These alpha pages are sent to the FAX in scheduled groups. This product is only available through special approval from Motorola.

4.4.6) Alpha Transcription (AT)
Alpha Transcription consists of a two card set, with a VDT, keyboard, and headset for use by an operator. AT combines OAP functionality with Message Manager™ voice messaging to create a partially automated approach to alphanumeric paging.

With a standard OAP system, the operator communicates directly with the caller to receive the message. The operator then enters the message into the OAP system, which passes it to the Paging Terminal via TNPP.

With Alpha Transcription, the caller deposits a voice message in a Message Manager™ voice mailbox. The operator is audibly and visually alerted by the VDT that a message is waiting in queue. The operator can hit a key on the VDT keyboard to retrieve the message in the mailbox, and enter the message into the Paging Terminal through the VDT.

Advantages to Alpha Transcription are the following:

4.5) System Cabinets
Unipage provides three sizes of cabinets depending on the initial size of the system and its expected growth rate.

4.5.1) Desktop Cabinet (CB1)
This cabinet is for a Model 15 Paging Terminal only. To use this cabinet, the Console Computer must be a tabletop type, and the system cannot have Message Manager™. Housing any of these components in the cabinet will require going to the next larger size. The Desktop Cabinet is approximately 10 in x 21 in x 21 in (25.4 cm x 53.3 cm x 53.3 cm) (HxWxD).

4.5.2) Small Floor Standing Cabinet (CB2)
This cabinet is for Model 15 to Model 45 systems that do not anticipate much system growth. The cabinet is approximately 30 in x 22 in x 32 in (76.2 cm x 55.9 cm x 81.3 cm) (HxWxD).

4.5.3) Large Floor Standing Cabinet (CB3)
This cabinet is the most commonly used because it comes equipped with a Fan Panel at no additional cost and provides ample room for system expansion. The cabinet is approximately 73 in x 24 in x 32 in (185 cm x 61.0 cm x 81.3 cm) (HxWxD). If this cabinet becomes full, additional large cabinets can be added to allow for system expansion.

The Unipage system provides a full range of features including voice messaging, alphanumeric, and networking capabilities. Features can be added at any time as a result of Unipage's advanced "modular" architecture.

5.1) Terminal Features
The features inherent to the Paging Terminal result from the Card Components that populate the 15-slot chassis. Although detailed explanations of these cards are given in section 4.4, "Card Component Hardware", the following section highlights many features that add advanced functionality to the Unipage system. Many of the features reside in the Main Processor Card, which coordinates all of the activity in each Frame of the Unipage system.

Many of the features described in "Terminal Features" are also contained in other portions of the "Unipage Features" section. Some overlap exists in describing the features of the Paging Terminal, Message Manager™, and Console Computer because all of these components work together as one integrated paging and voice messaging system.

Also, several of the features listed in this section require special system configurations, primarily in the area of networking. These features are highlighted with an "*". Other features listed below have already been implemented in the Asian market, and can be implemented in the Americas and Europe when requested. Features that fall into this category are marked with a "#".

For all of these special features listed below, Motorola's system engineers can work with you to incorporate them into your paging system.

5.1.1) T1 Digital Span and MF-R1 Signaling
The Unipage Terminal is capable of accepting T1 digital spans, which are equivalent to 24 standard analog trunks per span. The Unipage can also accept MF-R1 signaling to receive the calls through the T1 span.

5.1.2) E1 (CEPT) Digital Span and MFC-R2 Signaling #
The Unipage Terminal is capable of accepting E1 (CEPT) digital spans, which are equivalent to 30 standard analog trunks per span. The Unipage is currently capable of handling the Chinese version of MFC-R2 signaling.

Since the Unipage system provides a high level of MFC-R2 call processing flexibility, Motorola's installation engineers can modify the R2 call script to support the numerous variations of R2 signaling found throughout the world. Some development work may be required to modify the MFC-R2 to fit a particular nation's specification.

5.1.3) Temporary Barring #
The Unipage Terminal allows for Temporary Barring of service to a caller on the system. If barring is implemented, the subscriber will hear a shared greeting prompt which is created by the service provider indicating service has been temporarily discontinued for the subscriber. The subscriber activates/deactivates this feature by contacting the service operator. This feature will be subscriber settable in the second half of 1994.

5.1.4) Network Call Counting #
This feature provides a total call count for all network calls a subscriber receives. With this feature the service provider can charge a flat rate for local paging service, and charge on a "per call" basis for all network pages. It is important to note that when this feature is enabled, no local calls are counted. This feature can be implemented on a per subscriber basis. The network call count is logged in the Console's "Call Count" data field in the subscriber record (refer to section, "Call Count Field" for a description of this field).

5.1.5) Call Logging
The Main Processor Card in the Main Frame provides a detailed call log for all pages that come into the system. This log differs from the Console program's "Call Count" field (described in section 5.2.5, "Console Subscriber Record Data Fields") which logs the number of pages to the subscriber's pager. The Main Processor Call Log provides the following information for each call logged: date, time, input ID the call came in on, subscriber ID, channel that page was sent to, signaling format, function, message class, and page contents. An example of a call log is the following:

01/06/94 17:10:54 01 2243509 0A32 This is a test message

"01/06/94" is the date; "17:10:54" is the time; "01" is the input ID (see the reference to "Trunk ID" in section, "Status Display", for more details); "2243509" is the subscriber ID; "0A32" are the codes used to identify the channel the page was sent to, encoder signaling format, pager function and message class, respectively; and "This is a test message" is the message sent to the pager.

At various times, the system operator can cause all "X-bus" commands to be sent to the call log. This unique feature can assist the service provider in locating problems caused by a failed component in the Paging Terminal or Message Manager™.

Call logging information can be logged to a parallel printer port or to a serial port. The serial port can accommodate a VDT for "live" monitoring, or a PC with a communications program to write the data to a file on its hard disk.

5.1.6) TNPP Networking Capability
TNPP networking capability is essential in today's paging system environment. Systems today can include multiple Terminals which are all interconnected. TNPP represents the paging industry standard to accomplish interconnectivity between Terminals from different manufacturers.

The Unipage system is capable of providing four (4) full-routing TNPP connections using TNPP Network (NW) Cards. If additional partial or full-routing TNPP connections are required in a system, Motorola can configure a networked system to fit your needs.

5.1.7) Selectable Acknowledge Tone Prompts
The Unipage Terminal allows for different tone prompts when the caller reaches the system. The tone prompts represent different "beep tone" cadences which can be chosen based on the service provider's preference.

5.1.8) Delayed Repeat Page
The standard Paging Terminal provides a "repeat page" feature in which the second page immediately follows the first page being sent out over the channel. For service providers who require the repeat page to be delayed, a card known as the EXTRA Card must be used. This card allows the repeat interval to be set on a system-wide basis. Whether a subscriber receives a repeat page is programmable on a per subscriber basis.

5.1.9) Programmable Maximum Numeric Page Length
The maximum page length for both Golay and POCSAG numeric pagers is programmable on the Unipage system.

5.1.10) Automatic Network Registration #
This feature will be available by the second half of 1994 and will allow the subscriber to control via DTMF telephone the "follow me" network coverage he receives. After the subscriber calls his own pager telephone number, enters the Message Manager™ command mode and enters his security code, the subscriber will then be able to enter a command which allows him to change network coverage.

It is important to note that this feature will only be available from the subscriber's "home" Terminal. If the subscriber wishes to change network coverage while he is away from his "home" Terminal, he can contact the local service operator, and the operator can change his network coverage. The operator will be able to do this through another feature, "Remote Database Access via TNPP Networking", explained below in section 5.1.11.

5.1.11) Remote Database Access via TNPP Networking *
Available by the second half of 1994, this feature will allow a system Console operator to access any Console database within the Unipage network. The operator will be able to pull up and modify subscriber records and perform other Console functions such as maintenance. Access to remote databases is controlled by security code access, and the access levels can be set for variable levels as explained in sections and of "Console Features".

5.1.12) Expiry Date Feature
This feature is also discussed in the "Console Features" section under, and provides the ability to set a date in which a subscriber's service will be inactivated. As the expiration date approaches, the Unipage system will automatically send out a "warning" page indicating that service is about to expire. If the subscriber does not renew his service, the system will send out a "service termination" page and then "invalidate" the subscriber's record, which turns off service.

The following items can be set by the system operator: 1) message content of the "warning" and "service termination" pages, 2) the time of day to automatically run the Expiry Date program, and 3) the number of days prior to "service termination" that the "warning" page is sent (maximum 6 days).

5.1.13) Paging Terminal Redundancy
The Unipage Paging Terminal is capable of various levels of redundancy, depending on the service provider's needs. A detailed explanation of this redundancy is discussed in section 6, "Redundant Operation".

5.1.14) System Voice Prompts
The Unipage Terminal provides shared system voice prompts for paging service. These prompts are provided by the Voice Prompt 8 (VP8) Card which is explained in section

5.1.15) Hidden Mailbox Feature #
This feature allows a caller to revert to a subscriber's Message Manager™ voice mailbox if no DTMF digits are entered. The caller is sent to the mailbox after a "time out" period, which is a programmable period of time. This feature is designed to allow callers without DTMF telephones to access the Message Manager™, and the feature is programmable on a per subscriber basis.

5.1.16) Numeric Page Discard
This feature allows a caller to discard the numeric page that he has entered via DTMF telephone by hitting either "**" or "****". Entering the stars will reset the trunk and allow the caller to begin again.

5.1.17) "Canned Messaging" for Alphanumeric Pagers
The Unipage system supports the "canned messaging" feature that is programmed into many alphanumeric pagers on the market. The Unipage sends the appropriate predetermined code to the pager, and the pager converts it into the corresponding message stored in its memory, such as "call the office".

5.1.18) Alphanumeric Input Via Direct Inward Dial (DID) Trunk
The Quad Modem (QM) Card, discussed in section, allows the Unipage system to interface with an alphanumeric input device, such as the AlphaMate®, through a DID trunk interface card. This card eliminates the need for a serial port dial-up modem and dial-up telephone line connection to serve this purpose. The use of the Quad Modem Card is not recommended for all systems and should be evaluated by your Motorola Representative.

5.1.19) TDD Interface Capability
TDD stands for "Telephone Device for the Deaf". A TDD is a telephone replacement that provides the user with a display screen, keyboard, and modem connection to other TDD users. The Unipage system has the capability to allow a caller who is using a TDD to telephone the system and send a page to a subscriber. Refer to section, "TDD Interface Card (TDD)" for additional information.

5.1.20) Overdial Access from a DID Trunk
Typically, overdial access is used in conjunction with an end-to-end (ETE) trunk. An ETE trunk requires the caller to enter "overdial" digits via DTMF telephone to identify the subscriber pager number. The caller must enter this information because, unlike a DID trunk, no digits are passed from the PSTN to the Unipage system identifying the subscriber pager number. The Unipage allows overdial access by dedicating a special subscriber ID through a DID trunk as an "overdial input" service ID. This feature allows the operator to add more subscribers without purchasing new telephone numbers from the telephone service provider.

5.1.21) Universal Group Paging
The Unipage system allows different pager types, such as POCSAG, 5-tone, and Golay, to be mixed within the same pager group. The pagers' numbers must be sequential unless the Group Processor (GP) Card is used (discussed is section If different function pagers are mixed in the same group, the message received by each pager will vary. For example, if a caller sends a numeric page to a group containing a tone, numeric, alpha, and voice pager, the page received by each would be a tone alert, numeric display, numeric display, and tone alert, respectively.

5.1.22) Call Countdown Feature
This feature allows the service provider to program a subscriber's pager to receive a set number of pages before it is "deactivated". Each page to the pager will increment the call count downward until it reaches "zero". At "zero", the subscriber's service is "inactivated" until additional service is provided by the service provider. This feature is useful for demonstration pagers or for metered service for a given period of time.

5.1.23) CLI Handling Script #
The Unipage Terminal is capable of processing the Calling Line Indicator (CLI) that may be passed from the PSTN. Typically, CLI works in conjunction with an E1 (CEPT) span which is using MFC-R2 signaling to communicate with the Unipage. Currently, no established specification exists in North America for a paging application with CLI. However, the Unipage system's flexibility in handling the incoming CLI will allow Motorola to accommodate it when more detailed specifications emerge from the telephone service providers.

5.2) Console Features
The Console Computer is a required component in the Unipage system which serves to manipulate and review all of the system data contained in the Paging Terminal and Message Manager™. The Console provides pager and voice mailbox programming, database maintenance, system parameter setting, report generation capabilities, and "real time" system status.

The current release of software is Console 4. Console 4 is updated periodically to provide new features and functions for the Unipage system. The current version is 4.20. This section of the document is intended to provide a general overview of the Console 4 program. A complete overview of Console 4 is contained in the "Console 4 Reference Manual".

The Unipage Console program is customized software that provides the following general functions and features:

The Console program is menu driven which makes its operation very "user friendly". The starting point in the menu structure is the Main Menu. This menu provides the commands that the operator will use to perform the majority of the day-to-day operations for the system. It is also the central menu from which all other menus are accessed.

Each of the sub-menus provide a logical grouping of related functions within the Console. The two sub-menus below the Main Menu are the "Maintenance Menu" and the "Other Menu".

The Maintenance Menu contains one sub-menu, the "Modify Setup Menu". The Other Menu contains two sub-menus, the "Report Menu" and the "Account and Number Management Menu". Figure 8 provides an illustration of how the menus are arranged.


figure 8


5.2.1) Main Menu
The Main Menu of the Console provides 15 function options to control the Unipage system. These options, as displayed on the Console's VDT screen, are denoted by a letter or symbol followed by a brief description:

Commands "D" through "P" and "-" through "=" all perform functions directly related to programming a specific pager in the system. The brief descriptions provided with the commands are fairly self-explanatory. Commands "S" through "Q" either perform general system functions or guide the system operator into other areas of the Console program. The following are more detailed descriptions of several of the commands.

"S: Send System Setup Information" is a system function (versus a specific pager function) that allows the operator to send the system setup information to the Paging Terminal from the Console Computer, since all parameters in the Paging Terminal are duplicated in the Console Computer. If an operator installs new options, or the Paging Terminal loses power for an extended period, this command is used to update the Terminal.

"R: Reload Paging System Database" will reload the subscriber information from the hard disk of the Console Computer to the Paging Terminal. This option is used if the Paging Terminal loses its subscriber memory.

"L: Log to Another Database" allows the operator to access multiple databases contained within the Unipage system. Typically, an operator spends the majority of time in the "local" database which contains the local Terminal's subscriber records. However, the Console provides the ability to log into other "remote" databases. An example of a "remote" database is a Trunk Frame within a Multi-Frame system. A service operator can log into this Frame to modify operating parameters or display the status of inputs. Access to the databases is security code controlled.

As pointed out previously, the Main Menu also provides access to its two sub-menus through the "M: Maintenance Menu" and "O: Other Menu" options. These menus are discussed below.

5.2.2) Maintenance Menu
The Maintenance Menu is usually restricted to everyone except the Unipage system's technical support personnel. This Menu allows complete access to system files and statistics, including system parameter settings, call counts, and trunk statistics.

The Maintenance Menu provides 13 function options which are denoted by a letter or symbol, followed by a brief description:

The following is more detailed information on several of the options contained within this menu (an explanation of "M: Modify Parameter Files" is given below in section 5.2.3, "Modify Setup Menu").

The "R: Reload call Counts from disk" command is primarily used when a subscriber memory card in the Paging Terminal fails. When this situation occurs, a new MX series Card needs to be installed and reloaded with the subscriber record data contained in the Console. This command reloads the call count data that existed in the Paging Terminal prior to the failure.

The "V: Verify Unipage / disk data" command is used when there is concern that the data contained in the Paging Terminal is not the same as that found in the Console. Although this occurrence is very infrequent, this feature provides added security for the system's databases.

The "I: Regenerate Database Images" command is used to generate certain internal information within the Console database. This function is used after an "Extended Service Package" definition is changed. These packages are explained in section, "Package Service Information".

5.2.3) Modify Setup Menu
The Modify Setup Menu is accessed by implementing the "M: Modify parameter files" command in the Maintenance Menu. The Modify Setup Menu plays a vital role in the Unipage system and warrants its own section for explanation. The options within this menu allow the operator to define the system parameters for all three components in the system - the Console, Paging Terminal, and Message Manager™. The Console stores the operating parameters in parameter files on the Console's hard disk.

The command options are the following:

The following descriptions provide an overview for the above commands, with the exception of "A: Agent Passwords and Permits" and "P: Package Service Information" which are described in their own sections.

The "Channel Setup Information" and "Extended Setup Information" commands serve to define parameters for the operating characteristics of card components in the system. The Channel Setup consists of inputs for the Station ID, Station ID interval, voice page length, voice page storage count (maximum number of messages which can be stored for this channel), channel use limit (maximum number of seconds a channel can send pages without stopping), and mode delay (amount of time needed to switch from analog-to-digital or digital-to-analog paging). The Extended Setup provides commands for the trunk input programming, channel programming, customized processors, and TNPP Network Cards within the Terminal.

"Memory Mapping Information" is used to allocate the subscriber record memory contained in the system. Specifically, memory mapping establishes the relationship between the telephone number prefixes and the subscriber numbers within the system.

"Note Messages" are special messages that are used in conjunction with the Agent log-in process. The Notes field allows for the entry of up to six letters, each of which designates a note to be displayed to a particular agent upon logging into the Console program.

"System Setup Information" allows access to the system parameter file, which contains information about system operation. Specifically, parameters include call logging (Y/N), clock enabled (Y/N), disable auto upload (Y/N), print log to printer (Y/N), high speed console (Y/N), modem phone number, startup password, maintenance password, and modem password.

"Trunk Definitions" establishes the signaling characteristics for each trunk interface. The classifications include ring up, outdial, DID with pulsing, DID with DTMF or MF, and wink start.

"Unit Type Information" establishes all the pager types within the system, such as Numeric Golay, Alpha POCSAG, and 2-tone pagers. The Unipage system supports virtually all pager types utilized in the market today.

"Help Information File" allows the system maintenance operator to change any of the context sensitive help messages. The "on line help" file exists to assist operators when they encounter questions in programming pagers or system parameters. Agent Passwords and Permits
The Console provides multiple access levels to limit the access of selected users on the system. Since different users need varying levels of access, this feature provides security for the system's subscriber database and operating parameters. Specifically, there are five (5) levels of access:

Level 0 Access allows the Console user to view a pager record or to send a page from the Console keyboard. No manipulation of data is allowed.

Level 1 Access is for users who need to have access to a particular group of subscribers. This level allows programming within a particular account number range, channel code, and pager unit type.

Level 2 Access allows unrestricted access to subscriber record functions such as the ability to issue new service or cancel service to a pager. This level allows restricted access to the Other Menu and prohibits access to the Maintenance Menu where system parameters can be altered. Specifically, access to the Other Menu is limited to generating reports and utilizing the Console's dial-up modem (if available).

Level 3 Access allows unrestricted access to the subscriber record functions and the Other Menu. Access to the Maintenance Menu is still prohibited.

Level 4 Access allows full access to the Terminal, including subscriber record functions, the Other Menu, and the Maintenance Menu.

The access levels are also custom tailorable to provide even greater flexibility for the service provider. This enhanced feature is discussed in section, "Custom Access Levels". Package Service Information
Extended Service Packages are intended to simplify the pager programming process for the Console operator. The operator can create multiple Packages to meet the unique service needs of the subscriber base. These customized packages can set the Channel, Zone, and Control Flags used for a particular pager record (see section, "Flags Field" regarding Control Flags). The packages can also be used to define the customized greeting code and Message Manager™ control string which establishes the type of voice messaging service.

Packages can be created to define all aspects of a subscriber's voice messaging service. The categories are:

5.2.4) Other Menu
The Other Menu includes various commands such as account and number management, report menu, and backup and restore functions for the database. Access to the Other Menu is restricted based on the access level assigned to a user. The Other Menu provides nine (9) function options which are denoted by a letter or number, followed by a brief description:

The following are brief descriptions for several options within this menu, with the exception of options "A", "R", and "S" which are discussed in separate sections below.

"U: Utility Access" allows the Console operator to exit Console 4 to execute an Operating System Utility or Console Utility. When the operator has finished this task, he can reenter Console 4 without the need to log back on.

"D: Dial (modem)" allows the operator to dial a remote Paging Terminal via modem. The "H: Hangup (modem)" command goes hand-in-hand with the "D" command, since it disconnects the modem when the Console operator has completed communicating with the Remote Paging Terminal.

"1: Backup Unipage database" allows the operator to copy the Console database onto a floppy disk in a compressed format. "2: Restore Unipage database" allows the operator to copy the database information contained on the floppy disk back into the Console after a Console hard disk failure. The "2" command decompressed what had been compressed with the "1" command. Account and Number Management =
The "A: Account and Number Management" command provides the operator with the ability to manage groups of pagers or accounts with respect to Agents who are accessing the Unipage system. The Account and Number Management menu contains seven (7) options which are:

"A: Allocate phone numbers to accounts" allows the operator to assign a range of phone numbers to an account number. These numbers then become available to an operator with agent level access (Level 1, as discussed in section whose account range encompasses the assigned range. These numbers are also available to any operator whose access level is higher that agent level access (Level 1).

"R: Reallocate Phone Numbers/Accounts" allows numbers currently allocated to a specific account range to be reallocated to a new account number range.

"S: Suspend Pagers by Account" allows the operator to suspend a group of pagers based on the account number. In turn, the "U: Unsuspend Pagers by Account" allows the operator to reverse the "suspend" command.

"C: Create Phone Number Region" allows the operator to create a new range of pager telephone numbers, which must already exist in the Console's memory map. Up to 1000 numbers can be created at one time. "E: Erase Phone Number Region" is the opposite of the "C" command since it erases blocks of pager telephone numbers no longer in the system. Report Menu
The Report Menu provides information which is important to the management of the system. The Console contains 10 predetermined reports and also contains a versatile Extended Reporting Option which is discussed in section The 10 predetermined reports are the following (a brief explanation of each report is provided in parentheses):

N:Non-Vacant Subscriber Records
(Lists all active or inactive subscriber records in the system, skipping all vacant records)

V:Vacant Subscriber Records
(Lists all records available for assignment)

R:Range of Subscriber Numbers
(Lists all records within a requested range)

(Lists all records within a requested cap code range)

(Lists all records within a requested account number range)

(Lists all records containing specified flags within a requested range)

(Lists all records where the call count number exceeds a predetermined call count limit)

(Lists all records containing specified packages)

(Lists all records containing one or more Group Call ID numbers)

L: Last Modified
(Lists all records changed within a specified date range)

The service provider can modify the report format to display only those fields deemed as pertinent to a particular report. Once the field selections are made, the Console allows the report to be sent to a VDT or printer. The format to the printer can be set for 80 column or 132 column. The column widths of each field selected for the report can also be custom tailored. Status Display
The Status Display provides "real time" viewing for trunks, channels, and network connections in the system, as well as how many voice recorders for voice paging are in the system (the Quad Store Card described in section provides these voice recorders). It also shows the number of Expansion CPU's in the system. Expansion CPU's are defined as the Expansion Processor Card (EXP3) and Subscriber Memory Cards (the MX16, 32, and 64) as described in section 4.4, "Card Component Hardware".

The Status Display also provides a detailed breakdown for up to three (3) trunks in the system. This breakdown consists of nine (9) parameters which provide greater information to the system operator. Specifically, these categories are the following:

Trunk ID - The maximum number of trunks in a given Trunk Frame is 60, so the Trunk ID numbering is from 1 to 60. If more than one Trunk Frame exists in a system, then the Console can be configured to show the status display for each Trunk Frame in the system. This process is accomplished by adding a CRT/Keyboard Master Station (CKM) to switch from Frame to Frame for viewing. The CKM can view up to 15 different Frames within a Unipage system.

Status - The trunk status shows what a given trunk is doing at a given moment in time. Status messages include Idle, 1st...7th digit, Connect, Play Greeting, and Message Input. All of the trunk conditions are itemized is section, "Statistics Processor Card".

ValidLogs the number of valid calls for the trunk.

InvalidLogs the number of invalid calls for the trunk.

MinutesLogs the number of minutes the trunk has been used for call input.

ErrorLogs the number of errors detected on the trunk..

SubidShows the current Subscriber ID number that the trunk is handling.

UseShows the time for the current call in seconds.

MessageShows the current numeric message being entered by a caller into the system.

5.2.5) Console Subscriber Record Data Fields
The format of the Console program is based on the use of data fields. These fields serve to program a subscriber's paging and voice messaging service and to store information pertinent to the subscriber's account. The following are the data fields contained in the Console program: Channel Field
This field designates which RF paging frequency the pager is assigned to. The Console can be set to show the channel or network name or frequency to correspond with the letter (A-P) assigned to the pager (e.g. B = 152.840 MHz) Pager Type Field
This field refers to the signaling type of the pager. The Unipage Terminal supports virtually all formats including POCSAG 512, 1200, and 2400; Golay (GSC); and US 2-Tone and 5/6-Tone. FLEX will be supported when it is fully implemented in the market. Cap Code Field
This field contains the unique cap code number of the pager to differentiate it from all the other pagers on a particular RF paging channel. Pager Function Field
This field allows the alert tone for a pager to be set to one of four (4) different "beep" sequences. On display pagers, the function is also displayed on the pager typically using a letter (A-D). Not all pagers can be programmed with multiple addresses. Call Count Field
This field tracks the number of calls a pager receives, up to 55,000 calls. This field can also be programmed with a negative number which will suspend pager service when the call count hits zero. At zero, the word "suspended" appears in the field.

The Call Count field can also be set to count characters instead of calls. This feature is primarily used with alphanumeric pagers, where service charges are based on the number of characters received versus call count.

An enhanced feature, called "Expiry Feature", provides even greater versatility in tracking and controlling a subscriber's usage of the paging system. This feature is explained in section Last Count Field
This field contains the number of calls received since the last time the call count was extracted using the "Extract call counts from Unipage" function (explained in section 5.2.2, "Maintenance Menu"). This allows the service provider to periodically bill a subscriber on a call sensitive basis. Date In Service
This field provides an historical record of when the pager was first programmed into the Unipage system. Last Modified Field
This field displays the last date that the pager was modified. This information provides an historical record for the pager that is different than the "Date In Service" information described above. Notes Field
The Console provides a field to enter special notes unique to a particular subscriber which cannot be accommodated by any other field. Entries in this field can be used in the Extended Reporting Feature which is explained in section Zone Field
This field contains the "zone" information which determines the coverage area that a pager will have. By using a number between "0" and "15" to represent one of 16 coverage areas, the service provider can program a pager to operate in part or all of the RF paging network. Account Number Field
This field can contain a number which provides the Console subscriber record a corresponding account number for billing and reporting purposes. This field can contain up to seven (7) numeric digits. Flags Field
The Console uses a "flag" to provide additional functionality to a given pager. A flag is simply a letter or number which represents a particular pager condition such as the status or level of service. This field can contain up to eight (8) flags, all of which are independent of one another. There are three (3) types of flags - inactive, information, and control:

Inactive Flags - There are four (4) letter options, A-D, which can be used. All options will make the pager inactive. Each letter can be set to represent a different reason as to why the pager is inactive (e.g. "non- pay" or "lost unit").

Information Flags - There are four (4) letter options, E-H, which have no impact on the pager programming. These flags are set with any meaning the service provider chooses, and are simply used to mark records for reporting purposes.

Control Flags - These flags use distinct letters which have distinct meanings when they are set. The letters are:

"R" for "Report"
"L" for "Live"
"P" for "Priority"
"X" for "eXtra Service"

Specifically, "R" prints all calls received by a particular subscriber to a logging printer; "L" send all voice pages directly to the channel output, bypassing voice storage; "P" allows the page to go to the front of the page encoder queue; and "X" generates a repeat page to be sent to the subscriber. Group ID Field
This field is used to set "group calls" for both sequential group paging or with the Group Processor (GP) Card (refer to section 4.4.5, "Optional Cards", for a description of the GP Card). This field allows multiple pagers to be programmed to a group, with one pager serving as the "master" group telephone number. Serial Number Field
This field can contain the serial number of the pager for increased tracking purposes. This field can also contain other numbers designated by the service provider to track pagers. Extended Services Field
This field contains the tailorable service packages that the service provider establishes in the system. An example is a voice messaging package which contains a 10 second personal greeting, 30 second mailbox, and numeric page notification when a message is deposited. The service provider can create multiple packages to meet the service needs of the market.

5.2.6) Enhanced Console Features
The Console 4 software has recently been enhanced to provide additional features for the service provider. These features greatly improve the flexibility and functionality of the Console program, allowing for better management of the Unipage system. These features come standard with all Unipage systems. Extended Reporting Capability
Console 4 has the ability to allow the service provider to custom tailor reports which search on multiple criteria, including combinations of fields in the database and fields with specific contents. This feature allows reports to search on "and/or" criteria, on criteria within a certain range, and even on information contained in the "Notes" field.

The customized report templates that the service provider creates can be saved, eliminating the need to remake a specific report template each time it is needed. Custom Access Levels
Along with the five (5) standard access levels, Console 4 allows customized access levels on a "per user" basis to be created. Specifically, this enhanced feature allows the service provider to choose what commands a user can have access to, such as the "M: Maintenance Menu". This feature is used when the standard access levels do not match the levels the service provider needs to establish for its users. The customized access levels can be modified at any time. Remote Database Capability
Console 4 has the ability to access database information on a remotely located database via TNPP link. This means that a Console in City A can display or modify a pager record that resides on a Console in City B using a TNPP network connection. This allows Console users in one city to perform network-wide changes for subscribers in any other city. Expiry Feature
The Console provides the capability to automatically suspend a subscriber's paging service on a specified date by entering this date in the "Expiration Date" field. The "Expiration Date" field replaces the "Date in Service" field when this feature is activated.

This feature provides a major benefit to service providers who charge a fixed rate for a given period of service, such as one month. When the expiration date entered in the "Expiration Date" field approaches, the Console will initiate a "warning" page to the subscriber indicating service will soon be suspended. If the subscriber does not renew the service, the Console will initiate a "service termination" page to the subscriber indicating that service has been suspended. The Console then automatically "deactivates" the pager record. Range Test Function
Console 4 provides the ability to page up to 20 pagers at a specified time interval. Every page contains a time stamp and a sequence number to verify sequential receipt of pages. Fast Reload Capability
Console 4 fully utilizes the capability of the Fast Load (FL) Cards (refer to section, "Fast Load Card (FL)", for a detailed description). This capability increases the reload speed of the database from 9600 baud to 38.4KB, a four-fold improvement. Test Page Priority Control
This enhancement allows the service provider to choose if a test page sent from the Console keyboard has priority or not. Previously, all pages sent from the Console had priority status, which presented problems for some service providers. Now this priority is an option. Improved Backup
Backup diskettes are now automatically formatted prior to their use when backing up the Console database. Also, the ability of the program to perform a backup without affecting other users of the system has been improved. Undelete Capability
The maintenance operator has the ability to "undelete" numbers that have been inadvertently removed from the database. This step must be performed prior to a "pack" being performed, since this process makes all changes to the database permanent. The "pack" function is located in the Maintenance Menu under the command "::: pack database file after # erase". Index Integrity Checking
The Console program has the ability to perform additional index integrity checking by comparing the date of the database file to the date of the index files during startup. If the dates do not match (indicating indices are out of sync with the database) the program will automatically update the index files. This process will help prevent problems for customers who move their databases from one computer to another.

5.3) Message Manager™ Features
The Message Manager™ provides custom greetings, numeric page insurance, voice page insurance, and voice messaging features for the Unipage system. The following is a list of features that are standard in the Message Manager™.

5.3.1 Subscriber Features
Subscriber features are defined as those which provide voice messaging functionality to basic paging service. These features differ from administrative features (discussed in section 5.3.2) which allow the service provider to set mailbox parameters and to better manage the Message Manager™ system. Voice Mailbox
Any subscriber can be assigned a voice mailbox on the Message Manager™ system. This mailbox allows callers to deposit a message for the subscriber for later retrieval. The caller simply dials the subscriber's mailbox telephone number and receives prompting on how to leave a message. Customized Mailbox Greetings
The Message Manager™ provides various levels of prompting to assist the caller in leaving a message for the subscriber. Prompting can range from "Shared" to "Custom" depending on how the subscriber's mailbox is programmed.

The Unipage system provides 24 semi-custom voice prompts selectable via the greeting code in the Message Manager™ record. There are also 60 prompts which are selectable using packages (as described in section, "Extended Services Field"). There are also eight (8) prompts available to replace the VP8 announcements if the VP8 Card is not used.

A Shared Greeting mixes the general Message Manager™ system prompts with customized inserts. This level of prompting provides some personalization without utilizing much space on the Message Manager™ hard disk. Inserts can either be a Name or Number, as described below:

Name Insert - This type of shared greeting provides a general prompt similar to "Please leave your message for...", followed by a custom insert which allows the subscriber to personally record his name.

Number Insert - This type of shared greeting provides a general prompt similar to "Please leave your message for...", followed by the subscriber's pager number. The voice for the pager number insert is generated by the Message Manager™ and not recorded by the subscriber.

A Custom Greeting allows the subscriber to record a personalized message to greet callers. This type of greeting provides the highest level of personalization and functionality, but also uses the most Message Manager™ hard disk space.

Both shared and custom greeting lengths are programmable on a per subscriber basis. Greeting lengths start at 10 seconds and go to 90 seconds in 10 second intervals. The Message Manager™ can be programmed with no greeting (simply a beep tone prompt) or with a 10 minute greeting for applications that require these options. Pager Notification after Voice Message Deposit
A major benefit of Unipage's integrated paging and voice messaging system is the ability to notify the subscriber that a voice message has been deposited in his mailbox. This notification can be set to work with any digital pager. A numeric pager will indicate the mailbox telephone number, and an alphanumeric pager will indicate the mailbox number followed by the text, "Message Waiting". Reminder Page
The voice mailbox can be programmed to send up to nine (9) reminder pages to notify a subscriber that a voice message is waiting in the mailbox. The time interval between pages is also programmable. This feature is useful for subscribers who cannot immediately respond, or may have missed one or more pages for any reason, such as being out of the coverage area. Numeric Page Insurance
The Message Manager™ provides numeric page insurance for numeric display paging subscribers, in the event a page is missed or deleted from the pager's memory. The Message Manager™ converts the DTMF numeric message to voice and plays it back to the subscriber when he accesses his mailbox. Voice Page Insurance
The Message Manager™ provides voice page insurance for voice paging subscribers. With this feature, a caller records the message to be sent as a voice page to the subscriber's mailbox (as opposed to using a Quad Store Card as described in section The Message Manager™ then sends the message to the channel output to be broadcast over the RF paging network. After receipt of the voice page, the subscriber can review the message which is still being stored in his mailbox. Voice Message Deposited and Page Sent in Same Call
This feature allows a caller to leave a voice message in the subscriber's mailbox, and send a numeric page via DTMF telephone in a single call to the Unipage system. If a caller performs this option, the subscriber will receive a numeric page, and a second page that indicates a voice message is waiting in the mailbox.

If a caller simply leaves a voice message or immediately enters a numeric page via DTMF telephone, the subscriber will only receive one page (a "message waiting" page, or the numeric page entered, respectively). The Unipage system allows for a two (2) second hesitation in entering a DTMF message. If for whatever reason a caller is slow in entering digits, the Unipage will ignore any voice recording unless it exceeds the two second limit. This feature reduces the number of unneeded pages sent to the subscriber. Number Change Notification
A voice mailbox can be programmed to provide callers information on a subscriber's new telephone number in the event that the number has been changed. This feature is useful when subscriber numbers need to be changed for whatever reason, such as number block consolidation. Prompt Override
The Message Manager™ allows a caller to override the greeting that is being played by simply hitting a DTMF key on the telephone. This allows both experienced callers and subscribers to save time in accessing the Message Manager™. If a caller wishes to leave a voice message, the greeting cannot be overridden. Telephone line levels can affect the performance of this override feature. LIFO/FIFO Retrieval
The Message Manager™ allows the subscriber to retrieve messages on a "last in, first out" (LIFO) or "first in, first out" (FIFO) basis. "Help" Menu
The Message Manager™ contains an On-line Help file which can assist users who are not familiar with the Message Manager™ commands. By simply hitting the proper DTMF key, a caller receives instructions which provide more in-depth instructions on how to utilize the Message Manager™ commands. Subscriber Changeable Security Codes
Each mailbox is security code protected, so the subscriber must enter a personalized security code to retrieve messages. This code can be changed by the subscriber at any time. When the mailbox is established, a default security code (the number "100") is used until the subscriber goes in and changes it. The security code can be up to six (6) digits in length. The maximum number of digits is programmable for either four (4) or six (6) digits, depending on the service provider's preference.

5.3.2) System Administration Features
These features are designed to aid the service provider in managing the Message Manager™. Typically, these features set voice mailbox parameters or allow for tracking of system information such as call logging. Number of Messages
The maximum number of messages allowed per mailbox can be set from one to 40 on a per subscriber basis. Message Discard
The Message Manager™ provides notification to the subscriber when messages are deleted from storage. Typically messages are deleted because they have exceeded the maximum allowable storage time established by the service provider. Hard Disk Auto Push
To ensure that the hard disk always has enough capacity to accommodate new messages into the system, the Message Manager™ will automatically delete the oldest messages on the disk to make room for new messages. This deletion only occurs when the hard disk approaches full capacity. Without this feature, depositing of new voice messages would stop until room became available on the Message Manager™ hard disk.

5.3.3) Enhanced Subscriber Features
The following features come standard with the Message Manager™ and can be used by the service provider who wishes to offer more sophisticated voice messaging features to the market. Automated Attendant
This feature allows multiple voice mailboxes to be configured together for advanced messaging applications. With Automated Attendant, the caller is instructed via custom greeting to choose whom to leave a message for. Using a DTMF telephone, the caller selects the voice mailbox he wishes to access, and leaves a message for the appropriate subscriber. An example of an Automated Attendant mailbox is, "Hello. Please press '1' to leave a message for Accounting, '2' for Sales, and '3' for Engineering". By entering one of the numbers, a caller is directed to the voice mailbox of the appropriate department. The voice mailbox for each respective department also provides a personalized greeting, such as, "Thank you for calling the Sales Department. Please leave your message after the tone."

Automated Attendant also provides message transfer capability. If a caller does not know the extension or mailbox number of the subscriber they wish to reach, he can record a message in the main Automated Attendant mailbox. The subscriber can then transfer the message to the appropriate mailbox by using a DTMF telephone. Message Transfer
This feature allows the subscriber to transfer a voice message to another voice mailbox. This feature does not provide append capability. Distribution List
Each mailbox can contain one (1) distribution list which can contain up to 9,999 mailbox addresses. This feature allows a single voice message to be automatically distributed to all the mailboxes in the distribution list. "On Call To" Mailbox
This feature allows all calls going to a particular mailbox to be redirected to another mailbox in the event the subscriber cannot retrieve his messages. This feature is activated by the service provider at the subscriber's request. Notification Cascading
This feature provides the ability to have multiple pagers notified in sequence when a message is deposited in the mailbox. To provide cascading, the Message Manager™ searches the pre-arranged notification cascading list to determine where to route the voice message. The Message Manager™ then deposits the message in the appropriate mailbox, which in turn sends a notification page to the subscriber who possesses it. If this subscriber does not retrieve the message by the first reminder page, the message is deposited in the second mailbox on the list. If all the subscribers on the list are notified but do not retrieve the message, the message is stored in the first mailbox for future review.

5.3.4) Alpha Transcription
Alpha Transcription (AT) is a feature which allows a caller to leave a message in a subscriber's mailbox, and have this message forwarded to a live operator. This operator then "transcribes" the message into an alphanumeric page to be sent out over the RF paging network.

In order to accomplish this task, the Unipage system uses Message Manager™, an AT Card Set located in the Paging Terminal, and a VDT with headset and keyboard. When a caller calls into the system, the message is stored on the Message Manager™ hard drive just like a normal voice message. However, once the message is stored on disk, notification that a message is waiting is sent to the operator's VDT through the AT Card Set. Specifically, the VDT beeps and displays the text message, "Message Waiting".

The operator retrieves the message by hitting the "Enter" key on the keyboard. The message is played via headset from the Message Manager™ hard disk. As the message is being played, the operator transcribes it at the VDT. The operator can stop or replay the message at any time by using "function" keys on the VDT keyboard.

After being entered into the Paging Terminal, the transcribed voice message is sent to the subscriber as an alphanumeric page. Because the voice message is still stored on the Message Manager™ hard disk, the subscriber still has the option to retrieve it from his mailbox. Alpha Transcription Function Keys
Alpha Transcription provides the following function keys for an operator inputting messages:

F1 -Replay message from Message Manager™
F2 -Send partial message with identifier for unclear parts of the message
F3 -Send message to subscriber that message is not understandable
F4 -Send page
F5 -Replay last three seconds of message
F6 -Stop/Start message Alpha Transcription Prompts and Commands
The Alpha Transcription VDT screen displays either a "Waiting for Message" prompt, or a "Message Waiting - press Enter to connect" prompt to indicate a message is in queue. The screen also contains the prompts "Press 'P' to send page" and "Press 'N' for automatic verification mode".

Under normal operation, the operator waits until the "Message Waiting" prompt appears on the screen, and hits the "Enter" key to display the subscriber's Pager ID number. The operator then simply needs to transcribe the message which is played from the Message Manager™ hard disk, and hit "F4" to send the message.

The "P" command allows the operator to send a message to any subscriber in the system at any time. After "P" is entered, the operator will be prompted to manually enter a Pager ID number. After entering this number, the operator can enter a message and send it by hitting "F4".

The "N" command provides a canned message which can be sent to alpha pagers when an operator is not on duty. The message consists of the Pager ID number (which is the mailbox telephone number) followed by the text message, "Message Waiting". This feature is beneficial if operator service is, for example, during business hours only.

Functions "F2" and "F3" described earlier require a bit more explanation. "F2" is used if a portion of the voice message is not understandable. Using this function inserts "??????" into the message being sent to the pager. "F3" creates the canned message "Cannot translate message, please retrieve by phone" and is only used when most of the message cannot be understood.

Alpha Transcription has the ability to store up to 18 canned messages which are accessed by using the function keys. Specifically, the service provider can create canned messages such as "Emergency, please retrieve message immediately" and assign these messages to the function keys F7 - F12, and Shift+F1 - Shift+F12.

The Unipage system is very versatile in its ability to provide various levels of redundancy. You can configure your system to meet your immediate redundancy requirements based on the amount of capital you wish to invest. You can then increase the level of redundancy as the need for greater system redundancy arises. Redundancy in the Unipage system follows the same "modular" approach as discussed in section 4, "Unipage Hardware Architecture".

6.1) Redundant Switches
The Unipage Redundant Switch is a rackmounted Panel which only uses 1.75 inches of vertical cabinet space. Depending on the size of the system and what components in the system are made redundant, there typically will be several Redundant Switches utilized.

The Redundant Switch Panel (RS Panel) provides automatic switchover to the "secondary" system side in the event of a failure of any component in the "primary" side of the system.

Redundant Switch Link Cards (RS Cards), which are explained in section, provide the communications link between each side of the system. An RS Card is located in the "primary" side of the Paging Terminal, and one is located in the "secondary" side. Since each RS Card contains two ports, one port is connected to the RS Panel and the other port is directly connected to the RS Card on the opposite side. The direct card-to-card connection serves to keep the "secondary" side current with the "primary" side. The port connections to the RS Panel itself serve to switch the system to the "secondary" side in the event of a failure.

There are several types of RS Panels that perform different switching functions. These Panels can be used in both Single-Frame and Multi-Frame systems, depending on the configuration. These switches are discussed below.

6.1.1) Redundant Switch for Model 15 (RSM15)
This RS Panel provides switchover for a Model 15 Paging Terminal which has standard chassis wiring (eight trunk slots and one channel). For Single-Frame Model 15 systems, this switch will perform all the necessary connections to provide full redundancy.

If the chassis has optional wiring such as additional channels or additional trunks beyond the standard configuration, then different types of RS Panels may be needed to provide connections for all the card components.

If additional standard 15-slot chassis are added to the Model 15 Paging Terminal, additional RS Panels will be needed for each chassis that is added. For example, if two chassis with standard wiring are configured together to form a Model 30, then two RS15 Panels would be required. Three chassis would require three panels, and so on.

6.1.2) Trunk Expansion Switch Unit (RSTK)
This RS Panel provides switchover for an analog (TK and TK2 Cards) Trunk Frame. Just as with the RSM15, the RSTK is designed to automatically switch an analog Trunk Frame from the "primary" side to the "secondary" side in the event of failure. If analog trunk input redundancy is required, each "primary" Trunk Frame in the system requires one RSTK.

6.1.3) Data Expansion Switch Unit (RSDX)
This RS Panel provides switchover for up to six (6) RS-232 serial port connections per chassis. If a chassis utilizes more than six dual serial ports, then an additional RSDX is used for the next six dual port connections. Since all Unipage cards that utilize serial port connections have two ports per card, an RSDX typically provides switchover for three (3) slots in the chassis. Several cards that would use this Panel are the TNPP Network (NW), Expansion Processor (EXP3), and Telocator Alpha Protocol (TAP).

6.1.4) Channel Expansion Switch Unit (RSCH)
This RS Panel provides switchover for up to three (3) Channel Sets per chassis. This particular switch is "non-voting", meaning that in the event of a failure, the RS Panel will not process any pages that may be in queue in the "primary" side Channel Sets before switchover.

6.1.5) Channel (Voting) Expansion Switch Unit (RSCV)
This RS Panel is identical to the RSCH but provides limited "voting", or page in queue drain off, after it switches to the "secondary" side of the redundant system. This prevents the pages in queue from being lost in the event of a failure.

The Unipage architecture provides a system capacity that is unequaled in the paging industry. The Unipage system derives its high capacity from its multi-processor architecture, which is simply not found in Paging Terminals that utilize a less advanced "single-processor" or "co-processor" design.

Motorola defines a "multi-processor system" as one where the tasks required of the system are efficiently divided between multiple processors. As the Unipage system expands, the number of processors is increased to handle the increased processing requirements of the system.

A particular processor's tasks are carefully selected to minimize the amount of data that must be exchanged from processor to processor. This careful division minimizes the amount of data that must be carried over Unipage's "X-bus", therefore minimizing the burden on the "central" Main Processor that serves to coordinate this "X-bus" activity. What this means for the Unipage system is that the dependence on the processing capability of a single central processor is minimized.

In contrast, "single" and "co-processor" systems utilize one (1) high capacity, central processor to handle all of the tasks for the entire system. Although a "co-processor" system does utilize additional processors to handle specific tasks, such a design is typically an outgrowth of a single processor design that has reached its limits. The additional processors serve to off-load limited tasks, relieving only a portion of the burden from the central processor. Such a co-processor architecture still heavily depends on the single, central processor to handle the bulk of the system's tasks and has a limit to its expansion capability.

The Unipage system was designed from the very start with a multi-processor architecture. Low cost 8-bit and 16-bit processors still provide unequaled processing capability for all of the Unipage systems installed around the world today. This includes systems which are capable of handling hundreds of thousands of subscribers and use high speed paging encoding formats such as 2400 baud POCSAG.

As system processing requirements increase, the Unipage system is well positioned with its multi-processor architecture to be easily upgraded to handle these requirements. The ease of upgrading a Unipage system is discussed in section 8, "System Upgrade Paths".

7.1) Main Processing Capability
Both the standard and high speed Main Processor Cards coordinate the data exchange between the numerous processors in the system. The standard Main can process 11 pages per second, which is more than sufficient to handle the vast majority of system requirements in the Americas.

If Motorola determines that the high speed Main Processor is needed in a system, this card can process 45 pages per second (assuming a 10 digit numeric, or TNPP ID Page).

7.1.1) Standard Main Processor (MA3) Capability
When placed in the Main Frame of a system, this Main Processor Card can process 11 pages per second. This processing rate, multiplied by 3600 seconds per hour, equates to a maximum of 39,600 total subscribers on a system. Since not every subscriber receives a page in a given hour, this number must be divided by the "busy hour call rate" (BHCR) percentage. The following chart provides the maximum subscriber capacities for three BHCR's - 20, 40, and 60%:

# pages/sec BHCR Total # Subscribers
11 60% 66,000
11 40% 99,000
11 20% 198,000

When the combination of total subscribers and "Busy Hour Call Rate" (BHCR) percentage exceeds the MA3 Card's capabilities, it is a very simple task to migrate up to the high speed MAX Card.

7.1.2) High Speed Main Processor (MAX) Capability
The MAX Card can process 45 pages per second, which equates to a maximum of 162,000 pages per hour (assuming a 100% BHCR). The following chart shows the capability of the MAX with BHCR's ranging from 20-60%:

# pages/sec BHCR Total # Subscribers
45 60% 270,000
45 40% 405,000
45 20% 810,000

7.2) Channel Encoding Capability
The standard Unipage channel encoder (the CH Card Set detailed in section 4.4.3) can handle the majority of paging applications found in the market today. For systems that utilize high speed encoding and/or provide high character length alphanumeric services, Motorola has available a high capacity channel encoder which provides additional processing capability and buffer capacity.

Each CH Card Set in a Unipage system contains its own processor and non-volatile memory. Therefore, as additional channels are added, so too are additional processors and memory.

7.2.1) High Capacity Channel Encoder (CHX) Capability
The CHX exceeds all encoding and buffer requirements found in the market today, including 2400 Baud POCSAG and high character length alphanumeric paging and data services. Since the output from the channel encoder is "fixed" at a particular data rate (e.g. 2400 Baud POCSAG), the primary tasks of the channel processor are to keep pace with the rate of output and to provide buffer storage for all pages that must wait in queue before being encoded.

The CHX provides a total buffer capacity of 256KB, up from 18KB in the standard channel set. This capacity allows the CHX to store approximately 11,000 pages in queue (assuming a 10 digit numeric page).

7.3) Trunk Call Processing Capability
Each Trunk Frame supports one T1 or E1 (CEPT) digital span, which is 24 or 30 trunks, respectively. Each Trunk Frame has its own self-contained "X-bus" and contains an 8-bit supervisory processor and an 8-bit communications processor. Each Frame accesses a centralized database via RS-232 link to the system's Main Frame. All subscriber record retrieval and non-voice call passing occurs over this data link at speeds from 9.6K to 38.4K Baud. Each call processed by a Trunk Frame requires only two (2) transactions with the Main Processor in the Main Frame - one to retrieve the subscriber record and one to pass the page message back to the Main Frame for processing.

As the number of trunks in a system is expanded and Trunk Frames are added, more processing power is automatically added to support the expansion. Furthermore, the data link between each Trunk Frame and the Main Frame can support up to 64 calls per second at 38.4K Baud, far in excess of the speed needed for even two T1 or E1 spans (48 or 60 trunks, respectively). The number of Trunk Frames supported is limited only by the transaction processing capacity of the "central" Main Processor, which is discussed above in section 7.1, "Main Processing Capability".

7.4) Message Manager™ Capability
The MM unit (as defined in section 4.2, "Message Manager Hardware") consists of one (1) 80486 processor for call control and four (4) 80188 processors for voice data handling. Since an MM unit is added for each Trunk Frame in the system, the number of processors increases with each MM unit.

7.5) Console Computer Capability
One of the most unique architectural aspects of the Unipage system is that the database management function is completely independent from the call processing function of the Paging Terminal. In most other Paging Terminals, the burden of database management is placed on the same central processor that is used to handle the paging traffic on the system. This means that the most vital and limiting resource in the system, call processing CPU time, must be shared for database functions.

Because the Unipage Console Computer is separate, it is not a "closed architecture" computer which does not provide direct access to outside applications. Since the Console is an IBM-compatible PC which runs on either DOS or a DOS-compatible multi-tasking operating system, it provides easy and "open" access to external database management programs. The subscriber record format is compatible with DBase III or IV®. This allows the service provider to purchase "off the shelf" DBase reporting software to provide complex customized reporting capability.

Depending on the number of users that require access to the Console Computer, the computer can easily be equipped with an 80486DX processor.

An important aspect of any paging system is its ability to be upgraded as the system expands or new innovations are introduced. If a system is not designed for upgradeability, its long term viability is in jeopardy. Even if a system's features and capacity meet the current needs of the market, rapid changes in encoding speeds, pager applications, and subscriber capacity can force a system to be prematurely obsolete.

This section addresses this topic of upgradeability, and points out the versatility of the Unipage system to expand with ease and without fear of obsolescence.

8.1) Main Processor Upgrading
In extremely large systems, it may eventually be necessary to upgrade the Main Processor Card to keep pace with subscriber growth. Although the subscriber capability of the standard Main Processor can be well over one hundred thousand, the ability to upgrade the main CPU is a vital part of any system's expandability. The Unipage system allows the CPU to be replaced easily and cost-effectively.

Upgrading to a higher capacity Main Processor is almost as simple as sliding out the current Main Processor Card and sliding a new one in its place. Specifically, the service provider takes the existing Card out of its slot, places a new Main Processor Card in the vacant slot, and updates the system parameters to the Paging Terminal from the Console Computer.

In a non-redundant system, service will be interrupted for several minutes during this process. However, if the system has a redundant Main Frame, paging traffic is not interrupted whatsoever. With redundancy, the service provider can manually switch all paging traffic to the "secondary" side of the Terminal prior to replacing the old Main Processor. Once the Main is replaced, the service provider can place the traffic back on the "primary" side. The Main Processor on the "secondary" side can then be replaced, again without impacting service.

It is important to note that the Unipage system only requires a Main Processor Card upgrade for the Main Frame of the Terminal. The Main Processor Cards which are located in secondary Frames, such as Trunk and Channel Frames, will not require the additional "horsepower" beyond the standard MA3 Card. However, if a faster processor is needed in future applications, these Main Processors can be upgraded by following the general procedure described above for the Main Frame's Main Processor Card.

8.2) Channel Processor Upgrading
With the advent of faster paging formats and increased alphanumeric and data usage on paging networks, the processing and data storage requirements for the channel output have increased. The Unipage system currently provides a Channel Set which can effectively handle 2400 baud POCSAG with high character alphanumeric paging.

Motorola currently is developing the ability to fully support all speeds of FLEX (1600, 3200, and 6400 baud). Details of this development will become more clear in the very near future.

8.3) Addition of Trunk Frames
The Unipage system is configured at the time of the original purchase to handle a particular subscriber load. As the system grows, the number of trunk inputs will need to keep pace in order to maintain an acceptable level of service. Again, because of Unipage's multi-processor architecture, the addition of trunks is as easy as adding more Trunk Frames to the current system. Since each Trunk Frame is its own self-contained unit, no changes are needed to existing Frames when additional Trunk Frames are added.

8.4) Addition of Voice Messaging Capacity
For each Trunk Frame added to the system that provides voice messaging service, a Message Manager™ LAN (MMLAN) unit must be added to the Trunk Frame. The addition of this MMLAN unit increases voice messaging processing capability for the Frame by adding an 80486 for call control, and four 80188's for voice data handling. The addition of these processors is sufficient to handle the voice processing requirements of each additional Trunk Frame.

The hard disk capacity for the Message Manager™ can be increased, regardless of whether or not the system is a Single-Frame or Multi-Frame. Smaller hard drives can be replaced by larger drives to increase voice storage capacity. In many applications, additional drives can be added together in parallel to increase capacity.

Motorola now utilizes 3.5 inch (approximately 8.9 cm) hard drives for many applications. These smaller drives can provide high capacity storage and eliminate the need for the Hard Drive Box. Systems that are built with 5.25 inch (approximately 13.3 cm) hard drives with a Hard Drive Box can either be expanded by adding additional 5.25 inch hard drives, or converted over to the 3.5 inch drives if they are available. The details of such an expansion will be evaluated by your Motorola Representative when the time comes to expand.

8.5) Addition of TNPP Networking Connections
If additional TNPP connections are needed, a TNPP Network (NW) Card can be added to provide two additional ports per card. If more than four full-routing TNPP connections are needed in a system, Motorola's system engineers can work with you to provide a networking solution.

8.6) Addition of Channel Frames
In systems with fewer than several channels, the Channel Sets (CH or CHX) are typically housed in the Main Frame. However, as a system grows, it is more efficient to break the Channel Sets out of the Main Frame and configure them in their own special Frame, called a Channel Frame. A Channel Frame is similar to a Trunk Frame in that Cards are housed in a 15-slot chassis which contains its own Main Processor Card.

Channel Sets that reside in the Main Frame can be configured into a Channel Frame by adding a 15-slot chassis, Main Processor Card, and Tandem Link (TL) Card. The chassis requires special wiring to accommodate up to six (6) channels per chassis, which simply needs to be specified at the time of the order.

To upgrade to a Channel Frame, the existing Channel Sets that are currently in use can continue to be used. For each additional channel output added, there needs to be one additional Channel Set. If more than six channels are contained in a Channel Frame, then another 15-slot chassis (without a Main Processor or TL Card) needs to be added to the first chassis, expanding the total Channel Frame capacity to 12 channels.

8.7) Addition of Subscriber Memory
Since the subscriber record memory in the Unipage Terminal resides on firmware contained on the Card Component itself, adding memory is as simple as adding additional Memory Cards (MX16, 32, and 64). Adding Memory Cards has a cumulative effect in that each card adds to the total amount of memory already present. For example, a system with 64,000 records can be increased to 128,000 by the addition of an MX64 Card.

The standard Unipage Console can accommodate up to 256,000 subscribers. 256K is achieved by using four MX64's in parallel. When the subscriber capacity of the Unipage system is expanded to 512,000 in the second half of 1994, the Unipage system will likely use a total of eight (8) MX64 Cards to provide the needed memory.

8.8) Addition of Main Frame Redundancy in a T1 or E1 (CEPT) System
The most common and cost effective method of redundancy is to make the Main Frame of the system redundant. Since the Main Frame of the system contains the vital components such as main processor and subscriber memory, a failure of any of these cards results in down-time for the system. Since there are typically multiple Trunk Frames in a Multi-Frame system, the failure even of an entire Trunk Frame will not completely disrupt automatic paging service.

To make the Main Frame redundant requires the duplication of all the Main Frame components, including one or more 15-slot chassis. In order to connect the "primary" Main Frame with the new "secondary" Frame, the service provider will need one or more low-cost Redundant Switches and two Redundant Switch (RS) Link Cards. The number of redundant switches depends on the Main Frame's configuration, but typically two to three switches will support all of the Main Frame connections. A detailed description of the redundant switches is given in section 6, "Redundant Operation". The RS Link Cards are discussed in section

Service is not interrupted while the redundant equipment is being installed.

8.9) Full Unipage System Redundancy
When analog trunks are used, the Unipage system is capable of full redundancy, including the Trunk Frames. The number of Redundant Switches depends on the size and configuration of the system. However, one (1) Trunk Expansion Switch unit (RSTK) is used for each Trunk Frame in the system.

8.10) Console Computer Upgrading
The Unipage system can utilize a wide range of Console Computers from the basic single-user Console to a 25-user Console with remote maintenance modem and BIO serial port for billing system interfacing.

If a larger Console is required, the existing Console is simply exchanged for a new model. Exchanging the Console results in less down-time since no component replacement needs to take place in the field. The database can be saved from the existing Console and reloaded into the new one.

It is important to note that since the Paging Terminal and Message Manager™ run independently of the Console, there is no down-time for these vital components during an upgrade. The only functions disrupted are those involving the Console such as subscriber record modification, parameter setting, and Console maintenance functions.

The Unipage system provides two qualities not easily found in other Paging Terminals - ease of maintenance and "hot" card replacement. These features result from the 15-slot chassis architecture combined with innovative design of the card components themselves. These features will save valuable maintenance time and provide fewer service interruptions versus systems that do not provide these features.

9.1) Ease of Maintenance
The 15-slot chassis architecture of the Unipage system is unique in the paging industry. The card components can easily be removed from the chassis without the use of a screwdriver or other tools. This design is in contrast to other systems that may have card components screwed into the chassis or connected with cabling that must be removed.

When a Unipage card component fails, it can be unlatched simply by hand and taken out of the slot. The latch requires only one motion to secure it or release it from the chassis frame. Once the card is removed, a new card can take its place in the newly vacant slot and be latched into place. All the card components within the Paging Terminal, including the Main Processor, Channel Controller, and Trunk Interface Cards, operate in this manner since the dimensions and latch design of the cards are all identical.

9.2) "Hot" Card Replacement
Through a special design on the card component itself, the Unipage Paging Terminal allows the replacement of all card components without having to power down the system. This feature is very useful since many card failures have limited or no impact on the basic operation of the Paging Terminal.

What this means for the service provider is that for many card failures, the Unipage system does not force a complete interruption in service to replace a non-vital component in the Paging Terminal. The working parts of the system can continue to work since the power is still "on".

Several types of cards that can fail without necessarily causing a complete interruption in service are the Trunk Interface, Voice Prompt, and special function cards, depending on the configuration of the system.

Even with vital components such as the Main Processor, Channel Output, and TNPP Network Cards, "hot" card replacement minimizes the time required to restore service to the Terminal. For example, if the Main Processor Card fails, power can remain "on" as the defective card is taken out and replaced with a new card. When the new card is installed, system parameters are resent to the Terminal from the Console Computer, and service is restored in minutes.

Without "hot" card replacement and without slide-in card components, the Main Processor Card replacement described above would likely require the service provider to 1) power down the system, 2) replace the "mother board" of the system that contains the main CPU, and 3) repower the system to restore service.

This section will provide general information on system dimensions and power consumption of the primary components that make up a system. With assistance from Motorola System Engineering, the service provider will be able to generally calculate the space and power requirements for each Paging Terminal configured.

10.1) Component Dimensions
The components of the Unipage system are housed in various chassis which are rackmounted into a Unipage system cabinet. These components have been discussed throughout this document - in particular the chassis for the Message Manager™ (both the standard unit and the LAN unit), File Server, Console Computer, and of course the 15-slot chassis which is the "heart" of the Unipage Paging Terminal.

Regarding cabinets, although most systems for Asia are mounted in one or more full-sized floor standing (CB3) cabinets, there are two smaller cabinets available.

The following data are the general dimensions for each component and cabinet. Metric dimensions are approximate and rounded off to the nearest tenth:

Unipage Component (cm) (in)
  H W D H W D
Large Floor Standing (CB3) Cabinet 185.4 61.0 81.3 73 24 32
Usable Vertical Rack Space 146.7 ---- ---- 57.75 ---- ----
Med Floor Standing (CB2) Cabinet 76.2 55.9 81.3 30 22 32
Table Top Cabinet 25.4 53.3 53.3 10 21 21
15-slot Chassis 13.3 48.3 35.6 5.25 19 14
Message Manger™ Chassis 17.8 48.3 38.1 7 19 15
File Server Chassis 17.8 48.3 38.1 7 19 15
Console Computer Chassis 17.8 48.3 38.1 7 19 15
Redundant Switches 4.5 48.3 35.6 1.75 19 14
Fan and Alarm Panels 4.5 48.3 35.6 1.75 19 14

The dimensions listed above for "Usable Vertical Rack Space" provide the actual vertical cabinet space available in the Large Floor Standing (CB3) Cabinet. Although this cabinet has additional space available, space at the bottom is required for the power supply and for air flow. Specifically, to properly cool the CB3 cabinet, 5.25 inches (13.3 cm) is reserved for air flow.

10.2) Power Requirements
Because Motorola customizes the configuration of each Unipage system to fit the needs of the service provider, the amount of current that the system draws will vary from system to system. However, the data provided on Figure 9 show common chassis configurations and the amount of current that is drawn. The data figures can be added together to provide a general calculation of total system power consumption.

All Unipage equipment that is rackmounted in the Unipage Large Floor Standing (CB3) Cabinet runs on -48VDC power. Although 110 VAC or 220 VAC power may be coming into the cabinet, the power supply converts the alternating current to direct current. Therefore, the figures provided are based on 48 VDC.

The CB3 Cabinet can be equipped with one or two 110 VAC/220 VAC Power Packs, depending on the amount of amperage required. For reference purposes, each 220 VAC Power Pack provided 3 Amps of power, and each 110 VAC provides 6 Amps. Two Power Packs therefore provide approximately 6 Amps for 220 V and 12 Amps for 110 V.

Motorola will soon have available a full range AC power supply that spans from below 110 VAC to above 240 VAC. It can handle both 50 Hz and 60 Hz and provides additional amperage for systems that require it.

All of the Console Computers pull approximately the same amount of current, so the power consumption of the CX9 can be applied to the smaller CX1R or the larger CX25. Peripheral VDT's that are connected to Console Computers are not included in the calculations. Figure 9
