Subject: Zetron DAPT-1000
Date: April 23, 2006 10:25:52 AM CDT

I'm curious,
I recently bought a Zetron DAPT-1000 paging terminal off eBay. It has the POCSAG roms in it, along with two tone. I bought it, for an encoder, for my ham radio severe weather alert paging system I am setting up. Trouble is, that I know it can be programmed by DTMF tones, but Zetron no longer supports it, and they will not give me any information on it. Do you know anything about the programming of it?

Broadband over Power Lines (BPL)

California Public Utilities Commission Approves BPL Regulations

NEWINGTON, CT, Apr 28, 2006--Saying that broadband over power line (BPL) will bring Internet access to "underserved communities," the California Public Utilities Commission (CPUC) has adopted regulatory guidelines for electric utilities and companies that wish to develop BPL projects in that state. While the Commission's BPL guidelines include a requirement to maintain the safety and reliability of the electric distribution system, the state agency has no jurisdiction over radio frequency interference, which received no mention in the PUC's news release. ARRL Laboratory Manager Ed Hare, W1RFI, points out that the utility industry still must meet another tier of federal regulations that govern permitted BPL signal levels and interference issues.

"Although this action addresses how BPL operators will be responsible to state regulators, it does not address any of the technical problems with BPL in any way," Hare observed. "Utilities will still have to carefully choose BPL vendors with a proven track record of preventing interference complaints."

Benefits vs Uphill Battle

The CPUC said it wants to foster BPL deployment to solve the "last mile" problem of broadband delivery and to increase consumer choice in broadband providers. "BPL has the potential to bring broadband Internet services to communities who do not have broadband service available today from the telephone companies or cable companies," said CPUC President Michael R. Peevey. "BPL can also provide benefits to electric customers by enabling valuable 'smart grid' applications that could improve electric system reliability and support money-saving energy management technologies."

One commissioner suggested that BPL faces an uphill battle. "This is a nascent technology with technological, market, and financial hurdles before it," commented CPUC member John Bohn. "By removing unnecessary regulations from its path, we free BPL entrepreneurs to invest and take the risks they want, while protecting ratepayers from any downside."

Demonstrably Wrong

ARRL CEO David Sumner, K1ZZ, said that while the League's concern is with BPL interference and not with the viability of BPL in the broadband marketplace, "it's odd to see the California PUC echoing the pro-BPL rhetoric that was coming out of the FCC two years ago and that is so demonstrably wrong today." Sumner points out that BPL has been around for years now, and "after all the hype," the most-recent FCC statistics show no more than about 4000 BPL lines in service in the entire US.

"The California PUC would better serve its citizens by focusing on more capable broadband technologies, such as fiber and wireless, that do not have the potential to disrupt radio communication," Sumner concluded.

Utility Commissioners' Task Force Expresses Reservations

The February 2006 National Association of Regulatory Utility Commissioners (NARUC) "Report of the Broadband over Power Lines Task Force" included reservations about the technology expressed by utilities themselves. "First Energy commented that it is still not clear that BPL technologies live up to their hype," the report noted. Con Edison said the technology still has credibility issues. "Don't tell me what it can do; show me what it can do," the report quotes the utility. PPL and Idacomm called a halt to their BPL activities in Pennsylvania, Nevada and Idaho. NARUC's year-earlier task force report pointed to the unclear regulatory climate for BPL and the costs of its deployment in rural areas as obstacles.

ARRL Staffer Testified on Early Policy Draft

In February 2005, ARRL staff member Dean Straw, N6BV, testified at a CPUC public hearing on an earlier CPUC draft on broadband deployment—including BPL. In his testimony, Straw—an electrical engineer and an ARRL technical editor—decried the fact that a section of the draft policy document dealing with BPL neglected to mention the technology's disadvantages.

He cited interference from BPL to radio receivers, interference to BPL from radio transmitters and a lack of bandwidth for expansion, especially in instances where BPL interference must be mitigated in some fashion.

"We are not opposed to Internet broadband services," Straw maintained on behalf of the Amateur Radio community at large. "We're not categorically opposed to Access BPL, but we are opposed categorically to interference." Straw urged caution against what he called "a wholesale embracing" of BPL on the part of the CPUC.

The policy the CPUC adopted April 27 stemmed from a draft developed by CPUC member Rachelle Chong, a former FCC commissioner.

CPUC's Goals

The CPUC said its action, among other things, would allow the flexibility of third parties or electric utility affiliates to invest in and operate BPL systems; require utilities to follow affiliate transaction rules for transactions between a utility and BPL affiliate to protect against cross subsidies and other anti-competitive concerns; require companies installing BPL equipment on utility infrastructure to pay pole attachment fees; align investor risks and rewards, including ratepayer/shareholder sharing of any access fees exceeding the pole attachment fees; and exempt certain types of BPL-related transactions from regulatory review.

House Committee Okays Telecoms Bill with BPL-Interference Study Amendment

NEWINGTON, CT, Apr 27, 2006—The US House Energy and Commerce Committee's version of the Communications Opportunity, Promotion and Enhancement (COPE) Act of 2006 includes an amendment requiring the FCC to study the interference potential of BPL systems. After spending two days marking up the measure, the panel voted April 26 to send the much-talked-about "telecoms rewrite" bill to the full House for its consideration. "Outstanding news!" was the reaction of ARRL CEO David Sumner, K1ZZ.

US Rep Mike Ross, WD5DVR, (D-AR)

"This is a major victory for the ARRL," he exulted, noting that the amendment "received significant opposition" from utility companies. Rep Mike Ross, WD5DVR (D-AR), proposed the amendment, and, with the support of Committee Chairman Joe Barton (R-TX), the committee agreed by voice vote to include it in the bill.

A year ago, Ross sponsored House Resolution 230 (H Res 230), which calls on the FCC to "reconsider and revise rules governing broadband over power line systems based on a comprehensive evaluation of the interference potential of those systems to public safety services and other licensed radio services." The non-binding resolution has six cosponsors.

"Hundreds of ARRL members who wrote their congressional representatives in support of Rep Ross's H Res 230 helped to achieve this week's success with the COPE Act amendment," Sumner observed.

A more-widely reported Internet "network neutrality" amendment to the COPE Act bill was defeated. The measure will get a number next week.

A statement released by Ross's office notes that his amendment, which received unanimous committee support, "would guarantee that valuable public safety communications and Amateur Radio operators are not subject to interference." One of two radio amateurs in the US House, Ross said infrastructure-free Amateur Radio, "often overlooked in favor of flashier means of communication," can maintain communication in disasters that bring more modern technology to its knees. Ham radio operators "are often the only means of communication attainable in a devastated area," Ross said.

"I believe it is imperative that the interference potential [of BPL] is thoroughly examined and comprehensively evaluated to ensure that deployment of BPL, which I do support, does not cause radio interference for Amateur Radio operators and first responders who serve our communities," Ross added.

The COPE Act BPL amendment adds a section (under Title V) to the proposed legislation that would require the FCC to study and report on the interference potential of BPL systems within 90 days of the bill's enactment. The Commission would have to submit its report to the House Committee on Energy and Commerce and the Senate Committee on Commerce, Science and Transportation.

"This puts the House Energy and Commerce Committee on record as having concerns about BPL interference," Sumner said. "If we are vigilant in protecting it against deletion on the House floor—assuming the bill is approved by the House—the BPL language will be included in the legislation that goes on to the Senate."
