Portable Telephones And Other Losing FCC Decisions Whats NPANXX - A Query About Dialing "1+" for Long Distance ---------------------------------------------------------------------- Date: 28 Jul 1982 2027-EDT From: Charles B. Weinstock <Weinstock at CMU-20C> Subject: Dart II Does anyone out there know anything about an alternative long distance service known as Dart II. They are advertising locally that for a $15 installation fee, and a $3 monthly charge, you can save 20% or more on interstate calls to anywhere in the country. Sounds like the Hart Line scheme to me, but I suppose it could be like MCI's new deal (call anywhere in the country, and MCI will take you on their net as close as possible, and then use Bell the rest of the way). Also, I wonder why the $15 fee?

(This is aired on some NPR [and other] FM stations, and on shortwave on WRNO, 2330 GMT Sundays, 11855 kHz. It is a "magazine" show about all aspects of radio, emphasizing shortwave and international broadcasting.) Glenn has been discussing reports from SWL's (shortwave listeners) about hearing these portable phones; they use the chunk of spectrum from 1600 to 1900 kHz, just above the AM BCB. The main reaction is disgust at yet another source of spectrum pollution degrading the RF environment. Also it seems many users don't realize that the signals carry farther than their home environs; they disclose private matters as if it was a closed-line telephone call. There are also opportunities for phone phreak abuse of these; using the portable portion to access someone else's base and thus make long-distance calls on their bill is one obvious technique. Another is to monitor the frequencies for users of Sprint, MCI, and the like, and decode the customer code numbers from the transmitted tones. I haven't been listening for those portable phone signals, but I gusee I should try -- any other SWL's out there picked up any? It's really amazing that the frequencies chosen for this service were so poorly determined; of course, the FCC has a long history of complete ineptitude in frequency choosing; consider the ill effects of the 26-27 MHz choice of CB frequencies, encouraging harmonic TVI and selecting frequencies which would skip for long-distance communications, and then trying to administratively prohibit what is technically possible! (Dumb!) Sigh, Will Martin ------------------------------ Date: 29 Jul 1982 11:20 EDT From: Axelrod.WBST at PARC-MAXC Subject: Re: Whats NPANXX - A Query About Dialing "1+" for Long Distance cc: Axelrod.wbst Several people have discussed the matter of dialing "1" + 10 digits in terms of distinguishing between 7 and 10 digit numbers. However, recently I have heard some discussions of another reason for having the Long Distance access code, related to the impending Bell split, and deregulation. The conjecture is that ATT Long Lines will no longer have a monopoly on long distance calling, and that other long distance comon carriers, (MCI, Sprint, etc) will ask for, and be granted access to local CO's. According to this conjecture, the subscriber might then have the option of dialing "1"+10 digits for ATT Long Lines, and say, "10"+10 digits for MCI, etc. (This would seem to introduce a whole new set of ambiguities, wouldn't it?) Does anyone have any information, or educated opinions on this subject? Art Axelrod Xerox Webster Research Center ------------------------------ End of TELECOM Digest ********************** -------
