TELECOM AM Digest Friday, 9 July 1982 Volume 2 : Issue 84 Today's Topics: Cellular Radio - Gold Rush At The FCC Installation Wiring - Do It Yourself Problems With OZ Dialups - Two Possible Ideas ---------------------------------------------------------------------- Date: 7 Jul 1982 1856-PDT Sender: GEOFF at SRI-CSL Subject: Gold Rush At The Fcc. From: the tty of Geoffrey S. Goodfellow Reply-To: Geoff at SRI-CSL Is the title of an interesting article on the 'Unprecedented Returns' and licensing aspects of cellular radio in the july 12th edition of fortune on pages 102-112. ------------------------------ Date: 8 Jul 82 00:36:55 EDT (Thu) From: Steve Bellovin <smb.unc@UDel-Relay> Subject: Installing your own wiring Here are some items from a N.Y. Bell billing insert I thought would be of interest to readers of this list. In N.Y. customers are allowed to install their own wiring. The monthly charge for wiring is separated into an "investment charge" ($1.04/mo. for residential lines; $.72/mo. for businesses -- a curious reversal) and a "maintenance charge" ($.75/mo. for each residence phone; $3.51/mo. for each business phone). Customers can avoid both charges if they supply all of their own wiring; also, they are not liable for the investment charge if their wiring was installed after April 3, 1982. If you want to install your own wiring, N.Y. Bell offers three options: a "Standard Network Interface" at $11.25 (plus a premises visit charge), a "Network Interface" at $4.25, and a "Demarcation Point Arrangement". The first two are modular jacks installed where the phone line enters the building ("The SNI is more expensive because it is equipped to make testing of your line easier for you and the company if a trouble condition should develop. But, it's your choice...." [sic]. Anyone know what the difference is, or how repairs are billed in such situations?); the DPA is just an officially-blessed modular jack that you can plug your own wires into. They will supply a free kit to convert non-modular jacks to modular ones, thus making them eligible to be declared DPAs. A new booklet, "Providing Your Own Telephone Wiring" is available through PhoneCenters or the local business office; it sets out the regulations for rolling your own. One other item in the same insert: they no longer charge for Touch-Tone lines (line charge only; equipment not included) for folks who use the feature only to "access computers services and/or specialized long distance common carriers", and who do not use it to make local calls. If you're in such a situation, they want you to call them. ------------------------------ Date: 8 July 1982 06:03-EDT From: James M. Turner <JMTURN at MIT-AI> Regarding the OZ dialups: The problem you were having is that the OZ tips were on MIT-restricted lines. This is a problem that the clone company propagated on MIT by making assumptions. And yes, when this occured, I called the MIT operator (253-1000), and told her I needed an inside mit data phone dialed for me, and could she plese dial mumble. As far as I know, this problem went away after Ma Bell had the facts explain at her. James ------------------------------ Date: 8 Jul 1982 1442-EDT From: John R. Covert <RSX-DEV at DEC-MARLBORO> cc: rkb at MIT-AI Subject: Intercept anomaly It is VERY unlikely that the problem you are having has anything to do with which line you are calling from. Much more likely is that at the time you were calling from your regular line, the number you dialed was available, but when calling from your other line, it was busy. But why didn't I get a busy signal, you say? Well, it's not uncommon for lines in hunting groups to hunt to numbers which have been removed (i.e. the size of the hunt group has been reduced or the hunt number was improperly entered). But why did it tell me that the number I dialed was out of service, rather than the number that was hunted to? Because No. 1 ESS sends the number dialed, not the final number, to AIS. (I once forwarded my phone to a friend's phone in the same C.O. the day his phone was to be removed. Calling my number dropped you into AIS with the recording refernecing my number.) Why did the AIS database point the number to the MIT main number, even though that number was actually in service? One of two reasons could be responsible for this: The AIS database often, in order to save memory, points to the same recording for large groups. Also, the AIS database is not always changed immediately when a new number is connected (in fact, it very seldom is). [That seems inconsistent with the above statement by JMTURN, which states that the OZ dialups had been restricted MIT numbers. Can Rkb's main number can call restricted phones at MIT? 617-497 and 617-258 are on the same ESS machine, I believe. --JSol] ------------------------------ End of TELECOM Digest ********************** -------
