Are codes like 10222 and 10288 supposed to work from residence and > business phones as well as pay ones? Absolutely. We just got equal access on our business lines here and they were switched to MCI; I reprogrammed my auto-dialer to use 10288 before all my calling card calls. If you're placing calling card calls from a business or residence where you don't know the carrier, always give the 10288 (or whichever) a try. > 2. I just passed through the Lynchburg, Va. area, and used a pay phone > (ostensibly C&P) to place a 0+ call inter-LATA, and it went via ITI. This reminds me of something I saw a few weeks ago in Waldorf, MD (southern Maryland - C&P territory). On the front of a 7-11 store along U.S. 301N was the requisite row of payphones (4). Above the payphones was a large white banner with blue letters proclaiming C & P Public Phones Are Back! I guess they had COCOTs and got complaints..... > From: Sowa > Subject: Re: Implementation of 911 Enhanced Service through PBX > This is an interesting operation.

I understood the original posting to mean that the campus had DID trunks to extensions on-campus, but that without outgoing ANI, all the 911 service would be able to tell was that the 911 call originated on one of the university's outgoing trunks. With ANI from the campus, a regular directory number would be provided with no separate extension, much as (as you mentioned) some PBXs do for billing origination purposes. > An Enhanced 911 PSAP has an address database that must be maintained > by someone, how or will the university keep the database informed of > extension moves. I imagine this will be one of those things that's going to be more work than anyone planned.... > TELECOM Digest Mon, 15 May 89 02:00:00 CDT Volume 9 : Issue 164 > From: julian macassey > Subject: Re: Jack specifications > [Description of in-series alarm wiring.] Usually, you put the > alarm on the least used pair, often the last or your FAX line. I'd suggest not putting it on a FAX or modem line. For quite a few months here we were having problems with both our FAX and modem connections being terminated randomly. For modem use, it was obvious that no connection ever lasted for more than an hour. It turned out that all the lines involved were passed through alarm systems (at least one for intrusion and one for fire) and the systems were "testing the lines" hourly! We decided to get dedicated lines for them, since, in addition to this annoyance, we didn't want an incoming call to potentially hold up the alarm. (They weren't ground-start lines.) -- John Owens john@jetson.UPMA.MD.US uunet!jetson!john +1 301 249 6000 john%jetson.uucp@uunet.uu.net
