re: several topics in Telecom 6:12;
PC Pursuit's inability to dial certain codes in 415 is not really
Pac Bell's fault either. They base their MU charges on distance.
Telenet simply chose a spot to put their (one) 415 access point.
If they were more concerned about local access rates, they could
plunk down a different access point, using a remote mux, FX, etc.
Private network managers plunk down FX lines that way all the time.
(Although with FGA rules being what they are, sometimes you don't
have to, but PC Pursuit doesn't seem to use FGA but 1MB instead.
Something about mixing line types in a network. Don't ask.)
re: Modular jacks for data. Digital's DECconnect wiring plan uses
modified modular jacks for RS-423 connections. They're just like
RJ45 except that the "key" is off center. We did this so that you
wouldn't plug the jack into the "other" hole. The DECconnect faceplate
has both a voice jack and a data (MMJ) jack. (You order the voice
jack to match your phone system.)
re: One-plus dialing. Let's get it straight. ALL exchanges are
SUPPOSED to eventually require 1+ dialing for all OUT OF AREA calls.
NOT toll calls, although most out of area calls are toll, and vice-versa,
unless you're in Brooklyn or someplace like that.
Historically, 1+ meant toll in some places, and still does, but that's
not what the Blue Book says. Hence 1+ is being phased _in_ to the
last holdouts, like DC Metro. This same "Blue Book" (whatever color
the new one will be, if it comes out, is beyond me; it's really
"Notes on the Network") reserved 950 and 976 for special services,
long before the services were created. Now that AT&T (who put it out)
no longer owns the numbering plan, all such matters (including area
code assignment, 1+ rules, the new Blue Book, etc.) belong to Bellcore.
They are the Administrator of the North American Numbering Plan. Per
order of the court.
Someday the blue book 1+ plan might actually be in use in most areas.
But I'm not holding my breath. The idea, btw, is to be uniform across
the country, so you don't have to know if you dial 1+ here for too
toll and 1+ there for out of area and just the number when in Passaic, etc.
