[comp.dcom.telecom] Caller ID Questions

cayz@udel.edu (James Cayz) (04/09/90)

	Here in the land of 302 / Bell Atlantic / Diamond State Bell,
we are expected to get Caller ID on May 1 (pending FCC approval).
Before I run out and get it, I have a few general questions.  Please
reply to me directly - I can re-post to net or directly to others who
request a summary.

	1) The cost for the service is $5 for installation + $6.50 /
month, the $5 being the turn-on cost for any CLASS feature.  Isn't
this a little high, monthly (maybe I missed this, but I thought I had
seen some of you say it was free after activation charges)??? This is
not the charge for Privacy (which, although they don't have yet, they
are definately thinking of making available).

	2)  Caller ID Units - I have called the Bell Atlantic Consumers
Services group, and the only unit w/out a phone that they have in current
supply is their most expensive model, that holds 35 last numbers, read vs. new
numbers, etc, etc, and is $79...  Their other 2 models are so "sold out" and
so back-ordered that they don't even know when they will (if ever) have them
again.   Should I check elsewhere for these units, and how much do they cost
(where / general range / features ) ????

	3) Will we (ie, in the next 30 years) see Caller-ID
cross-country?  Not every number, but maybe all numbers on digital
CO's??

	4) Most important question, and most convoluted...  I want to
get Caller ID for home (302-737-XXXX).  No Problem.  However, I have
friends who live at the University of Delaware, as well as people I
would rather not talk to, but have the answering machine kick in :-) .
Now the university is on this mess of a system, with dorms (ie,
friends) on 302-738-XXXX and offices (ie, other people) on
302-451-XXXX, but they are cross-connected (so dialing '5' + XXXX gets
an office from a dorm and vice-versa).  

I had heard that Caller ID sometimes displays the outgoing trunk line
# from a PBX, and wondered what I would get on my Caller ID box.  The
rep could not find out, definitively.  Now, since they are such a messy
system, would they share outbound lines?  Would I maybe get "451-0000"
for both a "738" and "451" call, or would I get "738-0000" for a "738"
call, "451-0000" for a "451" call?  Rep still didn't know.  But, she
did have a great piece of info - Call Block works fine this way - If I
Call Block'ed 451-1234, 451-1233 and 451-1235, as well as all other
451- & 738- numbers would still get through.  (ie, the Call Block part
of CLASS _can_ distinguish between separate extensions of a PBX).  The
Question Is - What does Caller ID do (both "supposed to" and "does
here in my area") with PBX and multi-exchange PBX calls (assuming the
Caller ID is connected to a number outside the PBX's).

	Thanx again for any replies -_please_send_them_directly_to_me,
I will summarize to net if I get > 10 requests (or 1 from the
moderator :-) ), otherwise I _will_ send each requestor a summary via
direct e-mail.
