The service being tested in Orlando is being offered on an ordinary
#1ESS.  The reason for selecting Orlando is that, for the caller's
number to be displayed ALL the switches in Orlando from which calls
originate must be equipped with the appropriate software generic.
Orlando is one of the few cities in the country where there are NO
electromechanical switches still in servce -- everything is SPC.  
(Harrisburg, Pa is another such city which is why a similar test is
being conducted there).  

The service being tested also requires the equivalent of CCIS (common
channel signaling) between all of the local central offices to convey
information such as the caller's number from the origin office to the
final office.  The special equipment needed to receive caller's numbers
at the called number location essentially provides a CCS channel all the
way to the customer.  Lot's of interesting services will be possible
when CCS channels are widely available to customer locations, as
is planned for in ISDN standards.

Subject: Odd phone problem

I've been getting reports lately from people trying to call me that my
phone will often ring 1 to 6 times and then go busy. I've reported this
to GTE on the trouble number, they've supposedly checked things out and
found nothing. Any ideas on what this could be? Could it possibly be my
cheep phone?

Cheers,

Re:   2400 baud modems
Date: 5 Dec 84 23:27:16 GMT

For those of you in the market to buy 2400 baud modems I want to
inform you of a great deal.  I would like to state that I am not
affiliated with ANY of these companies, and I am not receiving and
benefits by posting this information!

After spending a few days pricing modems I have compiled the following
information (saving the best for last).  If anyone has any additional
information I would greatly appreciate it.

We were interested in rack mounting them so most of the prices given
are for cards that would plug into a rack.  "box" refers to a stand
alone modem.

These people had by far the best deal.
The list price for the Stand Alone (box) modem is  $ 795
The list price for the (rack) mounted modem is ~$ 700.

Besides starting off $ 200 less than everyone else their
quantity discounts are very good.  The Stand Alone modem
will be available starting January, and their rack mount
modem should be available February.

Here is a Quantity discount price list.

Quantity	%dicount	S.A.	rack
========	========	====	====
    1		   list		$795	$700
  2-5		   10 %		 716	 630
  6-10		   20 %		 636	 560
 11-25		   25 %		 596	 525
 25-		   30 %		 556	 490

For all of you usenet sites that are still running 1200
(or possibly even 300) the modems will pay for themselves
very quickly.

From all of the literature that I have recieved here are
a few of the advantages of this modem above the others:

1) works at 300 or 1200 or 2400 asyn	(others only 1200/2400)
		   1200 or 2400 sync

2) Stores 10 numbers (40 chars each)	(others only 1)

3) For tone dialing it dials ALL 12	(others only can generate 
   tones including (* and #)		 numbers 0-9)

   This last one caused a nasty problem when we needed to
   generate the extra tones because some of the sites we talk to
   have switching systems that require them (Gandalf).

4) Will automatically change the speed   (some of the others needed
   to the other modem.			 a manual intervention).

     Could someone explain how these phone surveys done by computers work??
I just got a call from one,  and it wouldn't hang up if I put the phone on
hook for a while,  so I gave it (her?) a carrier tone and it tried to connect
to my modem and then hung up.

	In the wonderful new world of equal access, where you can select
your long-distance carrier differently for every call, there are assigned
codes for a whole bunch of new long-distance carriers about which I basically
know nothing at all.  Some require that you sign up with them before you
use them; some say you can use them at will and your calls will appear on
your next bill.

	Can anyone tell me where I can get a list of all valid equal-access
codes and the carriers they represent, together with an indication of which
require prior sign-up and which you can just go use?

Subject: Q: telephone problem due to programming
To: telecom@UTEXAS-20.ARPA

after my phone stayed strangly silent on the 25th and 26th, I decided to call
my 'listed' number from my second line, and sure enough, I got a fast, busy
tone, which I have often heard when the lines in a certain area are overloaded.
Strangely enough, other phones in the area, including my second line, did not
show similar symptoms.  Also the phone worked perfectly for dialing out.
So, after the problem did not go away I reported it on the 27th, and was told
that I should not expect anyone to check it out until the 31st or later.
On the 28th, I decided that I was less than satisfied with that response time,
which basically meant that noone would be able to reach me either for X-mas
or New Year's as noone knows my second number.  So I decided to inquire if it
would be possible to put a recording on my first line, informing of my 'new'
number, or to enable call-forwarding for the duration of the problem.

Not surprisingly, really, I got the run-around, noone seemed to understand
what or how to achieve the effects I desired, Repairs and the Business Office
of Southwestern Bell gave me 'circular references' to talk to the other.
Calls to me were not made or returned, as was promised, until, late Friday,
a 'new voice' called, informing that it was all a computer error, which had
caused the problem on several lines.  When asked for more info on the problem,
the person could not give more, as 'that was all she was told'.

I intend to try to dig around some more and find someone to talk to who can
give straight answers, but in the meantime, if anyone out there could add
some factual knowledge to what might be going on here, or how one might
penetrate the front-people of SouthWestern Bell and which department or
job-title to ask for to get answers, mail me.  One other "strange" matter:
lately, I had noticed a strange ticking sound on that line, as well as a
wooshing-sound, kind of like a tape-recorder, which has since disappeared.
Could it be that I had been bugged ???
