[TELECOM Digest Editor's Note: Our site, nwu.edu was victimized by a
hacker last Thursday. Somehow he got in as root and did quite a bit of
damage. The entire site was down for a couple days while repairs were
made. At that point, by the weekend, the computers were operational
again, however our links to the outside world (that is, our dial ups
and our telnet, rlogin, ftp, etc) remained shut down until some 
additional
changes were made. Our links to the network and our dialups were 
turned
back on late Monday night. The sysadmin here has complete details on 
it
but I discourage writing or bothering him as there are still some 
repairs
going on and he is quite busy. I am grateful he and his staff made the
enormous effort they did in order that things like this Digest could 
get
back in publication as quickly as possible. I think we now have Caller-
ID
on our dialup lines. Its too bad hackers have to ruin things for 
everyone
else.  PAT]

Subject: When Will PBXs Go Away?
Date: 31 Jan 1995 10:17:45 -0500
Organization: Georgia Institute of Technology


What is the current thinking on when a PC (powerPC, whatever) replace
the PBX? i.e. when can I run my T1 from the telco with my voice trunks
on it into one card on a PC and have it route voice over the LAN to
other desktop computers that double as phones? It will probably be a
time curve: first available for small offices (ten users) on an 
ethernet, 
then a while later available for 200 lines on a faster LAN, etc. What
says the net? My Mitel sx200 lite has a 68000 for a processor: it's a
MacPlus! Surely the cpu horsepower is available to replace lots of
dedicated TTL and switching hardware. I was just at a briefing from
Apple and they're working with the PBX makers for a Geoport Mac to be
a voice terminal behind a "big maker" PBX. But who are the startups
that are out to kill the PBX makers?

Organization: Medical Laboratory Network; Ventura, CA


We had a discussion about the Sprint offer of one cent per minute for
customers in California using them to carry their intraLATA calls.

One of the caveats mentioned here was that customers on any of their
'saving' plans (say, The Most) would not be eligible for the special
rate.

I am with The Most plan, and today I got my bill. There are several
intraLATA calls, all billed at one cent per minute. This confirms what
I was told on the phone by Sprint customer service: the rate is good
for all of the residential customers (the person didn't specify any
geographical restrictions, i.e., Northern versus Southern. I'm in
SoCal [Ventura, to be precise]).

Recently there has been a lot of talk about having to do ten digit

number.

I have a number of users who are going to be affected by the above and
am looking for a good explanation for them.  I'm myself am not
completely sure myself of all the reasons for making the changes to
out-of-area dialing and would like to get it right the first time :-)

Could someone e-mail me with an explanation?


Thanks!

[TELECOM Digest Editor's Note: Actually, it is eleven digit dialing, 
not
ten digit if you count the '1' on the front. However, one would think 
that
when this becomes universal all over the USA that we could in fact get 
by
with ten digits since the '1' would no longer be needed; there would 
be
no 'local' calls to distinquish from 'long distance'. Since everything 
that
we dial would consist of area code plus seven digits, there would be 
no
need for a '1' to indicate that 'what follows is an area code' -- 
everything
that follows would be area codes!  It would be nice to see the '1' 
vanish
under those cirucmstances. Or maybe they will insist on keeping it 
using
as their rationale that '1' is also -- by coincidence -- the country 
code
for the USA and Canada, and that what we are really dialing is country 
code,
area code and seven digit number. As to *why* they are imposing it on 
calls
within the same area -- as is supposed to be the case in Chicago 
beginning
sometime in 1996 -- I do not know. Various reasons have been given.

How do I get one? Other than ATT/MCI/Sprint, are there other people
who can provide an 800 number cheaply?

How do I minimize my cost?

How do I get 800-CALL-MY-BUSINESS? Do I have have to pay extra for a

[from Bell News, 23 Jan 95 - content is Bell Canada's]

[from photo caption...]

I've got one ... The event began at 9 a.m. and by 9:04 a.m., it was
over. On December 15, a new NXX (555) was opened for 1-800 numbers
across North America allowing for approximately 8,000 new numbers. We
were competing against all the other telephone companies in North
America to get as many of them as we could. Doris Tesolin, an 800
Service Centre associate, celebrates getting the first number just
after the 9 a.m. start. At exactly 9:04 a.m., the entire 8,000 numbers
were gone and the 800 Service Centre was successful in securing about
40 numbers for our customers.

[dl note: apart from 555.1212 and perhaps 555.4141, and with a 
capacity of
10 000 possible 800 555.xxxx numbers, what happened to most of the 
other
2000 numbers available in 800-555?]

[from Bell News, 9 Jan 95, content is Bell Canada's]

Our LD assistance comes in 17 languages.

Our customers can now receive assistance in making long distance calls
in the language of their choice.

In a six-month trial which began last December, our operators are
offering 24-hour access to Language Assistance, at no extra charge,
to assist customers in completing their long distance calls.

This month and next, customers will receive information on dialing "0"
for language assistance via a SIM (Short Informational Message) on
their monthly bill.

"It's another example of how we continue to find new services to
delight our customers," says Janet Garrod, of Consumer Market
Management.

The trial will measure customer response and demand for the free
service, assess the cost and benefits of providing such a service, and
identify the most frequently used languages.

                         -------------

Our ethnic customers can receive assistance in the following 17 
languages:

Mandarin; Cantonese; Japanese; Vietnamese; Korean; Hebrew; German; 
Spanish; 
Polish; Russian; Portuguese; Romanian; Tagalog; Italian; Hindi; 
Arabic; and 
French.

Subject: RBOC Aids Motorola's ISDN Push


In the 1/23/95 issue of {PC Week}, page 55, there is an article that
describes a joint effort between Motorola and Ameritech to bundle ISDN
hardware and services for home and office use.  ISDN BRI starts at
$28/mo and the RBOC will sell Motorla's terminal adapter for $399 or
$19/mo for two years.

Ameritech also provides it's own software for the ISDN and has a
similar program using two T-1's.  This is not an ad, I work for
neither, just want ISDN at home at a price I can afford and expect
others do too.

Subject: Plumber Arrested: Fraudulent Call Forwarding
Organization: Westmark, Inc.
Date: Tue, 31 Jan 1995 01:43:14 GMT


A story in the Monday {New York Times} describes a Philadelphia area
plumber who subscribed to Call Forwarding Ultra.  This is a service
offered by Bell Atlantic which allows subscribers to control
call-forwarding from a telephone other than the one being forwarded.
This plumber allegedly subscribed to the service for several of his
competitors without their permission, and then forwarded their calls
to his telephone.  He then intercepted some or all of their business.
He was found out after approximately one month, when one of his
victims was complimented by a customer for a job well-done -- a job
the victim never did!

The perpetrator is currently in jail pending trial for an un-related
charge of battery, but is now being charged with numerous counts of
wire fraud, theft of business, operating a business under a false
identity, and similar charges.

[TELECOM Digest Editor's Note: This same report appeared in 
alt.dcom.telecom
today submitted to that newsgroup by Jack Decker who concluded by 
saying 
this was a good reason telcos should password accounts, presumably to 
prevent
fraudulent Call Forwarding among other things. The thing he neglected 
to
mention -- nor was it mentioned by Dave Levenson here -- was that Call
Forwarding Ultra (or Enhanced Call Forwarding or Remote Call 
Forwarding as
it is known in other telcos) *does* require a password. If you have 
Call
Forwarding on your line otherwise -- you have to already have it 
installed --
then if you further subscribe to 'Ultra' you are given a personal 
password
or PIN. You dial a seven digit number which is the switch itself, 
begin
by identifying yourself with your PIN, then give the number you wish 
to
have (un)forwarded, followed by the number (if turning it on). The 
change
takes effect immediatly. Needless to say, the switch keeps its own 
records
on who called it from what remote location, with none of this 'private
entry' stuff permitted. Typically, that number at the switch will not 
even
answer or respond if the switch cannot tell what number is being used 
to
call it before it answers. Also, no other custom calling features can 
be
changed in any way, nor can any of the many other features of the 
switch
be programmed using that PIN.  So telco does make reasonable 
precautions
to insure that one person cannot just call up and change the 
forwarding
for someone else.  

What goes around comes around:  Does anyone remember the old anecdote 
about
the original development of automatic switching involving Alvin 
Stroger?
Mr. Stroger was an undertaker a hundred years ago; he believed that 
the
operators on the manual exchange serving his community had been bribed 
to
divert calls from the public seeking funeral/burial services to his 
compe-
tition. So the story goes, he developed the switch which came to bear 
his
name as a way to be certain that manual operators at telephone 
exchanges
could not wilfully give away his business to his competitors.   PAT]
