Last year the TV show, 60 minutes, did a feature on phone fraud in the
US.  They estimated it was costing US phone customers, especially
businesses with PBxs, billions of dollars because of fraudulent use by
hackers.  More recently, CBC Radio in Canada did a news story on phone
fraud in which they said a Ministry of the Ontario government had been
hacked for $50,000 in one month.

Is this becoming a major problem for business everywhere? 

I'd be interested to hear of incidents as I may know of a solution.

A while ago someone on this group posted a number for Cellular Direct
and/or some other mail order source for cellular phones and 
accessories. 
Does anyone still have those numbers handy?

I haven't seen anything on comp.dcom.telecom about this before so I
will explain what I know ... 10XXX codes are being changed to 1010XXX
(e.g. AT&T @ 10288 is now 1010288) and new carriers are being assigned
to 1015XXX to 1016XXX.  I don't know how the rest of it is going to be
assigned, but this change is quite interesting.  It was planned
sometime in 1993 and I don't know when it was actually implemnted, but
it already works if you dial 1010XXX around Michigan (at least with
Ameritech, I don't know if some of the smaller 'alternative' carriers
in mid-michigan have adapted to this yet).  I imagine that 10XXX
dialing will be discontinued sometime in the future (or at least there
will never be any 101XX codes)  If anyone else has information on
this subject, please post it!


Peace,

Chris

What kind of noise/distortion does American-style bit-robbing cause to
voice band signals transmitted through PCM channels?

(The reason I ask is that I wonder how much bit-robbing affects V.34
modems.)

I have a requirement which calls for encrypting the data which crosses
our T-1.  I would prefer this to occur "transparently" with respect to
existing equipment installed.

Has anyone heard of a product which can do this?


Thanks in advance,

Subject: Where Does ISDN Fit In?


When talking about telecommunications in computer-networking, people
often talk about t-1,2,3 or other type of line that specifically
define the bandwith of the connection.

What about ISDN, how do you fit that in these terms?  What is the
standard bandwith of ISDN, and how is it when you only use it for
computer-data transfer when we speak about t-1s.  Is it like an 15kHz
analoge line, that is used for Radio Signal transfer.

In short when do I use ISDN, over other alternatives?


Thanks.

I would appreciate very much if someone can recommend a good book or
some other material which has sufficient information on the 
architecture 
and protocols of the US digital standard IS 54.

Is it possible to buy a copy of the standard itself? (I mean not the
whole thousands of pages but a summary.) Or is it strictly 
proprietary?
