------------------------------ From: ai093@freenet.carleton.ca (Paul Murray) Subject: Phone Fraud - PBXs Reply-To: ai093@freenet.carleton.ca (Paul Murray) Organization: The National Capital FreeNet Date: Tue, 3 Jan 1995 23:01:46 GMT 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. Paul J. Murray [TELECOM Digest Editor's Note: It is a very major problem. Let's hear your solution.

Date: 3 Jan 1995 19:24:36 -0500 Organization: Public Access in Ft. Lauderdale - SatelNET (305) 587- 1930 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!

Date: Tue, 3 Jan 1995 00:14:43 MET 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.)

Organization: The Signature Group Date: Tue, 3 Jan 1995 02:47:45 GMT 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, Quinn Lanus qlanus@sigg.com ------------------------------ Date: Tue, 3 Jan 1995 02:11:06 EST From: Daniel Ritsma 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. ------------------------------ From: Dharshana P. Jayasuriya Subject: Need Information on IS-54 Date: 3 Jan 1995 15:44:52 GMT Organization: University of Trondheim, Norway 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?
