[mod.telecom] looking for reference book on modems/phones

narten@PURDUE.EDU.UUCP (01/28/87)

I would be most interested in finding a reference book describing
modems, sorts of technologies used, how they work, over what types of
lines/distances they are designed for, etc. I am also looking for a
good reference on phone line/equipment. For instance, what are the
types of leased lines, what are the technologies involved, how do they work,
what is line conditioning, how does it effect the types of modems you
can run over the line, etc.

I would like something fairly techinical at the level of John
McNamara's "Technical Aspects of Data Communication". His book is a
good start, but doesn't cover modems and phone lines in enough detail
(but then again, it is copyrighted 1977).

Does anyone have a recommendation?

Thanks,
Thomas

It sounds like you want the TELECOM archives. That's about
the best "book" on telephone equipment (amongst other things).

The Archives are kept on XX.LCS.MIT.EDU, in the XX:<TELECOM>
directory. They are:

	TELECOM.RECENT	Jan 1 1987 to present
	VOLUME-5.TXT	1986
	VOLUME-4.TXT	1985
	VOLUME-3.TXT	1984
	VOLUME-2.TXT	1983
	VOLUME-1.TXT	1982 and before.

The dates are approximate. I remember one volume spans 1.5 years
because I forgot to update the version number on the fiscal year
boundary and ended up filling it in at the end of the calendar year.

Someone else asked for the archives too. They are available
by anonymous FTP from XX (use any password).

Cheers,
