I've got a microprocessor system design that I need to interface with phone systems (old styles and new). I'm desperately looking for a good book on the subject. One that does talk in terms of real life stuff (not how it could work or should work) with real "expected" voltage/impedence/etc. values. I don't need to know about what goes on at AT&T headquarters, just how to interface to the handset and/or phone jack. Is there such a book out there? What do modem designers use? I've got a RatShack book and it's worthless to use for real applications info. Thanks in advance, jons

For (further?) info on telephone theory, see Radio Shack catalog #62-1338 entitled "Understanding Telephone Electronics". It is 256 pages long (or 2^8) pages long, and costs $3.49, not including tax (which is about 1.36 cents per page - a bargain). Seriously, it's a decent book, especially if you want to build a telephone. I used it to help a friend build a phone patch for his ham radio. /Chris
