<> At last a book I can recommend on the telephone system. It is UNDERSTANDING TELEPHONE ELECTRONICS by J. L. Fike, G. E. Friend, et al and from the Texas Instruments Learning Center. I got it for $3.49 from Radio Shack (Cat. No. 62-1388) and I'm not sure if it was on sale or not. It's 288 pages, about 5" x 7". Chapter titles: 1. The Telephone System 2. The Conventional Telephone Set. 3. Electronic Speech Circuits 4. Electronic Dialing and Ringing Circuits 5. A Microcomputer in the Telephone 6. Digital Transmission Techniques 7. Electronics in the Central Office 8. Network Transmission 9. Modems - Telephone Service for Computers 10.Wireless Telephones "Conventional telephone fundamentals, analog and digital electronic principles, newer digital techniques and hardware implementation are covered ..." It is well written, and while one of its purposes seems to be to tell people about TI's ICs in this area, it does cover most aspects of the telephone system. The emphasis is on the electronics, but you really don't have to know much about electronics to follow the discussion. It is much more on the conceptual level, and the system aspects, than on the details of wiring, etc. I.e., it won't give you step by step instructions on how to wire your house or fix your telephone set. I think it is a good book for someone who wants to find out more about the telephone side of digital data communications. --henry schaffer ncsu genetics
