This is a great cross-over book that still covers the rotary dial phones as well as the more up to date keypad phones. The fundamentals of basic analog and digital electronic principles are covered in ten chapters:

1) The Telephone System
2) The Conventional Telephone Set
3) Electronic Speech Circuits
4) Electronic Dialing and Ringing Circuits
5) A Microcomputer in tbe Tekephone
6) Digital Teansmission Techniques
7) Electronics oin the Central Office
8) Network Teansmission
9) Modems - Telephone Services for Computers
10) Wireless Telephones

The book is full of circuit diagrams, illustrations and the odd photo or two.
At the end of every chapter there is a quick quiz, which helps you check that you have understood what you have just read. You don't have to do it, but it is there just in case.
