From the Back Cover

Telephony is a remarkable technology that has grown to be an indispensable part of our culture. The telephone lines represent an electronic interstate system that allows us (and our computers) to communicate in a variety of ways. Since deregulation of the industry in the late 70s, a whole new industry has blossomed, flooding the market with an assortment of novel devices and supplying us hobbyists with a fresh arena for ideas.

Telephone Projects for Electronics Experimenters will furnish you with the fundamentals and basic history of telephone technology and some hands-on projects for your enjoyment. Some of the projects include: 16-Channel DTMF Controller; Electronic Bell; Automatic Tape Controller Switch; Hands-Free Headset Telephone; Long-Distance Call Restrictor; 300-Baud Modem; and more. Best of all, we show you how to build your own Telephone Lab, giving you the tools to test telephone equipment and design your own special devices. If you have an interest in telephones and associated gear, this book is for you.
