We begin by presenting the fundamentals of the telephone network: how itbbegan, what the components are, and how they are connected. Next we review the basic nonelectronic telephone set. We then consider the effect of microelectronics on the construction and operation of the telephone set; for example, the effect on functions such as speech signal processing and interface with the telephone line, pulse and tone generation for dialing, and ringers. Next, we discuss how microcomputers use digital techniques and stored programs to enhance the performance and features of the telephone set. Digital transmission techniques, electronics in the central office, and network transmission concepts and fundamentals are explained. Finally, we consider new advances in cordless phone, mobile radio, and cellular phone technology. We also take a look at fiber optic technology and the Internet, as well as expand the coverage of wireless telephones-a very big market today. New information on high-definition television,modems, DSL lines, and cable modems has also been included.
