Integrated Circuits Spur Digital Telecommunication

The breakthrough of fully digital, computer controlled telephone switching technology and its consequent evolution towards fully digital, end to end communication in an integrated services digital network which unites a wide variety of voice and non voice services, has only come about with recent advances in microelectronics. After a brief introduction on system structure, this paper will summarize the function, status, and application of the most important ICs which will have a major impact on digital voice-/ data communication.
