An overview of the ways in which the microprocessor is impacting the design of telecommunication systems is presented. The concept of the microprocessor as a software customized, catalog device is discussed. The various processor structures which are being employed in telecommunication systems utilizing microprocessors are emphasized and several examples are described.

Microprocessors in telecommunication systems

The modem as we know it today is a product of research done for the Defense Department by MIT Lincoln Laboratory and Bell Telephone Laboratories in the 1950’s. Encouraged by advances in data processing technology, scientists at these research centers concentrated on finding ways to improve the speed and the accuracy of data transmission using  existing  facilities of the  nation’s  vast elephone network. A great deal of study went into understanding telephone line parameters and deriving techniques  that  could  work  efficiently parameters.
