Application of Computer in Digital Exchange

Application of Computer in Digital Exchange Points : application of computer in digital exchange A computer is programmable electronic device that can store, retrieve, and process data. The use of computer and, more recently, microprocessor has brought a revolution in the design and operation of switching systems. In modern exchanges, particularly those using S.P.C., the use of a powerful and highly reliable computer control all the functions of an exchange.

All the information used in the translation processes are stored in the computer, thus it is easier to update the system when required. The computer has a complete overview of the system, so is able to analyse traffic patterns and diagnose faults more easily. Details of traffic and faults along with information for the preparation of user’s bills can also be recorded in the computer. Special services, which would be used by only a few users, can be provided more efficiently. The computer can also share between its own exchange and the remote exchange by a control signalling link. Thus functions which are expensive and inconvenient to perform locally can be controlled from a central computer:
