ABSTRACT:
The objective of this research is to design and implement a multi-processors control system to control a telephone exchange. Ten processors used to design the multi-processors control part. Each processors will control 100 subscribers forming a small telephone exchange (node), the ten processors will manage the operation of 1000 subscribers in total. Each telephone exchange control unit will work as multi-processes and the whole system will work as multiprocessors telephone exchange. A small model for the proposed system has been implemented, the model consists from two nodes (small telephone exchanges), each node has two subscribers and space division switch unit has been used with 25 calls can carried on at once. The control unit was implemented using ATMEL 89C51 microcontroller with several 74xxx IC series. The message passing technique used to communicate between the nodes with special protocol. Finally the implemented model has been tested and worked successfully.
