Abstract

PURPOSE:To prevent the erroneous process without lowering the processing capacity of the main processor by securing the synchronization with every process block for the synchronous control between the main and secondary processors. CONSTITUTION:The control system comprises several units of secondary processor 5 which give the control to channel system device 6 including the exchange terminal and main processor 1 which controls these secondary processors. The control information for the exchange terminal is transmitted from processor 1 to processor 5 with every process block to give the announcement of the operation result every process block. Then the synchronous process becomes possible with every block between the main and secondary processors by confirming the result of every process block to be sent back. In such way, the synchronization is not required with every control information, and furthermore the integrated control can be given to the call station between processors 1 and 5 without lowering the processing capacity of processor 1, thus causing no erroneous process.
