Abstract

PURPOSE:To enable the best constitution of a system according to a request from a switchboard while making it possible to use invariably the same control system regardless of the circuit capacity of the switchboard, by connecting general processors to a channel network. CONSTITUTION:This system is equipped with signal control processor 2 corresponding to a group of equipments connected to channel network 1, connection control processor 3 which exercises connection control over network 1 and is provided corresponding to traffic intensity, bus 13 for information transfer between processors 2 and 3, memory 7 stored with busy information of a trunk, and trunk selecting circuit 5. Then, a trunk selection control command is sent out from processor 3 to processor 2, which exercises the trunk selection control and sends information on the control result to processor 3. As a result, invariably the same control system can be realized.
