Abstract

PURPOSE:To shorten the time of channel driving processing by direct driving a channel by a switching connection control processor in a time-division telephone exchange system of a functional load decentralized type on a multiprocessor system. CONSTITUTION:When a signal is sent from a circuit equipped to time-division channel device NWO15, switching connection control processor CPO11 exercises connection control service control in the form of a logical signal, but when a connection of a channel is to be made, the channel driving order of driving NWO15 is generated by CPO11 and sent to NWO15 direct. On receiving this order, NWO15 drives the switching of its channel immediately to inform CPO11 of the completion of the execution and then enters the next control. For the communication of CPO11 with trunk control processor TKPO13, on the other hand, the logical signal is sent and analyzed by TKPO13 to control digital signal processor 14, thereby sendig a signal to a circuit via the channel.
