PURPOSE:To the throughput by controlling a titled system by a processor for governing one partial talking device when making a connecting path in said device, and by processors of both devices in case of extending over two devices, in a dispersion control type switcheboard. CONSTITUTION:Partial talking devices NW1-NW3 are governed by processors CPR1-CPR3, respectively, and as for telephone sets S1-S6 contained in an all channel device SPNW, one or two pieces in the partial talking devices operate together and a channel is set between each other. As for each telephone set, a prescribed time slot is assigned, and watching channel maps CM1-CM3 for holding time slot idle-busy information existing in each main memory MM1- MM3, each processor CPR1-CPR3 forms a channel by selecting intermediate outgoing highways M1-M6 and intermediate incoming highways M'1-M'6. Accordingly, a load of a main processor MPR can be reduced. |
