Abstract

PURPOSE:To reduce the scale of a digital telephone switchboard by preventing the reduction of traffic intensity capacity, by closing all space-division switches in a row or column which corresponds to an input signal highway in a space switch junctor. CONSTITUTION:Signals generated at signal sound sources 141-14m are converted into digital signals, which are arranged in prescribed time slots of frames of signal highways 91 and 92. The frames on those signal highways 91 and 92 are multiplexed by multiplexer 31 and then primary time switch 41 performs time slot interchange a controller assigns. The multiplexed frames are switched by space switch junctor 8, corresponding to respective time slots, for secondary switch modules 51-5n under the control of the controller and, after being demultiplexed, outputted to sound signal highway 15.
