Abstract

PURPOSE:To decrease the number of the timing control lines as well as to facilitate the high-speed operation by installing dispersively various types of control counters concerning the timing control at each part and then carrying out the control between the timing control part and decentralized counters only by the synchronous signal. CONSTITUTION:The time-division talking device operating with the fixed clock frequency and under the prescribed phase conditions is constituted with the following component parts: multiplication part 7 combining the incoming and outgoing highways; isolation part 8; time switches 1 and 3 connected to control memories 4-6; space switch 2; and timing control part 9 each. Then CPU11 is connected to memories 4 and 6, and phase control counters 14-18 which count the phase control information against memories 4-6 plus parts 7 and 8 are connected to part 9. And the phase control information given from basic counter 10 connected to part 9 is supplied in a fixed cycle to maintain the phase relation among the function process parts within the talking device. Then counters 14-18 plus memories 4-6 are formed into the module to decrease the number of the control lines.
