Abstract

PURPOSE:To independently execute local call processing of a line concentration stage, by providing a separating gate and a multiplexing gate on the output side of a time switch in the up direction and the input side of a time switch in the down direction, respectively. CONSTITUTION:As for a time switch of the up-side, a digital signal whose input multiplexing degree J is inputted to a service memory BFMF, and a digital signal of a channel J is outputted under the control of a control memory CTLMF. In accordance with this output signal, a channel K and a channel L are connected to the distribution stage side and a multiplexing gate GB of the down- side, respectively, by a separating gate GB. Gate control of the channels K, J is fixedly assigned by a counter CTR. On the other hand, as for a time switch of the down-side, the channel K is inputted from the distribution stage, is multiplexed with a channel L of the up-side switch by the gate GB, the channel J is inputted to the service memory BFMB, is switched by the control memory CTMB, and the channel J is outputted.
