Abstract

PURPOSE:To independently execute switching control in a time switch, by providing 2 channel memories in the up and down directions, respectively, and connecting each multiplexing channel portion of each time switch. CONSTITUTION:As for channel memories BFMF1, BFMF2 having input multiplexing degree J and output multiplexing degree J, a digital service signal of input multiplexing degree J is inputted to both of them, and a signal of multiplexing degree J controlled by a switch control memory CTLMF is outputted. Also, in the down-direction, channel memories BFMB1, BFMB2 having input multiplexing degree J and output multiplexing degree J are provided, an output signal of multiplexing degree J of the memory BFMF2 is led to the input side of the memory BFMB1, an output controlled by the switch control memory CTLMB becomes common in the memories BFMB1, BFMB2, and becomes a channel signal having multiplexing degree J. Accordingly, the switching control can be executed independently from other switch module.
