PURPOSE:To reduce the processing burden of the processor and the software, by switching non-talking signals, such as monitor signals corresponding to each talking channel, etc. together with the talk signals. CONSTITUTION:Among non-talking signals, such as monitor signals for signals A, B, etc., separated at PCM terminal equipment, a parity signal from a code generator PG, etc., 1-bit signals corresponding to each talking channel selected by a selector SEL are inputted into a talking memory SPME of an incoming time switch TSWFn together with a parallel talk signal DL from an incoming highway HWFn. Incoming and outgoing time switches TSWF1-n and TSWB1-n and a space switch SSW constitute a well known time division talking channel network of the T-S-T constitution, and the above-mentioned non-talking signals, such as monitor signal, etc., are simulataneously exchanged with the talk signals through this channel network and outputted to a prescribed time slot of a prescribed outgoing highway HWB1-n. |
