Abstract

PURPOSE:To increase the usage efficiency of highway, by using a channel memory consisting of separate regions for audio and signal. CONSTITUTION:Incoming and outgoing channel memories SPMF' and SPMB' in a switch module SM' are formed with audio region TSM and signal region NTM, respectively. A multiplex signal from multiplex lines HW-1 and HW-2 is further multiplexed and controlled at a control memory CTLM, and audio and control signals are separately stored at the corresponding location of TSM or NTM channel. The CTLM can indicate whether the channel of the HW-1 and HW-2 is audio or control signal in every channel. Thus, the line corresponding section LM-2' accommodating a PCM line can multiplex 128 lines as they are to all the channels of the HW-2'. As well known, the LM-1' multiplexes subscribers SUB of 120 on the HW-1 with the 8 control channels.
