Abstract

PURPOSE:To simplify the circuit constitution with just one unit of the control pulse needed by providing several data transmission parts to send out the pulse-converted data and the counter part to the data transmission device and then actuating the transmission part of the next stage when the head transmission part finishes the data transmission. CONSTITUTION:The channel bank is formed with single channel codices 2-6, supervisory unit 7 and the PCM common bus line each. And each of codices 2-6 is constituted with inverters 8 and 9, shift registers 10 and 11, AND gate 12, JK flip-flop 13, D filip-flop 14 and tristate gate 15 each. In such constitution, the control signal is applied from outside. Thus codex 1 transmits the 8-bit data via registers 10 and 11 to apply this output to next codex 2. In the same way, final codex 6 is actuated, and this output state is compared by unit 7 to decide the normal or abnormal state for the bank.
