換装置。[Claims for Utility Model Registration] A digital multiplex converter that multiplexes and inversely converts multiple digital input signals, capable of outputting predetermined pulses during normal use and outputting a constant logic level during testing. In normal use, when the input signal on the transmitting side is input, it is detected and outputted as is, and when the input signal on the transmitting side is unattended, it is detected and the oscillation circuit has a changeover switch. a logic gate circuit that outputs a predetermined pulse of the circuit, detects when the input signal on the transmitting side is unattended during testing, and outputs a constant logic level of the oscillation circuit; ° During normal use, the transmitting side; The input signal or the predetermined pulse is input and multiplexed, and during testing, the constant logic level is detected and reference pulses such as frame pulses can be self-generated. A digital multiplex conversion device characterized by:
