断用搬送端局装置の点検回路。A check signal generation circuit that outputs a pulse of a certain width at a certain period is connected to the FL signal control gate input of the transmission terminal device for transfer cutoff in parallel with the transmission control contact input information, and a check signal of a certain width is generated at a certain period. By connecting a timer that uses the noise detection circuit output signal of the transmitting terminal device that sends out the signal and the receiving terminal device that interrupts transfer as a reset signal, automatic inspection can be performed between the transmitting terminal device and the receiving terminal device. Inspection circuit of carrier end station equipment for transfer cutoff.
