Abstract

PURPOSE: To secure detection of the faulty sectin in a short time by carrying out the remote monitor control for the unmanned station only when the additional unit for manned switching station receives the earth input from the squelch control key of the circuit corresponding to the circuit control unit.
CONSTITUTION: The manned station additional unit 15 of a circuit transmits the earth output to remote monitor control unit 12 only when the earth input is supplied from both the circuit control unit 11 and squelch control key 17 of the corresponding circuit. The earth applied to unit 12 is transferred in the form of the earth of unmanned station remote control unit 13 of the unattended station which is selected through the remote monitor control system and then applied as the input of unattended station additional unit 16 to control the squelch of radio repeating equipment 10. Thus, the faulty section can be detected in a short time
