Abstract

PURPOSE:To monitor a state, and select and control an apparatus to be controlled, by a repeater, when a fault has occurred in the receiver or the signal line, by monitoring the receiver and the state of the signal line connecting the receiver and the repeater, by each repeater. CONSTITUTION:The repeaters T1-Tn consist of a modulator and demodulator 3, a deserializer 2, a control decision part 4, an automatic address memory part 5, an input gate 6, a control signal output part 7, a monitoring control means 8, and an output switching part 9, and are connected to the receiver Re through the main signal line l0 and also are connected to the terminal equipment through the signal lines l11-l1n, l21-l2n. The receiver Re or a fault detection means for detecting a fault of the main signal line l0 is provided in the control decision part 4, and when a fault has been detected, a state of the emergency state detector connected with the repeater is monitored by the monitoring control means 8, and when an emergency stage has occurred, a necessary apparatus among the apparatuses to be controlled is selected and controlled.
