Abstract
PURPOSE:To perform the forced control of the terminal unit in failure, by providing the operating unit composed of the means to detect the call-out of the terminal unit in failure, means to form the forced control signal at return signal transmission time band, and means of short circuit between the private two-cored cables with this signal. CONSTITUTION:The operation unit 12 is provided with the private two-cored cable 2 of the time sharing multiplex transmission remote control unit. In this operating unit 12, the control signal from the central control unit 1 is received, the logic circuit section 7 detects the call-out of the terminal unit in failure, the forced control signal is formed at the forced control signal forming section at the return signal delivery time band from the terminal unit in failure, the private two-cored cable 2 is in short circuit via the microresistor R2 with this signal, and on the exclusive two- cored cable 2, the forced control signal in voltage mode possible for detection with the logic circuit of the terminal unit can be produced.
