PURPOSE:To switch successively plural outputs of service interruption by a circuit and to receive the service interruption information with a receiver, by providing a circuit switching part which works independently of the reception processing of telemeter data and said receiver within a master station. CONSTITUTION:Plural slave stations K1-Kn are connected to a master station M by circuits l1-ln. The data sent from telemeter transmitting parts A1-An of slave stations K1-Kn are received with successive switching performed by circuits A1-An at a circuit switching part 1 and processed at a telemeter data receiving part 6. When a service interruption is detected at a service interruption signal receiver 5, circuit switch control parts 2 and 4 are actuated by the service interruption detecting signal. Then the service interruption and reception are processed while the circuits l1-ln are switched at a circuit switching part 3. The outputs of service interruption information of stations K1-Kn are successively switched, and the service interruption information is received by a receiver 5 and processed. |
