Abstract

PURPOSE:To save labor and to detect a fault in the form of a transmission in-use state, by automatically inspecting each communication circuit line by selecting a channel from a central base station. CONSTITUTION:An antenna signal is sent from a car telephone exchange 7 to K radio base stations Si-Si+k-1 to make their channels usable. Then, (i)s is base stations Si-Si+k-1 are varied from 1 to (n) to change usable channels successively and one of the remaining channels is regarded as a channel to be tested to send a control signal for circuit connection from the exchange 7 to a radio base station 5 in charge of the channel. Consequently, an artificial mobile station 1 and the exchange 7 are connected mutually through the radio base station 5. Then, the radio base station 5 sends a control signal to the artificial mobile station 1, which sends the same signal, as it is, to the car telephone exchange 7 through the radio base station 5 as a circuit monitoring signal.
