Abstract

PURPOSE:To detect the generation of a trouble at a radio connecting device with a radio line control device by diagnosing a communication trouble at a radio connecting device by the instruction from the radio line control device side and transmitting the result to the radio line control device side. CONSTITUTION:When a trouble diagnosing action is started, a central control unit 10 of a radio line control device 1 controls a polarity inversion generating part 211 and polling is executed to a radio connecting device 61. At the radio connecting device 61 side, a polarity inversion detecting circuit 311 detects the presence and absence of the polarity inversion, and when the polling is executed, a trouble diagnosing part 311 is activated, and a trouble diagnosing part 321 executes the diagnosis by the loop checking and the voltage checking. A direct current loop opening closing circuit 331, when the trouble is absent, closes a direct current loop, responds to the radio line control device, and when the trouble is present, the direct current loop is released as it is and completion is obtained.
