ABSTRACT:
A remote control method and system controlling a radio unit so as to readily specify a portion where a failure occurs, and to quickly take recovery measures against the failure includes a supervisory unit located in the vicinity of the radio unit. If abnormality occurs in the operation of the supervisory unit, an alarm signal detecting unit monitors an operation of the supervisory unit, and transmits the alarm signal to an abnormal processing signal outputting unit through a communication control line. When the abnormal processing signal outputting unit receives the alarm signal from the alarm detecting unit, it transmits the abnormal processing signal to an abnormal processing unit through the communication control line. When the abnormal processing unit receives the abnormal processing signal from the abnormal processing signal outputting unit, it executes abnormal processing in accordance with the received abnormal processing signal. Thus, if the abnormal processing signal outputting unit receives an alarm signal from the alarm detecting unit, no disconnection occurs in the communication control line. If abnormality occurs in the supervisory unit, it can be readily specified by a remote control unit.
