Abstract
PURPOSE:To make maintenance efficient, by transmitting a test signal for operations of a fault detecting circuit of a radio equipment from a control desk. CONSTITUTION:When an indication reporting a fault of a radio equipment comes to a control desk or the like during operating, a test signal 11 which has information for discriminating plural preliminarily prepared fault detection levels is transmitted to this radio equipment by a voice in-band signal or a contact signal, and a test signal control circuit 10 discriminates this test signal 11 and transmits a fault detection level set signal 12 to a fault detecting circuit 9 with the contact signal or a volt age signal to designate an optional one of fault detection levels prepared preliminarily in the fault detecting circuit 9, and the change of the output of a fault signal 7 is supervised in the control desk by presence or absence of an external output fault signal 8, thus discriminating whether the fault is a fault of the radio equipment or not.
