Abstract

PURPOSE:To realize an increment of the transmission output only when the transmission line has a fault, by increasing the transmission output after detecting that the fault of reception at the distant station is due to the transmission line. CONSTITUTION:The incoming field fault detection parts DA and DB are provided to a radio circuit. Then the transmission frequencies are set at f1 and f2 for the stations A and B, respectively. In this case, the effect of attenuation due to a reinfall may have a correlation to the frequecies f1 and f2 in case the transmission line has a fault. Thus when a terminating reduction of f2 is detected at the station A, f1 is reduced in the same way at the station B. Accordingly in case a transmission output increment command is given to the station A from B owing to the incoming reduction at the station B, the incoming reduction is detected at the station B to transmit the information of transmission output increment command to the station A. The station A, before carrying out an increment of output, detects first the reception field of its own station at the detection part DA. If a reduction less than the prescribed value is detected in the detection signal, a transmission line fault is decided. Thus an increment is started for the transmission output.
