Abstract

PURPOSE:To prevent the system down, by discriminating always the presence or the absence of a guard time during operation of a transmitter and by discriminating a fault of the transmitter to stop the power supply to this transmitter when no guard time occurs within a constant time. CONSTITUTION:A transmitter 1 transmits the transmission power by the power supply from a power supply circuit 5. A part of the transmission power is inputted to a transmission power detecting circuit 3 through a transmission coupler 2. The transmission power detecting circuit 3 gives a turning-on or off signal, which corresponds to guard times G1, G2- set between time slots T1, T2- and time slots T1, T2-, to a discriminating circuit 4 for the presence or the absence of guard time which consists of a flip flop. When this discriminating circuit 4 discriminates the absence of the guard time, the power supply circuit 5 is controlled through a control line 14 to stop the power supply to the transmitter 1. Thus, the interference with another transmitter is eliminated to prevent the system down.
