Abstract

PURPOSE:To secure a quick detection for the fault of the receiver, by providing the receiving switch between the branching filter and the receiver and then giving the switching control to the receiving switch with the output of the detector. CONSTITUTION:When detector 32 detects the relative change of the signals showing the state of the received signals delivered from receivers 41 and 42 each, the received signals supplied to receivers 41 and 42 which gave the switching to receiving switch 34 are first converted to each other to decide whether some fault occurs at receivers 41 and 42. And transmitting switch 31 is switched only when no occurrence of the fault is decided. In case some fault is detected by detector 32, no switching is given but the occurrence of the fault is informed.
