PURPOSE:To give no effect of a fault of a certain transmission system to other transmission systems by providing gate means corresponding to each transmission system at the input side of a means which performs the distribution connection and the OR connection with plural transmission systems. CONSTITUTION:The transmission signal 2 of a signal transmitter 1 is distributed to predrivers 11, 41 and 51 which are gated with the output of a latch circuit 201 for transmission systems corresponding to bits and then led to transmission lines 211a, 221a and 231a from transmission/reception parts 21, 22 and 23. While the reception signals sent from transmission lines 212a, 222a and 232a are received by a reception signal line 3 via prereceivers 32, 42 and 52 which are gated by the output of the circuit 201 and through an OR circuit 101. In case, a fault arises at the part 21, the prereceiver 32 is inhibited to ensure the normal reception of the reception data from parts 22 and 23. |
