ABSTRACT:
A fault tolerant communication apparatus provided with balanced type transmission lines composed of first and second complementary transmission lines respectively transmitting first and second communication signals of different polarity, a transmission device for transmitting the first and second complementary communication signals through the balanced type transmission lines, a reception device for receiving the first and second complementary communication signals through the balanced type transmission lines and for receiving contents of a communication based on the complementary relation between the first and second communication signals, and a failure detection circuit for determining whether or not each of the first and second transmission lines fails. The failure detection circuit is provided with a first judgement device for monitoring the second transmission line according to the first communication signal, for resetting a second-transmission-line monitoring state, in which the second transmission line is monitored, in response to the second communication signal and for judging whether or not the second transmission line fails, on the basis of a fact that the second-transmission-line monitoring state continues for a predetermined period of time, and a second judgement device for monitoring the first transmission line according to the second communication signal, for resetting a first-transmission-line monitoring state, in which the first transmission line is monitored, in response to the first communication signal and for judging whether or not the first transmission line fails, on the basis of a fact that the first-transmission-line monitoring state continues for a predetermined period of time.
