Abstract: PURPOSE: An error restoring apparatus of an IPC path in an ATM switching system is provided to use an IPC path for transmitting and receiving a data without interruption by detecting a troubled status and automatically performing duplex switching by an IPC board in case that there occurs an error in a communication port of a processor or of an IPC board by constructing an error detect circuit in the IPC board performing an IPC(Inter Processor Communication). CONSTITUTION: A watchdog sensing circuit(110) senses a watchdog signal transmitted from a processor(20), which includes two OR gates, one AND gate and two NOR gates. If the watchdog signal sensing circuit(110) detects a normal watchdog signal of '0001' from the processor(20), it outputs an output value '0'. If the watchdog signal sensing circuit fails to detect a watchdog signal from ports, it outputs an output value '1'. A cable disturbance processing unit(120) detects release of a cable which connects the processor(20) and an IPC board(100). The cable failure processing unit(120) grounds one end of the cable and connects the lower end of the cable to the power source(Vcc), so as to render the output value '0' when the cable is normal in a state that the processor(20) and the IPC board(100) are connected, or so as to render the output value '1' if the cable is released, thereby sensing release of the cable. A duplexing determining unit(130) operates the output value of the watchdog signal sensing circuit(110) and the output values of the cable failure processing unit(120) by means of a circuit provided therein and performs duplex switching according to the operation result. The duplex determining unit(130) includes an AND gate and an OR gate. The AND gate ANDs the output values applied from the cable failure processing unit(120), and the OR gate ORs the output value of the watchdog signal sensing circuit(110) and the output value of the AND gate, and outputs a final output signal. The duplex determining unit(130) outputs the final output signal periodically, and if an output value '1' signifying an abnormal state is detected, the duplex determining unit(130) resets a switching board to perform the IPC board duplex switching.
