An IPC(Inter Processor Communication) fault management method in a full electronic exchange and a recording medium thereof are provided to confirm fault states of a CDL(Central Data Link), an LDL(Local Data Link), an RI(RASM(Remote Access Switching Module) Interface), and nodes or cables periodically, thus automatic recovery is available without disconnection of an exchanging service even in case of fault. Receiving devices of each node receive test frames to count the number of the received test frames(S2). If the number of the test frames is smaller than the first threshold value, test results are decided as NOK(S6), and the number of NOK times is counted(S8). The receiving devices decide whether the second unit time is reached(S10). If so, and if the number of the NOK times at the time of reaching the second unit time is bigger than the second threshold value, corresponding ports are decided as a fault(S14). Port switching is performed(S16). |
