The present invention provides a method of detecting and correcting a fault in a signal transmission system. The method for detecting and correcting signal transmission faults in a signal transmission system includes bi-directional signaling on the same fiber, cable or signal line. A fault in a transmitted signal from a first upstream node to a second downstream node is determined by the loss or degradation of a signal simultaneously transmitted from the second downstream node to the first upstream node transmitted in the opposite on the same cable, signal line, or optical fiber. As a result, the aggregate propagation delay of the transmitted signals necessary for fault detection and fault notification is reduced and the amount of time to detect a fault and restore fault free signal transmission between one node and another node in a signal transmission systems is reduced, thereby increasing user satisfaction with minimal signal transmission interruptions even in the case of a transmission line fault. Further, a transmission line fault may be detected prior to transmission of a desired signal so that an alternate traffic route may be predetermined before transmission of the desired signal.
