摘要： A node device for switching the system in operation to an auxiliary system when the system fails, wherein a relative phase difference determining section determines the relative phase difference between the transmission delays of the transmission line in use and the auxiliary transmission line to find which the node device or the transmission line has failed degrading the transmission quality, a path error detecting section detects an error of the path through the transmission lines, a main signal error calculating section calculates the error of the main signal transmitted through the transmission lines so as to locate the part where the failure has occurred on the basis of the relative phase difference and the results of the detection of the path error and the calculation of the error of the main signal.
