Abstract

PURPOSE:In an data transmission system consisting of plural number of stations, a method of find out defective station in such a way, effective even when the real cause of the trouble is difficult to find out, that the all stations have to be bypassed by the relays at first stage of trial then to check the system function by adding stations in operation one by one.
