ABSTRACT OF THE DISCLOSURE Disclosed is a fault location system for a repeatered PCM trans- mission system. A first means transmits through a repeatered transmission line, fault location codes based on pseudo-random codes. The fault location codes are capable of code conversion into codes having two states controllable in response to a repeater-designation frequency signal, one of said two states having the occurrence probability of digit "1" equal to k sufficiently greater or smaller than 0.5 while the other state has the occurrence probab- ility of digit "1" equal to (1-k). A second means is disposed at a designat- ed repeater for receiving the fault location codes including repeater trans- mission errors. A third means is provided for extracting a component of the repeater-designation frequency signal from the received fault location codes by means of a fault locating circuit built in the repeater and including an additional code-converter. A fourth means receives the extracted repeater- designation frequency signal component at a transmitting point of the fault location codes, whereby the fault location for the repeatered transmission line is achieved.
