Abstract
A method and an arrangement for the address-free fault locating by means of loop closure for a message transmission link which contains regenerating and/or amplifying intermediate stations in specific spacings provides that transmission links of this sort are monitored such that, from a locating end station, in a distant intermediate station, a connection is completed from the one to the other transmission direction and via this connection, test signals are transmitted. For the saving of the switches which separate the further link parts, the transmission of the loop closure signal is interrupted for a specific characteristic duration. The method according to the invention and the corresponding arrangement are in particular suited for insertion in light wave-guide transmission systems.
