Abstract

See full text

The invention relates to a method for pinpointing an interruption in a link for transmitting digital signals between a first station and a second station on the basis of the times of occurrence of signal changes on the link. In accordance with the invention, the method is characterised by generating signal changes after the link has been restored. Preferably, the time of restoration is determined on the basis of data signals received, and a detection signal is fed to the link after the determination of the time of restoration. On the basis of the difference in time of observing restoration and of receiving a detection signal, the location of the interruption is determined. For this purpose, the length of the link need not be known.
