ABSTRACT:
For a digital communication system comprising a plurality of repeaters between two terminals from one of which the repeaters are to be selectively controllable for fault-location or remote-control purposes, repeaters are disclosed each of which has its address stored unalterably in its address memory, so that the address resembles a serial number as is commonly used as an equipment identification. This saves any adjustment work during the installation of repeaters into the communication system. Also disclosed is a fault finder for such a communication system which is capable of successively interrogating the repeaters in the system for their addresses and their locations in the system, and of writing these addresses together with the associated locations into a memory. The repeaters then contain suitable devices which cooperate with this fault finder.
