Abstract
Salient features of a novel automatic fault location scheme for remote supervision of repeatered digital transmission lines is discussed. Looping back repeaters in succession by a single command on the power feed line eliminates the use of a separate supervisory cable pair. The scheme has been generalized in such a way as to facilitate its adoption to almost all type of repeaters, thus providing an inexpensive,simple supervisory scheme for a low density rural area line transmission hookups.
