ABSTRACT:
The invention concerns regenerative repeaters for pulses. The method consists of detecting errors, coding them and recording them in a channel of a tele-locating frame. Each regenerative repeater of a connection has a channel which is attributed to it, for example channel i, for the repeater whose order is i. The device implementing the method comprises means for directing the tele-locating signals at the input of the repeater, memorizing them and applying them to a low-frequency modulator which reinjects them into a directing means at the output of the repeater; it comprises also means for detecting the channel whose order is i and recording therein the coded proportion of error of the repeater.
