Abstract: A remote control system for a telecommunications link between two stations, one being a monitoring station and the other a monitored station, interconnected by an outward channel and a return channel, said channels having a plurality of signal regenerating member pairs. The monitoring station comprises means for transmitting by a low frequency channel and in the outward direction a sequence of P pulses, a control circuit being placed in each pair of regenerating members and comprising means for detecting the pulses received, for counting the number n of said pulses, for comparing this number with two predetermined numbers n.sub.1 and n.sub.3 with n.sub.3 .noteq.0 and n.sub.3 <n.sub.1 and when n.gtoreq.n.sub.1, transmitting to a first output n-n.sub.2 the pulses received and when n.sub.3 <n<n.sub.1 transmitting to a second output the control order and transmitting no pulse to the first output, the number P of pulses transmitted by the monitoring station being selected equal to Nn.sub.2 +n.sub.
