ABSTRACT:
The invention relates to a device for the remote adjustment of a switchable network equipping an unattended station on a transmission line, by means of remote control frequencies emitted from a terminal station on this line. The device enables the remote control of a motor actuating a switch which operates said switchable network. The moving of the switch, and then the adjusting of the network, can be followed at the terminal station from the observing of the level of a return frequency sent back from the unattended station to the terminal station.
