ABSTRACT:
A time-division-multiplexing loop telecommunication system has a first and a second transmission line for linking up a succession of connecting circuits and for supplying information, in a normal service direction of transmission, to subscriber circuits attached to the connecting circuits; these connecting circuits are provided with an input and an output for the connection of subscriber circuits, with up-line and down-line access points connected to the said lines. Typical of this system is that at the level of each connecting circuit provision is made for means of command for linking the input of the subscriber circuits to one of the up-line access points receiving the infromation, while the output is linked to the down-line access points.
