-35- ABSTRACT: The time-division-multiplexing loop telecommuni- cation system described comprises a first and a second transmission line (L1 and L2) for linking up a succession of connecting circuits (C0, C1, C2, C3, C4 and C5) and for supplying information, in a normal service direction of transmission, to subscriber circuits (CA1, CA2, CA3, CA4 and CA5) attached to the connecting circuits; these connecting circuits are provided with an input (IN) and an output (OUT) for the connection of subscriber circuits, with up-line (UP1 and UP2) and down-line (DO1 and DO2) access points connected to the said lines (up-line and down-line being defined by the above-mentioned direction of transmission). Typical of this system is that at the level of each connecting circuit provision is made for means of command (PP) for linking the input of the sub- scriber circuits to one of the up-line access points (UP1 or UP2) receiving the information, while the output is linked to the down-line access points (DO1 and DO2).
