A fixed station (BFR1) is able to interact with a plurality of independent stations (SA1, . . . , SA4) and is linked to an external management unit (UGRB1) only by the intermediary of a single pair of telephony wires (LT). This management unit (UGRB1) then incorporates the management and monitoring means for the telephony communications, and is linked to the switched telephone network (CTPU) as well as to digital channels (CNPU). Communication between the independent stations (SA1, . . . , SA4) and the fixed terminal (DFR1) is carried out by the intermediary of a plurality of elementary voice channels and of elementary signaling channels while the transmission line (LT) is capable of transporting a voice line channel and a signaling line channel according to a predetermined bidirectional time framing. The terminal and its management unit are then suitable for carrying out multiplexing/demultiplexing between these various channels.
