ABSTRACT:
A signal distribution signal for a time-division exchange has a distributed control architecture. Its switching network is organized as a plurality of independent planes (RXA to RXD) with terminal units (UT) and control units (UC) are connected via multiplex links (MX) and are synchronized by a time base (BDG) via clock signal distribution modules (MD). Each terminal or control unit is connected both to the switching network and to the clock signal distribution means by at least two independent parallel connections (F1, F2) each of which comprises multiplex links (MX) connected to different planes of the switching network, and at least one distribution link (D) connected to a different distribution module (MD) for each of said parallel connections connected to a given unit. Such exchanges are used for telecommunications purposes.
