Abstract
L'invention concerne primo un multiplexeur qui sert, au cours d'un processus de multiplexage, à sélectionner un signal de sortie parmi plusieurs signaux d'entrée, secundo une unité de commutation de secours qui comporte ledit démultiplexeur et tertio un réseau de télécommunications comportant ladite unité de commutation de secours, ledit multiplexeur ayant une sortie (OUT+, OUT-) et au moins deux entrées (IN+, IN-, IN2+, IN2-) qui reçoivent chacun un signal d'entrée respectif. Un premier point de connexion (IN1+, IN2+) au niveau de chaque entrée est relié à une première ligne de transmissions (TLINE_1) par l'intermédiaire d'un premier dispositif manoeuvrable d'acheminement des signaux (Q1, Q2). Un organe de commutation à commande externe (S2, S1) est également relié à chaque sortie pour l'acheminement d'un signal ou au moins d'une partie de signal reçu au niveau de ladite entrée vers une première ligne de transmission (TLINE_1). Cette première ligne de transmission (TLINE_1) est reliée à un premier point de connexion (OUT+) de la sortie, où l'on obtient un signal de bonne qualité.
