Abstract

Cette invention se rapporte premièrement à un démultiplexeur qui, lors d'un processus de démultiplexage, sélectionne une sortie pour un signal reçu sur une entrée, deuxièment à une unité de commutation de secours qui comporte un tel démultiplexeur et troisièment à un réseau de télécommunications qui comporte une telle unité de commutation de secours, ledit démultiplexeur ayant une entrée (IN+, IN-) et au moins deux sorties (OUT1+, OUT1-, OUT2+, OUT2-). Un premier point de raccordement (IN1+) de l'entrée est relié à une première ligne de transmission (TLINE¿-?1) de façon à ce qu'un signal d'entrée soit acheminé vers ladite ligne. Un premier point de raccordement (OUT1+, OUT2+) au niveau de chaque sortie est relié à la ligne de transmission (TLINE¿_?1) par l'intermédiaire d'un premier dispositif gérable d'acheminement de signaux (Q1, Q2). Un organe de commutation à commande externe (S1, S2) est également relié à chaque sortie. Un organe de commutation (S1) gère l'un desdits premiers dispositifs d'acheminement de signaux (Q1) dans le but d'acheminer le signal qui est porté sur la première ligne de transmission (TLINE¿_?1) vers le premier point de raccordement (OUT1+) d'une sortie sélectionnée.
