Abstract

L'invention concerne un procédé pour contrôler les parties centrales d'une unité de démultiplexage/multiplexage. Selon ce procédé, un mot d'identification de trame émis par l'unité d'interconnexion pour la synchronisation du compteur de canaux du démultiplexeur/multiplexeur D/M est transmis par l'intermédiaire des parties centrales FZ, LS du démultiplexeur/multiplexeur à la partie décentralisée FDO de ce dernier, puis est renvoyé en direction du circuit d'identification de trame RED de l'unité d'interconnexion, des voies de transmission d'informations existant entre l'unité de commande centrale et l'unité d'interconnexion étant utilisées pour l'envoi de signalisations d'erreurs ou de défauts. Application notamment aux systèmes de télécommunication à multiplexage temporel PCM.
