Abstract

Elément de commutation numérique assurant le transfert de données des voies temporelles de plusieurs multiplex entrants dans des voies sélectionnées de plusieurs multiplex sortants. Selon une réalisation préférentielle de l'invention, l'élément comporte 16 ports pour commuter des multiplex de 32 voies à 16 éléments binaires. Chaque port comporte une logique de réception 304 d'un multiplex entrant 308 et une logique d'émission 306 d'un multiplex sortant 310. Les ports ont accès cycliquement à un bus multiplex 302 qui permet le transfert en parallèle des données entrantes aux logiques d'émission appropriées, en utilisant un intervalle de temps d'élément binaire pour chaque transfert. Chaque logique d'émission comporte une mémoire de données à 32 adresses pour assurer le changement de voie requis. Les commandes de sélection sont reçues dans les voies entrantes et identifiées par les logiques de réception qui comportent les mémoires nécessaires à l'enregistrement du port et de la voie destinataires pour chaque voie entrante. Application aux systèmes téléphoniques à modulation par impulsions et codage.
