Abstract

Système de commutation numérique à commande répartie pour centre de commutation téléphonique local ou régional dont le nombre d'abonnés et de circuits doit pouvoir être accru régulièrement par extension modulaire. Les interfaces 128 des circuits 134 et lignes analogiques 132 comportent chacune un microprocesseur associé à une mémoire et sont groupées par unités de lignes comportant une mémoire partagée par les microprocesseurs de la même unité. Chaque unité comporte un mutiplexeur-démultiplexeur relié à un réseau de connexion temporel 102 par un ou plusieurs canaux multiplex 204 et une interface générale. Les signaux de parole codés en modulation DELTA ou MIC sont multiplexés avec les signaux de sélection fournis par les microprocesseurs traitant séparément les lignes appelantes et les lignes appelées.
