Abstract

Système de télécommunications à commutation temporelle à extension modulaire. Le module de base utilise un microprocesseur 22 et sa mémoire 24 qui assurent le traitement des communications et pilotent un explorateur distributeur automatique 30 par l'intermédiaire duquel l'unité de traitement 20 est tenue informée des changements d'état des circuits terminaux 12. En associant plusieurs modules, on peut constituer des systèmes de taille variable, moyennant l'adjonction d'un processeur central chargé d'organiser les échanges entre les différents modules. L'invention s'applique notamment à la réalisation d'autocommutateurs téléphoniques de moyenne capacité.
