Abstract

Système de commutation numérique à réseau de connexion modulaire et à commande par microprocesseurs. Les terminaux desservis par le système sont répartis en groupes (60 lignes ou 30 circuits) à chacun desquels est associé un premier micro-processeur A effectuant une partie des fonctions de traitement nécessaires à ce groupe, par exemple la détection des nouveaux appels et la recherche de trajets de connexion. Les autres fonctions de commande, telles que l'établissement, le maintien et la libération des connexions, sont assurées pour plusieurs groupes A0 à A7 par un second microprocesseur B via un commutateur temporel 42 identique aux modules utilisés dans le réseau de connexion 10. Les signaux de commande des commutateurs, les signaux de parole et les informations échangées entre microprocesseurs sont multiplexés sur des trajets communs 38, 26, etc.
