Abstract
Réseau de connexion numérique à plusieurs étages de modules de commutation identiques. Chaque module est un réseau de connexion sans blocage entre plusieurs multiplex entrants (de préférence 16) et le même nombre de multiplex sortants. Un réseau replié de grande capacité, par exemple jusqu'à 16 groupes de 64 lignes multiplex bidirectionnelles 26, est obtenu avec deux étages identiques dans lesquels chaque module constitue deux matrices 8 x 8 (une dans chaque sens) et un troisième étage à un seul côté comportant deux fois moins de modules. Les signaux de commande utilisés pour établir les connexions sont multiplexés avec les signaux relatifs aux communications déjà établies. Les connexions peuvent être réfléchies par un module quelconque, de sorte qu'un nombre minimum d'étages est utilisé pour chaque communication. Application aux systèmes téléphoniques à modulation par impu sions et Codage
