Abstract

a. Réseau de commutation numérique à division du temps commutant des voies numériques isochrones ayant des débits différents mais sous-multiples d'un débit prédéterminé. b. Les bits en phase transmis par les voies entrantes qui ont un état binaire prédéterminé sont détectés et correspondent à la transmission sur la voie multiplex intermédiaire des adresses des voies sortantes reliées respectivement aux voies entrantes. L'information inhérente à l'état d'un bit de voie entrante est transmis implicitement par la présence ou l'absence de l'adresse explicite de la voie sortante correspondante. Chaque trame récurrente de la voie multiplex est composée d'un nombre d'adresses de voies sortantes statistiquement au plus égal à la moitié du nombre de voies entrantes. Du côté de la partie émission d'une voie sortante, la détection de l'adresse de la voie sortante correspond à la transmission d'un bit à l'état prédéterminé et l'absence d'une telle détection correspond à la transmission d'un bit à l'autre état binaire. c. Commutation numérique.
