Abstract

a. L'invention concerne un circuit d'interface de lignes à division temporelle. b. Il comporte un micro-processeur qui fonctionne en synchronisme avec des données reçues sur une ligne de transmission, et fonctionnant selon un programme structuré de manière à desservir des lignes entrantes et sortantes en modulation par impulsions codées sur une base périodique et en synchronisme avec le débit binaire des informations entrantes. c. L'invention s'applique notamment à la liaison de centraux téléphoniques par des lignes fonctionnant en multiplexage par division temporelle.
