Abstract

L'invention concerne un procédé et des dispositifs permettant de faire fonctionner un poste d'abonné avec un débit de données de 32kB/s par canal, de préférence d'une installation radiotéléphonique privée, sur une installation téléphonique privée numérique, par l'intermédiaire d'une interface SO, qui comprend deux canaux B de chacun 64kB/s par direction. Chacun des canaux B de l'interface SO sont divisés avec multiplexage dans le temps, en deux canaux de 32kB/s qui comprennent des signaux à modulation par impulsion et codage différentielle (signaux MICDA).
