Abstract
Ce dispositif de communication entre un adaptateur numérique (5) relié à un central (4) par l'intermédiaire d'une interface numérique (7), notamment de type RNIS, et un adaptateur analogique (6) relié à un central (3) par l'intermédiaire d'une interface analogique (8), lesdits centraux (3, 4) étant reliés par l'intermédiaire d'un réseau de télécommunications (2), est caractérisé en ce qu'il comporte des moyens (11, 12; 15, 16) de liaison directe entre l'adaptateur numérique (5) et l'adaptateur analogique (6), l'information numérique de l'adaptateur numérique (5) étant envoyée à l'adaptateur analogique (6), et réciproquement, sous forme numérique sans émuler un signal analogique.
