Abstract

L'invention concerne un dispositif de commande de modem pour commuter automatiquement et gérer sans erreurs l'émission et la réception de signaux vocaux, de signaux de données standard, de signaux de télécopieurs, transmis par une ligne d'un réseau téléphonique, par des réseaux de communication radio, des systèmes satellites (118) ainsi que dans des réseaux téléphoniques cellulaires (108). Le dispositif comporte des commutateurs analogiques (70, 74, 88) qui reçoivent des signaux de commande depuis un microprocesseur (10) pour assurer la commande et la commutation des chemins audio ou de données, d'une plaquette vocale interne.
