Abstract

Configuration dans laquelle un client de service d'accès à distance (RAS) et un serveur de service d'accès à distance (RAS) peuvent être connectés via un réseau commuté RNIS, qui est complétée de manière qu'une liaison soit établie sur une impulsion de démarrage, transmise par le canal D du réseau commuté RNIS, du serveur RAS au client RAS. L'objet de la présente invention rend possible la transmission de données depuis une entreprise centrale vers une personne effectuant du télétravail, sans intervention de cette dernière.
