Abstract

L'invention concerne un appareil de transmission de données et un procédé permettant à un seul modem, situé en un lieu d'exploitation principal, de traiter plusieurs modems DSL (ligne d'abonné numérique) connectés à une seule ligne d'abonné. Cet appareil de transmission de données et ce procédé sont mis en oeuvre par l'intermédiaire d'une logique réalisant uniquement des séquences de programme périodiques prédéterminées. Ces séquences comprennent la transmission de paquets de plusieurs modems DSL directement connectés, en un endroit, à une seule ligne d'abonné, afin de fournir simultanément des sessions de transmission de données par l'intermédiaire d'un seul modem DSL au central de la ligne d'abonné.
