Abstract

Dans le cadre de l'augmentation constante des vitesses de transmission se fait ressentir le besoin d'appliquer des techniques de transmission qui permettent une exploitation optimale du moyen de transmission concerné. Dans la zone de raccordement d'abonné, on utilise, comme moyen de transmission, un câble. Les débits de transmission doivent être alors adaptés à la largeur de bande du câble, même pendant le fonctionnement. Les procédés de transmission mis en oeuvre dans l'état antérieur ne peuvent être adaptés à ces exigences qu'avec certaines réserves. L'invention permet de palier cet inconvénient par le fait que des signaux d'information (D) et des signaux de commande (SCM) sont transmis dans une structure à trames à des vitesses pouvant être réglées de façon variable, et par le fait que les signaux de commande (M) peuvent être utilisés pour l'adaptation de la vitesse de transmission au câble et aux besoins de l'abonné.
