Cette invention a pour objet un procédé servant à réaliser une liaison d'établissement avec une faible vitesse non normale sur une seule paire de lignes d'abonnés numériques à grande vitesse. Le procédé comprend les étapes consistant à : déterminer si la vitesse de la liaison d'établissement nécessaire est inférieure à la vitesse de la liaison d'établissement la plus faible ; si oui, alors établir une liaison avec la vitesse normale de la liaison d'établissement la plus faible et définir une configuration de la vitesse faible. L'invention concerne également un appareil servant à réaliser une liaison d'établissement avec une faible vitesse non normale sur une seule paire de lignes d'abonnés numériques à grande vitesse.
