Abstract
La présente invention concerne un procédé et un appareil détectant la présence de raccordements dans un environnement ADSL. Les procédé et appareil de l'invention appliquent une tension progressive sur la ligne d'abonné tout en mesurant l'écoulement de courant. La tension progressive peut traverser les inducteurs. On peut détecter la vitesse de l'écoulement du courant dès qu'il y'a conduction dans les diodes Zener du circuit demi-sonneur, du circuit diviseur local et de tout circuit sonneur électrique. Ainsi, on détecte dans les temps (tension) les dispositifs présents dans la ligne à l'essai. En analysant le graphe du courant qui traverse la ligne lorsque la tension progressive est appliquée, les modifications du graphe fournissent une indication sur la présence d'un raccordement. L'emplacement de la variation de courant par rapport à la tension appliquée fournit une indication sur le type de raccordement détecté.
