A method and apparatus that will detect the presence of terminations in an ADSL environment is presented. The presently disclosed method and apparatus applies a slowly ramped voltage to the subscriber loop while measuring the current flow. The ramped voltage is able to pass through the inductors. The rate of current flow is discernible as the zener diodes of the Half Ringer, the Premises Splitter, and any Electronic Ringer start to conduct. Thus the detection in time (voltage) of devices that may be on the line under test is achieved. By analysis of a graph of the current in the line as the ramped voltage is applied, changes in the graph provide an indication that a termination is present. The location of the change in current with respect to the applied voltage provides an indication of the type of termination detected.

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.
