CA 2203276

The invention provides a method and apparatus for testing a telecommunications network (1 to 12) in order to determine an approximate location of a fault. The method comprises measuring a change in capacitance of a line in the network and then determining from a known ratio of capacitance to length of line a length of line that corresponds to that change. This length will give an approximate location of a fault from a subscriber's equipment located at premises (1).

L'invention concerne un procédé et un appareil pour tester un réseau de télécommunications (1 à 12) afin de déterminer un emplacement approximatif d'un défaut. Le procédé consiste à mesurer un changement de la capacité d'une ligne dans le réseau et ensuite à déterminer, à partir d'un rapport connu entre la capacité et la longueur d'une ligne, une longueur de ligne qui correspond à ce changement; Cette longueur va donner un emplacement approximatif d'un défaut à partir d'un équipement d'abonné se trouvant dans les locaux (1).
