Title
(EN) METHOD FOR QUALIFYING A LOOP FOR DSL SERVICE
(FR) PROCEDE POUR QUALIFIER UNE LIGNE DE SERVICE DE LIGNE D'ABONNE NUMERIQUE
Abstract
(EN)
A method for qualifying a local loop for digital subscriber line service utilizes a test device (12) connected to the customer end of the loop (16) to measure test signals originating from the provider end of the loop (34). An output for the loop qualification test device is based on the measured test signal.
(FR)
L'invention concerne un procédé pour qualifier une ligne de service de ligne d'abonné numérique, qui utilise un dispositif d'essai (12) connecté à l'extrémité client de la ligne (16) pour mesurer des signaux d'essai provenant de l'extrémité fournisseur de la ligne (34). Un signal de sortie du dispositif d'essai de qualification de ligne est basé sur le signal d'essai mesuré.
