A system and method for testing a modem of a digital subscriber line access multiplexer (DSLAM) includes a pair of modems communicatively coupled to each other by way of a communications path that includes a first DSL communication medium connected to one modem, a second DSL communication medium connected to the other modem, which is part of the DSLAM, and an Ethernet medium connected between the first and second DSL modems. DSL signals can be dispatched from the first (or second) modem via the first (or second) DSL communication medium for receipt by the second (or first) DSL modem via the second (or first) DSL communication medium, whereupon, DSL signals passing from the first DSL communication medium to the second DSL communication medium, or vice versa, are converted into Ethernet packets for transmission over the Ethernet medium and then back into DSL signals.
L'invention concerne un système et un procédé pour tester un modem d'un multiplexeur d'accès de ligne d'abonné numérique (DSLAM) comprenant une paire de modems couplés de manière communicante l'un à l'autre au moyen d'un chemin de communication qui comprend un premier support de communication DSL connecté à un modem, un second support de communication DSL connecté à l'autre modem, qui fait partie du DSLAM, et un support Ethernet connecté entre les premier et second modems DSL. Des signaux DSL peuvent être expédiés depuis le premier (ou second) modem par l'intermédiaire du premier (ou second) support de communication DSL pour être reçus par le second (ou premier) modem DSL par l'intermédiaire du second (ou premier) support de communication DSL, après quoi des signaux DSL passant du premier support de communication DSL au second support de communication DSL, ou vice versa, sont convertis en des paquets Ethernet pour être transmis sur le support Ethernet puis reconvertis en des signaux DSL.
