Abstract

L'invention concerne des équipements de télécommunications et peut s'utiliser pour identifier un port d'un panneau de commutation à travers lequel on effectue la connexion d'un dispositif réseau. Elle permet d'identifier le port ou le câble qui y est connecté et qui sert à la transmission de données par le dispositif réseau sans nécessiter le remplacement ou la transformation de l'intégralité du panneau de commutation. A cet effet, on a doté chacun des capteurs de connexion dont sont munis les ports de communication d'une capacité de recevoir les signaux de rayonnement électromagnétique induit à l'endroit de formation d'une irrégularité dans le conduit de câble; on a disposé chacun des capteurs de connexion près du port correspondant du panneau de commutation à une distance suffisante pour la réception de signaux de rayonnement électromagnétique induit à l'endroit de formation d'une irrégularité dans le conduit de câble lors du branchement du câble, lors de la transmission au moyen de ce câble de signaux correspondants, à une distance de n'importe lequel des autres ports du panneau de commutation qui exclut l'actionnement accidentel des capteurs sous l'effet des signaux de rayonnement électromagnétique induit depuis le conduit de câble vers n'importe lequel de ces autres ports. On a identifié au moyen d'une unité de traitement de données à laquelle sont connectés tous les capteurs de connexion le port déterminé du panneau de commutation au moyen d'un signal provenant du capteur de connexion qui correspond à ce port lors de la réception d'un rayonnement électromagnétique enduit par ce capteur de connexion.
