A system and method for electronically identifying connections established through a cross-connect system provides for the identification of all hard- wired and temporary patch connections, and any modifications made to existing cross-connect circuit connections. Connection identification and status information is acquired in near real-time and stored in a database which is accessible by a user through a graphical user interface (GUI). The TRACE or lamp wires which connect respective pairs of cross-connect circuits are utilized in an unconventional manner so as to form a scanning bus. The information signal paths established through the cross-connect circuits remain undisturbed. A scanning signal is communicated between each pair of cross- connected circuits over the TRACE conductor. In the event a patch cord is used to temporarily redirect a signal connection, the scanning signal is transmitted over the shield or sleeve conductor of the patch cord. The scanning signal provides identification and other information concerning the transmitting circuit. A circuit receiving the scanning signal communicates its identification information and that of the transmitting circuit derived from the scanning signal to a central computer. The identification information acquired by the central computer from all receiving cross-connect circuits provides identification and status information for all circuits within the cross-connect system. In one embodiment, all circuits of a cross-connect system are scanned and identification information acquired in the time required to transmit a single cross-connect circuit ID bit string, irrespective of the total number of cross-connect circuits included within the cross-connect system.

L'invention concerne un système et un procédé permettant l'identification électronique des connexions établies via un répartiteur: identification de l'ensemble des connexions en câble et des connexions de raccordement temporaires, et de toute modification apportée aux connexions existantes des circuits du répartiteur. On acquiert presque en temps réel les données d'identification et d'état de connexion, avec enregistrement dans une base de données accessible via une interface utilisateur graphique (GUI). Les câbles de TRACE ou de lampe reliant les paires respectives de circuits d'interconnexion sont utilisés de manière non classique pour former un bus de balayage. Les trajets de signaux d'information établis via les circuits d'interconnexion ne sont pas affectés. Un signal de balayage est acheminé entre chaque paire de circuits d'interconnexion via le conducteur TRACE. En cas d'utilisation d'un cordon de raccordement pour réacheminer provisoirement une connexion de signaux, le signal de balayage est transmis sur le blindage ou le manchon du cordon de raccordement. Le signal de balayage fournit l'identification et autres données relatives au circuit d'émission. Un circuit recevant le signal de balayage fournit à un ordinateur central son information d'identification et celle du circuit d'émission issue du signal de balayage. L'information d'identification acquise par l'ordinateur central depuis tous les circuits d'interconnexion fournit les données d'identification et d'état pour tous les circuits du répartiteur. Selon une variante, tous les circuits du répartiteur sont balayés, et l'information d'identification est acquise durant la période requise pour la transmission d'une chaîne binaire de circuit d'interconnexion unique, indépendamment du nombre total de circuits d'interconnexion présents dans le répartiteur.
