Abstract: A system and method for electronically identifying connections established through a cross-connect system provides for identification of all hard-wired and temporary patch connections, and any modifications made to same. 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.
