Abstract: For tracing multi-conductor cable runs from multiple phone/data locations throughout a building or complex to a junction facility where the cables need to be systematically identified and connected to a terminal panel, rapid tracing and identification are accomplished by deploying a large number of special low-cost senders, e.g. a set of forty eight senders, connecting as many senders as required to energize every cable at each location via its standard modular jack. Each sender delivers a unique identification signal, e.g. a spoken number from 1 to 48, energizing a corresponding phone cable and/or data cable. With all of the cables thusly energized simultaneously and distinguishably, a technician working with a proximity probe in the junction facility can rapidly identify and tag and/or connect all the cables in an uninterrupted session, without requiring the usual assistant and intercom link, and with no time wasted probing unenergized cables.
