Abstract: A method and a circuit is disclosed that facilitates identifying a remote end and optionally an intermediate location of an installed cable, such as a cable for carrying data, without the need to disconnect the cable. One or more circuits may be connected across two wires along the length of a cable. Each circuit includes a power connector, a switching circuit and an indicator, such as a light emitting diode (LED), connected across the two wires included in a cable. The circuit is configured such that the indicator in each circuit connected to the two wires is illuminated in responsive to a nominal DC voltage applied to the power connector in any circuits connected across the two wires without disrupting any data being carried thereby. In one embodiment of the invention, the circuit is directly into a cable connector. In an alternate embodiment of the invention, the circuit is configured to be retrofit in the field for use with existing cables.

Abstract: This specialized networking cable includes a plurality of twisted copper wire pairs encased in a flexible sheath for effectuating transmissive interconnections, electrically activated telltales affixed to both ends of the cable at positions adjacent to and connected to at least one of the copper wire pairs for providing an identification signal when activated; and means for selectively applying a current to the cable that activates the telltales and does not interfere with the flow of data through the cable whereby the telltales may be activated on at least one of the twisted copper pairs. An LED and an electric power connector suitable for plug-in connection of a power pack are affixed to the cable adjacent each end such that both LEDs are lighted whenever power is applied to either of the electrical connectors. The attendant illumination of the LEDs readily indicates where both ends of the networking cable are located.
