Method and apparatus for tracking remote ends of networking cables
First Claim
1. A networking cable for transmitting nominal signals, the networking cable comprising:
- a plurality of twisted copper wire pairs;
at least one electrically activated indicator affixed to at least one end of at least one pair of said plurality of twisted copper wire pairs for providing an indication in response to an illumination signal; and
a driver for generating an illumination signal whenever signals other than said nominal signals are applied to said at least one pair of said plurality of twisted copper wire pairs, said driver configured so as to not interfere with the flow of data through the cable, said driver and said indicator coupled to at least one of said twisted copper wire pairs.

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. The networking cable also may be used for convenient telephonic communication by service personnel. One embodiment includes the cable as described above except with one end having a connector mateable with a standard Category 5 networking cable thereby providing for a standard networking cable to be converted into a specialized networking cable usable for tracing cable ends.
