Method and apparatus for tracing remote ends of networking cables
First Claim
1. An indicator circuit for signaling a cable connection between two computer-related devices joined by a networking cable comprising a plurality of twisted copper wire pairs encased in a flexable sheath comprising:
- an electrically activated switch for energizing an electrically activated telltale when energy is applied to the circuit, wherein the electrically activated switch comprises at least one of a field effect transistor, a switching relay, a programmable gate array, a programmable digital computer, or a transistor that performs a switching function when the voltage is greater than a preselected level; and
an electrically activated telltale for visually indicating the cable connection.

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 apparatus 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.
