Abstract

An improved method and apparatus for identifying individual wires that are connected between a network patch panel and a remote wall jacks is provided. A permanent LED lamp is installed adjacent to each jack in a computer network patch panel that is electrically connected to two terminals of each of the patch jacks. A handset component that produces direct current voltage is plugged into a remote wall jack to be tested, an electrical circuit is completed using the permanent network cabling thereby energizing the LED indicator lamp at the patch panel, providing positive visual confirmation of the patch panel location that corresponds to the wall jack location. The method of the present invention provides for one worker to remain at the patch panel location, as a second worker, using the handset component of the present invention, plugs the device into a wall plug in a remote location, which lights the corresponding LED on the patch panel. The worker at the patch panel communicates the circuit that was illuminated to the worker at the remote location. Thus, the correct wire for that location on the patch panel is instantly identified, and can be labeled by the remote worker.

Claims

1. An apparatus for identifying at least one cable in a cabling system, said cable having a first end and a second end remote from said first end, said cable containing at least a first and second conductive wire, said apparatus comprising:

a patch panel having at least one patch jack, said patch jack in electrical communication with said at least first and second conductive wires in said first end of said cable;

at least one indicator lamp, permanently installed in said patch panel adjacent to said patch jack, said indicator lamp having a first electrical lead in electrical communication with said first conductive wire and a second electrical lead in electrical communication with said second conductive wire;

at least one wall jack in electrical communication with said at least first and second conductive wires in said second end of said at least one cable; and

means for applying a test voltage to said at least one wall jack,

whereby the applied test voltage at said at least one wall jack causes said indicator lamp adjacent to said patch jack to light, when the patch jack is electrically connected to the wall jack through said first and second conductive wires of said cable.

2. The apparatus of claim 1, wherein said lamp is a light-emitting diode.

3. The apparatus of claim 1, wherein said at least one patch jack further comprises a predetermined number of individual patch jacks and said at least one indicator lamp comprises a predetermined number of individual indicator lamps corresponding to said predetermined number of individual patch jacks,

wherein said at least one wall jack comprises a predetermined number of individual wall jacks corresponding to said predetermined number of individual patch jacks,

said individual wall jacks being located remotely from said patch jacks and being in respective corresponding electrical communication with said individual patch jacks.

4. The apparatus of claim 1, wherein said means for applying a test voltage includes a test plug for insertion into said at least one wall jack, and a source of DC voltage electrically connected to said test plug.

5. The apparatus of claim 4, wherein said source of DC voltage is a battery.

6. The apparatus of claim 4, wherein said means for applying a test voltage further includes a current-limiting resistor electrically connected between said source of DC voltage and said test plug.

7. A method of identifying cables in a cabling system, each of said cables having wire pairs, said method comprising the steps of:

a. providing a patch panel having permanently installed indicator lamps in electrical communication with said wiring pairs;

b. providing jack locations remote from said patch panel;

c. providing a means for sequentially applying a test voltage at each remote jack location to said wire pairs connected to said patch panel;

d. applying said test voltage to each remote jack, one remote jack at a time, the remote jack being connected to one of a plurality of wire pairs connected to the patch panel, whereby said applied test voltage at the remote jack causes said indicator lamp at said patch panel jack to light, when the particular patch panel jack is electrically connected to the remote jack through a wire pair;

e. recording at the patch panel jack location which indicator lamp lights when the test voltage is applied to a particular remote jack, so as to identify the patch panel jack and the remote jack by associating them with one another;

f. communicating the fact of a successful identification to a worker at the remote location;

g. choosing a new remote jack to test; and

h. repeating steps “

d”

through “

g”

above until all wire pairs desired to be tested have been identified.

8. The method of claim 7, wherein said indicator lamp is a light-emitting diode.

9. The method of claim 7, wherein said means for applying a test voltage further includes a test plug for insertion into said remote wall jack and a source of DC voltage electrically connected to said test plug.

10. The method of claim 8, wherein said source of DC voltage is a battery.

11. The method of claim 9, wherein said means for applying a test voltage further includes a current-limiting resistor electrically connected between said source of DC voltage and said test plug.

12. An cable termination device for use in a cabling system, said cable having a first end and a second end remote from said first end, said cable containing at least a first and second conductive wire, said device comprising:

a patch panel having at least one patch jack, said patch jack in electrical communication with said at least first and second conductive wires in said first end of said cable; and

at least one indicator lamp, permanently installed in said patch panel adjacent to said patch jack, said indicator lamp having a first electrical lead in electrical communication with said first conductive wire and a second electrical lead in electrical communication with said second conductive wire.
