Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0008] For a better understanding of the invention hereinafter claimed, reference may be had to a preferred embodiment shown in the following drawings in which:

[0009] FIG. 1 illustrates a prior art system and method for using a tone and probe system to trace network and communications cables;

[0010] FIG. 2 illustrates a prior art system and method for using LAN testers to test a traced network or communications cable; and

[0011] FIG. 3 illustrates the subject, improved system and method for tracing and testing network and communication cables.

DETAILED DESCRIPTION

[0012] With reference to the figures, an improved system and method for tracing and testing network and communication cables is now described.

[0013] Turning now to FIG. 3, it is to be appreciated that the described system and method is intended to assist an operator, who is connecting some specific test equipment (e.g. a network cable certifier) to the two ends of a cable to be tested, in further identifying the exact connectors to be used. While it continues to be necessary to identify the specific connector, e.g., socket, that terminates the cable to be tested on a panel of many connectors, rather than moving a dedicated probe across the front of these sockets, as described above in connection with prior art FIG. 1, and then replacing the tone generator at the one end of the cable with the first part of the network cable certifier equipment and then plugging in the cable to the second part of the network cable certifier, as described above in connection with prior art FIG. 2, the following proposes a system in which a tone generator is incorporated into a network cable certifier so both the tone generator and network cable certifier are connected at the same time. To this end, as further shown in FIG. 3, the connector 10 on the end of an intermediate cable 15 that is coupled to the tone generator/network cable certifier is coupled with an end of an installed cable 17, which end terminates at a connector 16. The other end of the intermediate cable 17 is typically fitted into a patch panel containing many termination connectors 19, one of which provides the termination for the cable 17. Thus, a connector 11 on the end of an intermediate cable 21 that is coupled to a network cable certifier, which also has associated therewith probe circuitry, may be placed into communication with the termination connectors 19 of the patch panel to thereby allow the cable 17 to be traced.

[0014] More particularly, once the connector 10 on the end of an intermediate cable 15 is coupled to the connector 16 as described above, the circuitry inside the right hand (as shown in FIG. 3) network cable certifier will be capable of receiving a signal (if any) from a connector 19 (where the signal is generated by the left hand tone generator/network cable certifier coupled to the cable 11) whereupon the received signal will be processed in a similar way to a normal probe as described above. For tracing the cable, an operator is intended to move the connector 11 into at least close proximity to each of the connectors 19, e.g., sockets, on the patch panel, in turn, whereupon the right hand network cable certifier will be able to indicate the received signal strength (of the connector 19 currently under test) audibly, mechanically (e.g., via vibration), and/or visibly to the operator including, possibly, by have one of these indicators attached to or combined into the connector 11. In this manner, the connector 19 exhibiting the highest received signal strength will be the one connected to the left hand network cable certifier at the other end of the cable, so both ends of the cable 17 to be tested have been identified. It is now only necessary to directly couple the connector 11 with the appropriate connector 19, e.g., insert the connector 11 into the socket at which the traced cable terminates, and testing of the installed cable can begin using the same equipment.

[0015] As will be appreciated from the foregoing, a key advantage of this described design is that it simplifies and speeds up the identification of a specific connector located with many others and so allows testing to begin more quickly.

[0016] It will also be appreciated that detailed discussion of the actual implementation of each module is not necessary for an enabling understanding of the invention. The actual implementation is well within the routine skill of a programmer and system engineer, given the disclosure herein of the system attributes, functionality, and inter-relationship of the various functional modules in the system. A person skilled in the art, applying ordinary skill can practice the present invention without undue experimentation.

[0017] While various concepts have been described in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those concepts could be developed in light of the overall teachings of the disclosure. For example, the same procedure may be performed in the reverse direction, so that the remote network cable certifier is the tone generator and the display end network cable certifier cable connector is used as a probe. In addition, the probe circuitry and/or the devices for providing an indication of received signal strength can be incorporated into the socket connector of the intermediate cable that is to be coupled to the cable certifier. As such, the particular concepts disclosed are meant to be illustrative only and not limiting as to the scope of the invention which is to be given the full breadth of the appended claims and any equivalents thereof.
