Abstract: A system for use in locating and testing a cable having a first end connected to a first connector and a second end connected to a second connector where the second connector is one of a plurality of connectors within a patch panel. The system includes a first device having a first cable certification and test circuitry which is couplable to the first connector and a second device having a second cable certification and test circuitry which is couplable to the second connector. One of the first device and the second device further includes circuitry for generating a tone signal that is to be applied to the cable and the other one of the first device and the second device further includes a probe for receiving the tone signal and for generating an output indicative of a strength of the received tone signal.

Abstract: A system for use in testing a local area network (LAN) cabling system having a LAN cable communicatively coupled to a pair of sockets. The system includes a first LAN testing device that is adapted to exchange test communication signals with a second LAN testing device through the LAN cabling system and a cable communicatively coupled to the first LAN testing device having a plug sized and arranged to communicatively couple with a one of the pair of sockets. The plug includes a switch device and an indicator device that are communicatively coupled to the first LAN testing device via the cable.
