A network technician needs to install patch cords from the UTP patch panel to the access switch for a newly occupied set of offices. The patch panel…

A toner, which consists of a tone generator and an inductive probe, is the most efficient tool for this task. The tone generator is connected to the network jack in the office, sending an electrical signal through the U-T-P cable. The technician then uses the probe at the patch panel. By sweeping the probe across the ports, it will emit an audible tone when it detects the signal from the generator, thus quickly and easily identifying the correct port without needing to physically plug into each one. This process is known as "toning out" a cable and is the standard industry practice for tracing unlabeled wires.

B. Laptop: Using a laptop is inefficient. It would require connecting a patch cord from the switch to each panel port sequentially until the laptop shows a network link.

C. Cable tester: A basic cable tester requires plugging its remote unit into the wall jack and the main unit into each patch panel port one by one, which is slower than a toner.

D. Visual fault locator: This tool is used exclusively for locating breaks and identifying ends of fiber optic cables by transmitting a visible red light; it is incompatible with copper UTP cabling.

In Chapter 2

"Networking Tools

" the text describes the function of a tone generator and probe: "To trace a wire

you connect the tone generator to the wire at one end... Then you use the probe at the other end... to find the same wire by listening for the tone. This process is called toning a wire." This directly supports its use for identifying a specific cable in a bundle or at a patch panel.

In the section describing standard tools for network technicians

the documentation explains that a "Tone and Probe Kit" is used to "identify a specific wire pair or conductor within a bundle

at a cross-connect point

or at a remote end." This aligns perfectly with the scenario of identifying an unlabeled port on a patch panel. (Reference: UW IT Connect

Tools section for network cabling).

Section 1.05

"Quality Assurance

" subsection A.3

specifies required test equipment for cable installers

which includes a "wire mapping tester with tone generation." This indicates that tone generation is a standard

required method for identifying and verifying cable runs in a professional installation environment.
