Which testing tool is known for identifying a specific cable pair using toning?

The tool recognized for identifying a specific cable pair through toning is the inductive amplifier. Toning involves sending a tone signal through a particular wire or cable pair, allowing a technician to trace and identify it among other wires. Essentially, the inductive amplifier works by picking up this tone signal when coupled with a compatible tone generator. This makes it a valuable tool for technicians who need to pinpoint or verify the routing of specific cable pairs in a larger cabling environment.

Other options, while useful in their own right, serve different purposes. Wire map testers are primarily designed to check the integrity and configuration of cables by ensuring correct connections but do not specifically utilize toning for identifying pairs. Certification test sets are comprehensive tools utilized to measure and certify the performance of cabling installations against established standards but do not focus on the toning function. Visual verifiers, on the other hand, allow technicians to see the status of the connections visually, typically using light signals, but do not involve the identification process that toning offers. Thus, the inductive amplifier stands out as the specialized tool for identifying cable pairs using toning.
