Tone Generators (and Tone Locators)
A tone generator is a device that can save a network installer many hours of frustration. Strangely, the tone generator has a partner that goes wherever it goes but is seldom mentioned: the tone locator. You might hear the tone generator and the tone locator referred to as the fox and hound.
As you might expect, the purpose of the tone generator is to generate a signal that is transmitted on the wire you are attempting to locate. At the other end, you press the tone locator against individual wires. When it makes contact with the wire that has the signal on it, the locator emits an audible signal or tone.
The tone locator is a useful device, but it does have some drawbacks. First, it often takes two people to operateone at each end of the cable. Of course, one person could just keep running back and forth; but if the cable is run over great distances, this could be a problem. Second, using the tone generator is a time-consuming process because it must be attached to each cable independently.
