>> The Technology Introduction

A tone and probe set is a tool with two separate pieces: the tone generator and the probe that helps you to listen for the tone. It is also the simplest type of copper cable tester. Telecom technicians sometimes also call this test set a \”fox and hound\” wire tracer.

This type of device consists of one unit called the \”tone generator\”. You connect the tone generator to one end of a cable with a standard jack, or to an individual wire with alligator clips. This unit then injects an audible tone signal down the lenght of the cable.

The other unit is a penlike probe that emits an audible tone when touched to the other end of the cable or wire or even to its insulating sheath. Here is how you use it: Hold the probe against many cables until the one that has the tone generator connected to it has been identified with a continuous audible beep.

A tone and probe set is most commonly used by telephone cable engineers who need to identify a particular pair of telephone (copper) wires. For example, some installers prefer to run all of the cables for a network to the central punchdown block without labeling them and then to use a tone generator to identify which block is conncted to which wall plate and label the punchdown block accordingly.

You can also use the tone generator and probe set to identify a particular cable at any point between the two ends. Because the probe can detect the cable containing the tone signal through its sheath, it can help you to locate one specific cable out of a bundle in a ceiling conduit or other type of raceway. You just need to connect the tone generator to one end and touch the probe to each cable in the bundle until you hear the tone.

In addition, by testing the continuity of individual wires using alligator clips, you can use a tone generator and probe to locate opens, shorts, and miswires.

An open wire will not produce a tone at the other end, a short will produce a tone on two or more wires at the other end, and an improperly connected wire will produce a tone on the wrong pin at the other end.

>> Most Common Product Features

The compact tone generator offers several easy-to-use capabilities to conduct line tracings and ensure proper signal path quality for data and voice installation.

Here are some of the common features you may find on a more advanced tone generator and probe set.

1. Several distintly different tones for multiple line testing selected from front panel.

2. Auto-off and no power draw in continuity mode for extended battery life

3. Tone may be added in any mode – phone sets without a monitor feature can pick up tone

4. Separate talk battery mode for increased voltage and to power a dry line for talking

5. Modlar jack allows use of modular cable or molded-in alligator clip leads or molded-in angled bed-of-nails leads

6. Can be used with wearable headsets or a standard cell phone headset

>> Disadvantages of Tone Generator and Probe Testing

However, the tone generator testing process is extremely time-consuming and it\’s nearly as prone to errors as the calbe installation itself.

You either have to continually travel from one end of the cable to the other to move the tone generator unit or use a partner to test each connection, keeping in close contact using radios or some other means of communication in order to avoid confusion.

When you consider the time and effort involved, you will probably find that investing in a wire map tester is a more practical solution.
