Tone generators and probes
A tone generator ("toner") is like a radio transmiter. You attach its alligator clips to a pair of wires, or plug its plug into a phone or data jack, and it sends a sound through the wire.
The probe works like a radio receiver. It picks up the tone when it is near a wire, even if it is one wire in the middle of a bundle of wires, or is inside a wall. An internal speaker lets you hear the sound that the probe picks up, and you can also attach a buttset to hear better in noisy environments, or when the signal is weak.
A tone generator and probe are extremely useful in identifying wires, finding open circuits and short circuits, diagnosing crosstalk, and other telecom tasks. They're also good for tracing speaker wires and alarm and remote control circuits.
Most tone generators also allow you to test polarity of a phone line, indicate the presence of voltage, test continuity, and provide "talk battery" to test phone equipment when no dialtone is available.
