A tone generator is used to place a tone on a cable that can be received by which device at the other end?

A tone generator is a device used in telecommunications to send a signaling tone through a cable, making it easier to trace or identify the cabling pathway. An amplified probe is specifically designed to pick up these tones from the cable.

When the tone generator emits a sound, the amplified probe can detect and amplify that signal, providing a clear indication of the tone's presence and helping technicians locate the cable's endpoint or any breaks in the line. This is essential for diagnosing cable faults and verifying connections.

In contrast, other devices such as butt sets, frequency counters, and TDRs (Time Domain Reflectometers) serve different functions. A butt set is primarily used for placing calls on a phone line and does not specialize in tone detection. A frequency counter measures frequencies and is not designed to pick up audio tones from a cable. A TDR is useful for measuring cable lengths and detecting faults by reflecting signals, but it does not directly interpret the tone generated by a tone generator. Therefore, the amplified probe is the correct device to receive the tone placed on a cable by a tone generator.
