What is the function of a tone generator in network troubleshooting?

To analyze packet loss
To create an audible signal on a wire
To capture network traffic
To test cable frequency

The correct answer is: To create an audible signal on a wire

A tone generator is a tool specifically designed to assist in network troubleshooting by creating an audible signal that can be sent along a cable. This signal helps technicians trace and identify the specific wire or cable path in a network setup. When the tone is applied to a wire, it emits a sound that can be detected by a tone probe, allowing the technician to follow the cable's route or locate breaks and faults within the wiring. This is particularly useful in environments where multiple cables may be bundled together, making it difficult to identify which cable is which without a straightforward method for tracing them. The audible signal aids in easy identification without the need to visually trace every wire, thereby saving time and increasing efficiency in troubleshooting scenarios.
