Which tool would you use to verify continuity in phone lines?

A tone and probe kit is used to verify continuity in phone lines because it allows you to send a signal through the wire and identify whether the signal reaches the other end. The tone generator emits a tone that travels along the wire, while the probe detects this tone; if you can hear the tone at the other end, it confirms that there is continuity in the phone line without needing to directly connect to the circuit. This tool is essential for troubleshooting and ensuring that the wiring is intact and functioning properly, which is crucial for maintaining reliable telecommunications.

The other tools listed serve different purposes: a punch down tool is used for connecting wires to punch down blocks; a torque wrench is used for applying a specific torque to bolts and connectors; and a ringing tool is designed to test for voltage rather than continuity in the phone lines. Each of those tools is important for specific tasks but does not provide the same continuity verification capabilities that a tone and probe kit does.
