What does a ringing tool do in cable installation?

A ringing tool is specifically designed for stripping the outer jacket from network cables, including CAT3 and CAT5 wires. This tool allows the installer to remove the insulation without damaging the inner conductors. Properly stripping the cable is crucial in ensuring that connections are secure and reliable, as it prepares the cable for termination with connectors or patch panels. This process is an essential step in cable installation because it directly impacts the performance and integrity of the network.

The other options pertain to functions that do not align with the primary purpose of a ringing tool. For instance, installing security devices involves different installation practices, marking spots for connections refers to identifying locations for termination, and testing network connectivity involves using different tools designed to assess whether a network connection is active and functioning properly. Each of these tasks requires specific tools and techniques distinct from the capabilities of a ringing tool.
