Which of the following is NOT a tool used in cable termination?

In cable termination, tools play a crucial role in ensuring proper connections and performance of the network. The punch-down tool is explicitly designed for inserting and securing wires into a punch-down block, commonly used in structured cabling systems. The Bix insertion tool is also utilized to insert wires into BIX (Block Internet Exchange) connectors, emphasizing its role in specific types of terminations. The crimping tool is essential for fitting connectors onto the ends of wires, particularly in the creation of Ethernet cables, which further highlights the importance of this tool in the overall termination process.

On the other hand, a test lead is primarily a diagnostic tool rather than a termination tool. It is used for checking continuity, measuring voltage, or testing the electrical characteristics of a cable rather than for physically terminating a cable connection. Its purpose is diagnostic, providing feedback on a cable's ability to carry signals once it has already been terminated, which is why it is not categorized as a tool used in cable termination.
