Which term describes the process of terminating copper cables into a jack using insulation displacement?

• A. Punchdown
• B. Crimping
• C. Butt set
• D. Splicing

Answer: (A)

Punchdown is the method used to terminate copper conductors into a jack or distribution block when insulation-displacement contacts are used. A punch-down tool pushes each conductor into a slot on the jack or block; the metal contact pierces the insulation and makes a solid connection with the copper. This approach is common for keystone jacks and 110/66 blocks in Ethernet and phone cabling. Crimping, by contrast, attaches a connector to the wire using a crimp tool and is not insulation-displacement into a jack, while splicing joins wires together rather than terminating them into a jack, and a butt set is a testing device rather than a termination method.
