Overview
In Ethernet networking, a punchdown refers to the process of connecting individual wires from a twisted-pair cable into a patch panel, keystone jack, or other termination point using a punchdown tool. This method is essential for structured cabling systems in both residential and commercial environments, ensuring reliable and organized network connections.
Key Features
-
Punchdown Tool
