Tele-Communication (Telecom) Terms Glossary and Dictionary
Patch panel is a panel of network ports contained together, usually within a telecommunications closet, that connects incoming and outgoing lines of a LAN or other communication, electronic or electrical system. The patch panel allows easy access to all cable and ground line conductors. Conductor functions can be interchanged or checked rapidly for continuity, insulation, or quality of signal brought to the surface. Also, it provides easy access to output of surface panels.
