Definition of Basic Link and Channel

Basic Link

The "Basic Link" configuration is intended for use by cable installers and contractors, testing the fixed wiring in a building. A Basic Link may consist of up to 90 meters of horizontal cable, only one transition connector on each end of the horizontal cable, and two Test Equipment Cords with a length of no more than 2 meters each.

Channel

A "Channel" configuration is intended for LAN owners and LAN systems designers to test the end-to-end connections of their LAN cabling. A Channel may consist of up to 90 meters of horizontal cable, one or two transition connectors on each end of the horizontal cable, and up to 10 meters of user patch cables for a total maximum length of 100 meters. The user's patch cables are used to make the connection to the networking hardware, such as the HUB to Patch Panel and Workstation to Wall Outlet connections.
