Basic Link and Channel Connections
The cable links you test may or may not include equipment patch cables and extra
transition connections in the telecommunications closet and work area. For
example, cable installers are often responsible only for the permanent cable
installed between the closet and the first wall outlet in the work area. This segment
of cable is the basic link, shown in Figure 7-4. As defined in TSB-67, the basic
link consists of up to 90 m of horizontal cable, one transition connector at each
end, and two test equipment patch cables of no more than 2 m each.
