Selecting a Test Standard and Cable Type
The test standard and cable type you select determine which standards are used
and which tests are run during cable testing. The test tool is equipped with
information for all the common test standards and cable types.
Several of the test standards for twisted pair cable are defined for both a channel
and a permanent link configuration. The test limits for a channel are looser than
those for a permanent link because the channel limits allow for the effects of two
connections at a horizontal cross-connect and a transition connector near the
telecommunications outlet in the work area. Figures 2-5 and 2-6 earlier in this
chapter show the connections involved in a permanent link and a channel. Chapter
7 further explains these connections.
Note
The test tool displays a message if you try to run a test not supported by the
attached link interface adapter.
