FAQs

Q: When testing, should I do a permanent link test or a channel test?

A: Permanent link is a more reliable test. It tests all the static components of a communication circuits. Typically it consists of a jack, horizontal cable and a patch panel port. It could also include a consolidation point along the link. Channel testing includes the testing of the patch cords at each end. This test is not as reliable since patch cords are often relocated/replaced. Also, due to the nature of construction, it is unlikely that the patch cords will be in place when testing is required to be done nor is it likely that the patch cords, if used, will remain plugged in post testing, unless the building is already occupied and the cabling was installed as a result of an upgrade.
