  • Wire maps can be very helpful in troubleshooting cabling problems with UTP cable. A wire map allows the network technician to verify which pins on one end of the cable are connected to which pins on the other end. Prior to starting the lab, the teacher or lab assistant should have several correctly wired CAT 5 cables to test. The cables should be both straight-through and crossover. There should also be several CAT 5 cables created with problems such as poor connections and split pairs to test. Cables should be numbered to simplify the testing process and to maintain consistency.
