3.9.4.4 Testing
Every effort should be made to ensure a quality installation of the computer
network cabling system. Even the best installation effort cannot guarantee a
properly working system. It is therefore required that a computer network cabling
system be tested for proper performance.

The procedures and specifications in the TIA/EIA Telecommunications System
Bulletin (TSB) 67 shall be used for this testing. TSB 67 has four primary
parameters to test. Below is an overview of the four test parameters needed to
assure a properly working system.

Wire map
The wire map test is used to verify wire pair to pin termination at each end of the
cable and to check for installation connectivity errors. It is recommended that
100% of cables be tested using a testing tool such as Microtest® Microscanner™
Pro. (Be sure the tester can check for a “split pair” configuration).
