Chapter 5: Troubleshooting the Premises Wiring Identifying Ethernet wiring issues Many homes are now pre-wired with twisted pair wiring suitable for Ethernet data services. The EIA/TIA 568A standard offers two accepted color code standards,T-568A and T-568B.The actual wiring and connectivity is exactly the same. Both work equally well but they should not be mixed in the same install. Notice the difference in Figure 5.4. A-Standard uses orange for line 2 and green for line 3 while B-Standard uses green for line 2 and orange for line 3. T-568A Standard 1 2 3 4 5 6 7 8 3 2 Figure 5.4 T-568A and T-568B standards. Verification of proper termination is very important. Between 75% and 85% of the time in-home technicians spend troubleshooting can be attributed to efforts to resolve improper terminations. The most common termination faults can be found by a wiring verifier. Continuity tests include verification of pin-to-pin connections and the ability of the wire to carry a signal. The verification tester also tests for shields and voltage on line. This is a basic connectivity test, not a stress test.
