Chapter 6: Operation

LAN Performance Verification Level 2 displays the LAN Performance Verified Level 2 speed capability of the cable. The display is the result of the data gathered during Level 1 testing (simulated data) and Level 2 testing (real data) into a graph that “LAN Performance Verifies” the speed capability of the cable.

Additional notes: The Level 2 testing adds real live data with the connection of a real live data source (a hub, switch, or PC) to the far end of the cable. This adds an important test element: signal attenuation of live data. Adding this to the test data gathered during Level 1 testing creates Level 2 testing. The end result of LAN Performance Verification Level 2 is the speed graph shown above. It verifies the measured data speed capability of the cable in Figure 6-31. Use Level 2 verification whenever you want to test a cable with real live data. With the Level 2 testing, you are LAN Performance Verifying both your cable and your network port at the same time (you can test your cable with the exact port that it will use in the network).
