4.14.6Cable Diagnostics

The Cable Diagnostics page contains fields for performing tests on copper cables. These functions have the ability to identify the cable length and operating conditions, and to isolate a variety of common faults that can occur on the Cat5 twisted-pair cabling. There might be two statuses as follow:

„If the link is established on the twisted-pair interface in 1000BASE-T mode, the Cable Diagnostics can run without disruption of the link or of any data transfer.

„If the link is established in 100BASE-TX or 10BASE-T, the Cable Diagnostics cause the link to drop while the diagnostics are running.

After the diagnostics are finished, the link is reestablished. And the following functions are available.

•Coupling between cable pairs.

•Cable pair termination

•Cable Length

Anomalous coupling between cable pairs can be caused by shorted wires, improper termination, or high crosstalk resulting from an incorrect wire map. These conditions can all prevent the PLANET switch from establishing a link. The screen in Figure 4-61 appears.
