4.13.1 Cable Diagnostics
The Cable Diagnostics performs 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 follows:
 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 causes the link to drop while the
diagnostics is running.
After the diagnostics is finished, the link is reestablished. And the following functions are available:
 Coupling between cable pairs.
 Cable pair termination
 Cable length
Cable Diagnostics is only accurate for cables of length from 15 to 100 meters.
