B Troubleshooting
Intermittent VDSL LED(s)
A VDSL LED turns on and off intermittently.
Table 23-2 Troubleshooting a Non-Constant VDSL LED
STEPS CORRECTIVE ACTION
1 Disconnect the phone wire coming from the USER port of the VES and connect the VDSL modem or
router directly to the USER port of the VES using a different telephone wire.
If the VDSL LED stays on, check for a problem with the building’s phone wire.
2 Use the VDSL CI commands to reset and reconnect the VDSL channel.
Data Rate
The SYNC-rate is not the same as the configured rate.
Table 23-3 Troubleshooting the SYNC-rate
STEPS CORRECTIVE ACTION
1 Disconnect the phone wire coming from the USER port of the VES and connect the VDSL modem or
router directly to the USER port of the VES using a different telephone wire.
If the rates match, the regular phone wire quality may be limiting the speed.
2 Do a local and remote feedback test from menu 24.4 to determine if there are problems with the
telephone line.
Configured Settings
The VES’s configured settings do not take effect at restart.
Table 23-4 Troubleshooting the VES’s Configured Settings
CORRECTIVE ACTION
All VDSL parameters and flags set using VDSL C/I commands are effective at run-time only. If you restart the
VES, you will lose the configuration changes you made with CI commands. To save changes permanently, use the
appropriate web configurator screen(s).
If this does not work, contact the distributor.
Password
I forgot the password to my VES.
Table 23-5 Troubleshooting the Password
STEPS CORRECTIVE ACTION
1 Upload the default configuration file. All settings will return to the default value and previously saved
configurations will be lost.
2 Send a screen shot of your VES’s MAC address to your local distributor.
