VES-1000 Series Ethernet Switch
15-2 Troubleshooting
15.3 Intermittent VDSL LED(s)
A VDSL LED turns on and off intermittently.
Table 15-C Troubleshooting a Non-Constant VDSL LED
STEPS CORRECTIVE ACTION
1 Disconnect the phone wire coming from the USER port of the VES-1000 Series switch and connect the
VDSL modem or router directly to the USER port of the VES-1000 Series switch 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 (see Chapter 12 ).
15.4 Data Rate
The SYNC-rate is not the same as the configured rate.
Table 15-D Troubleshooting the SYNC-rate
STEPS CORRECTIVE ACTION
1 Disconnect the phone wire coming from the USER port of the VES-1000 Series switch and connect the
VDSL modem or router directly to the USER port of the VES-1000 Series switch using a different telephone
wire.
If the rates match, the regular phone wire quality may be limiting the speed (see section 5.1).
2 Do a local and remote feedback test from menu 24.4 (see section 9.5) to determine if there are problems
with the telephone line.
15.5 Configured Settings
The VES-1000 Series switch’s configured settings do not take effect at restart.
Table 15-E Troubleshooting the VES-1000 Series switch’s Configured Settings
CORRECTIVE ACTION
After you finish configuring the settings using the SMT, remember to press [ENTER] at the prompt “Press
ENTER to Confirm…” to save your configuration.
All VDSL parameters and flags set using VDSL C/I commands are effective at run-time only. If you restart
the VES-1000 Series switch, you will lose the configuration changes you made with CI commands. To save
changes permanently, please use the appropriate SMT menu.
If this does not work, contact the distributor.
