Troubleshooting
This chapter covers potential problems and possible remedies. After each problem description, some
steps are provided to help you diagnose and solve the problem. Refer to the Troubleshooting chapter in
the Hardware Installation Guide for more troubleshooting information.
26.1 VDSL LED(s)
A VDSL LED is not on.
Table 26-1 Troubleshooting the VDSL LED(s)
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 LED turns on, check for a problem with the building’s phone wire.
2 Set the VDSL modem to “auto-negotiate”. If this is not possible, set it to 100 Mbps, half duplex mode.
3 Use the VDSL CI commands to reset and reconnect the VDSL channel (see Chapter 23 ).
4 If the LED remains off, contact the distributor.
26.2 Data Transmission
The VDSL LED is on, but data cannot be transmitted.
Table 26-2 Troubleshooting Data Transmission
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 data can be transmitted, check for a problem with the building’s phone wire.
2 Check to see that you are using the correct VDSL mode.
3 Check the VLAN configuration of the VES.
4 Do a local and remote feedback test from menu 24.4.
5 Ping the VES from the user’s computer.
6 If you cannot ping, connect the VDSL modem or router to another VES VDSL port.
If the VDSL modem or router works with a different port, then there may be a problem with the original
port. Contact the distributor.
7 If using a different port does not work, try a different VDSL modem or router with the original port.
