5 If you cannot ping, connect a DSL modem to a DSL port (that is known to work) on the same line
card.
If the DSL modem or router works with a different DSL port, there may be a problem with the original
port. Contact the distributor.
7 If using a different port does not work, try a different DSL modem or router with the original port.

A DSL LED turns on and off intermittently.
Table 14-3 Troubleshooting a Non-Constant DSL LED
STEPS CORRECTIVE ACTION
1
Use the
linerate
command to check the subscriber’s telephone wiring (refer to the chapter on
ADSL commands for details).
2 Connect a DSL modem directly to the DSL port of the line card using a different telephone wire.
If the DSL LED still turns on and off repeatedly, contact the distributor.
14.4 Data Rate
The SYNC-rate is not the same as the configured rate.
Table 14-4 Troubleshooting the SYNC-rate
STEPS CORRECTIVE ACTION
1 Connect the DSL modem or router directly to the DSL port of the line card using a different
telephone wire.
2 If the rates match, the quality of the telephone wiring that connects the subscriber to the line card
may be limiting the speed to a certain rate. Use the
linerate
command to check the subscriber’s
telephone wiring.
If they do not match when a good wire is used, contact the distributor.
14.5 Configured Settings
The line card’s configured settings do not take effect at restart.
Table 14-5 Troubleshooting the Line card’s Configured Settings
CORRECTIVE ACTION
Use the
config save
command after you finish configuring to save your settings to the line card. If this
does not work, contact the distributor.
