3.4 Data Rate

The SYNC-rate is not the same as the configured rate.
3.5 Management and Configuration
V
The line card is not manageable.
The line card always uses the default configuration. Any changes you made to the line card are
stored on the MSC. By default, the MSC is allowed to manage every line card. Use the
lcman
show command on the MSC to see a line card’s connection status. If you still cannot manage
the line card from the MSC, the line card’s configuration file may be damaged or the firmware
may be old, you may need to restore the default configuration file or upload new firmware
using the line card’s console port.
Table 12 Local Server Troubleshooting
STEPS CORRECTIVE ACTION
1 Refer to Section 3.2 on page 30 to make sure that the subscriber is able to transmit to the
line card.
2 Make sure the computer behind the DSL device has the correct gateway IP address
configured.
3 Check the VLAN configuration (refer to the MSC User’s Guide).
4 Check the cable and connections between the line card and the local server.
5 Try to access another local server.
If data can be transmitted to a different local server, the local server that could not be
accessed may have a problem.
Table 13 SYNC-rate Troubleshooting
STEPS CORRECTIVE ACTION
1 Connect the DSL modem or router directly to the DSL port using a different telephone wire.
2 If the rates match, the quality of the telephone wiring that connects the subscriber to the
DSL port may be limiting the speed to a certain rate.
If they do not match when a good wire is used, contact the distributor.
