The computer behind a DSL modem or router cannot access a local server
connected to the SAM1316-22.
Table 113 DSL Data Transmission Troubleshooting
STEPS CORRECTIVE ACTION
1 Check the switch mode and port isolation settings.
Check to see that the VPI/VCI and multiplexing mode (LLC/VC) settings in the
subscriber’s DSL modem or router match those of the DSL port.
If the subscriber is having problems with a video or other high-bandwidth
services, make sure the SAM1316-22’s DSL port’s data rates are set high
enough.
2 Check the VLAN configuration.
3 Ping the SAM1316-22 from the computer behind the DSL modem or router.
4 If you cannot ping, connect a DSL modem to a DSL port (that is known to
work).
If the DSL modem or router works with a different DSL port, there may be a
problem with the original port. Contact the distributor.
5 If using a different port does not work, try a different DSL modem or router
with the original port.
Table 114 Troubleshooting a Local Server
STEPS CORRECTIVE ACTION
1 See Section 62.5 on page 437 to make sure that the subscriber is able to
transmit to the SAM1316-22.
2 Make sure the computer behind the DSL device has the correct gateway IP
address configured.
3 Check the VLAN configuration (see Chapter 17 on page 133 ).
4 Check the cable and connections between the SAM1316-22 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.
