Troubleshooting
This chapter covers potential problems and possible remedies. After each problem description, some steps are
provided to help you to diagnose and to solve the problem.
15.1 SHDSL or ADSL LED(s)
An SHDSL or ADSL LED is not on.
Table 15-1 Troubleshooting the DSL LED(s)
STEPS CORRECTIVE ACTION
1 Connect the DSL modem or router directly to the DSL port of the network module using a
different telephone wire.
If the LED turns on, check for a problem with the building’s phone wire.
2 Make sure the DSL port is enabled (refer to the sections on enabling SHDSL ports and
enabling ADSL ports).
3 If the LED remains off, contact the distributor.
15.2 Data Transmission
The SHDSL or ADSL LED is on, but data can not be transmitted.
Table 15-2 Troubleshooting Data Transmission
STEPS CORRECTIVE ACTION
1 Connect the DSL modem or router directly to the DSL port of the network module 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 the VPI/VCI settings in the user’s DSL modem or router match those in the
network module (refer to sections 3.5 and 3.6). Also make sure that it is using RFC 1483
encapsulation, bridge mode and LLC- based multiplexing.
3 Make sure that the device type of the network module’s IP address is set to bridge (refer to
section 11.2).
4 Check the VLAN configuration of the network module (refer to Chapter 8 ).
5 Ping the network module from the user’s computer.
6 If you cannot ping, connect the DSL modem or router to another network module DSL port.
If the DSL modem or router works with a different port, then there may be a problem with the
port user’s 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.
