PROBLEM CORRECTIVE ACTION
The VDSL LED is
off.
Check the telephone wire and connections between the Prestige DSL port and the
wall jack.
Make sure that the telephone company has checked your phone line and set it up
for DSL service.
Make sure the distance from the Prestige to the DSLAM does not exceed 1.25 km
(3750 feet). Rates deteriorate the further away the DSLAM is from the modem.
Check with your telephone company that the telephone line quality is good enough
for VDSL transmission. If G.hs is disabled in the Prestige, then make sure the
Prestige and the remote DSLAM have the same VDSL parameters. Use the CI
commands (refer to the chapter on VDSL commands) to check your VDSL
parameters such as band plan, band modifier, channel type, encapsulation mode,
VPI/VCI numbers, QoS parameters and service categories.
Reset your VDSL line to reinitialize your link to the DSLAM. For details, refer to the
Table 32 on page 128 (web configurator) or Table 65 on page 212 (SMT).

Password (be sure to use the correct casing). Refer to the WAN Setup chapter

Verify your WAN settings. Refer to the chapter on WAN setup (web configurator)
or the section on Internet Access (SMT).

If you use PPPoE pass through, make sure that bridge mode is turned on.

Check the schedule rules. Refer to Chapter 28 on page 246 (SMT).
