Specifying DSL settings
1
From the Tests & Settings menu, touch the Modem Settings button.
2
Select DSL Interface and then specify whether to use the RJ45
connector or T/R/G (Tip/Ring/Ground) as the DSL interface.
3
Select xDSL Technology, and then select VDSL, ADSL, or xDSL
(Auto). The Auto setting queries the DSLAM for the technology.
4
Select Analog Technology and sect xDSL over POTS or xDSL over
ISDN. The Annex A Bonded modem is automatically set to xDSL
over POTS.
5
Do one of the following:
–
If you selected ADSL as the Technology, select Standard &
Annex and then specify the ADSL standard and annex (such as
Auto + Annex J or ADSL2+ Annex M).
–
If you selected VDSL as the Technology, specify the VDSL
Profile (such as 8A or 12B).
6
If you selected either VDSL or Auto as the Technology, select VDSL
Vectoring and specify Full, Friendly, or Off.
Vectoring technology is used on VDSL2 connections to reduce FEXT
from other pairs in a binder group resulting in higher downstream and
upstream rates for all the pairs in the group. Vector mode is available
for VDSL circuits only (not available for ADSL2). Vector Friendly
mode is suggested when there is a need to emulate CPE incapable
