a Select Operation and then select Over POTS or Over ISDN.
b Specify the ADSL Modulation standard in use.
– Auto will revert to ADSL2 if the line doesn’t support ADSL2+ or revert to G.DMT if line
doesn’t support ADSL2. Select Auto if using Annex M.
– Annex M
–G.DMT
– G.Lite (only available if Operation is Over POTS)
–ADSL2
– ADSL2+
– T1.413 (only available if Operation is Over POTS)
c Select Transport Mode and then choose the transport.
ATM specifies Asynchronous Transfer Mode. PTM specifies Packet Transfer Mode. Auto will
query the DSLAM for the transport mode.
4 If you specified VDSL as the DSL standard, do the following:
a Select Operation and then select Over POTS or Over ISDN.
b Specify the VDSL Profile profile (for example, 8a, 12b, and so on).
– Auto will query the DSLAM for the profile.
–8a
–8b
–8c
–8d
–12a
–12b
–17a
–30a
c Select Transport Mode and then choose the transport.
ATM specifies Asynchronous Transfer Mode. PTM specifies Packet Transfer Mode. Auto will
query the DSLAM for the transport mode.
5 Select G.INP Setup and then specify whether the unit will advertise upstream or downstream
G.INP support to the DSLAM. If the selection is changed, the modem resyncs in order to apply
the new setting.
6 Select Vector Mode and then select Full, Friendly, or Off.
Vectoring technology is used on VDSL2 connections to reduce cross-talk 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 single-line VDSL circuits only (not available for bonded, not avail-
able for ADSL2). Vector Friendly mode is suggested when there is a need to emulate CPE
incapable of full vectoring, but which have been designed to synchronize to a vectoring
NOTE:
You may not see all of the settings above. The available selections vary, depending on the con-
figuration and installed options.
NOTE:
Enabling G.INP only advertises support to the DSLAM. It does not guarantee the connection will
use G.INP because G.INP is specified in the CO configuration.
