VDSL-Config:Margin-Config subprofile
Introduction
Parameter settings in this subprofile are used to configure upstream and downstream
margin requirements when the
dsl-type
parameter, in the AL-DMT profile, is set to
vdsl
.
Default settings
The following listing illustrates the default settings of the AL-DMT:VDSL-
Config:Margin-Config subprofile.
[in AL-DMT/{ any-shelf any-slot 0 }:vdsl-config:margin-config]
target-noise-margin-up = 60
target-noise-margin-down = 60
min-noise-margin-up = 40
min-noise-margin-down = 40
max-noise-margin-up = 100
max-noise-margin-down = 100
Parameter descriptions
The following table describes the functions associated with the available parameter
settings in the AL-DMT:VDSL-Config:Margin-Config subprofile.
Parameter Setting
target-noise-
margin-up
Specifies the upstream noise margin, relative to 0dB that must be
present before the line can initialize successfully and rate adapt
during VDSL operations. The valid range, in tenths of a dB, is 0
through 320 (0dB through 32dB). The default setting is 60 (6dB).
target-noise-
margin-down
Specifies the downstream noise margin, relative to 0dB that must be
present before the line can initialize successfully and rate adapt
during VDSL operations. The valid range, in tenths of a dB, is 0
through 320 (0dB through 32dB). The default setting is 60 (6dB).
min-noise-margin-
up
The noise margin setting that is used if the minimum bit rate cannot
be achieved on the line using the target noise margin.
The valid range, in tenths of a dB, is 0 through 320 (0dB through
32dB). The default setting is 40 (4dB).
min-noise-margin-
down
The noise margin setting that is used if the minimum bit rate cannot
be achieved on the line using the target noise margin.
The valid range, in tenths of a dB, is 0 through 320 (0dB through
32dB). The default setting is 40 (4dB).
