DESCRIPTION
"When referring to a band in the downstream direction, it is the
measured difference in the total power transmitted by the xTU-C
and the total power received by the xTU-R over all subcarriers
during Showtime after the diagnostics mode.
When referring to the upstream direction, it is the measured
difference in the total power transmitted by the xTU-R and the
total power received by the xTU-C over all subcarriers during
Showtime after the diagnostics mode.
It ranges from 0 to 1270 units of 0.1 dB (physical values are 0
to 127 dB).
A special value of 0x7FFFFFFF (2147483647) indicates the line
attenuation is out of range to be represented.
A special value of 0x7FFFFFFE (2147483646) indicates the line
attenuation measurement is unavailable.
This object reflects the value of the parameter following the
most recent DELT performed on the associated line. Once the DELT
process is over, the parameter no longer changes until the row is
deleted or a new DELT process is initiated."

Several objects in the table refer to NSus and NSds. For

subcarriers according to the selected implementation profile.
For ADSL, NSus is equal to NSCus-1 and NSds is equal to NSCds-1.
The parameters in this table MUST be updated after a loop

rate adaptation on Upstream. The ratio refers to the available
data rate in excess of the Minimum Data Rate, summed over all
bearer channels.
Also, the 100 - xdsl2LConfTempChan3RaRatioUs is the ratio of

Upstream direction. The sum of rate adaptation ratios over all
bearers on the same direction shall be equal to 100%."

"VDSL2-specific subcarrier mask. This configuration
parameter defines the restrictions, additional to the band plan,
to determine the set of subcarriers allowed for transmission in
both the upstream and downstream directions.
The parameter shall describe the not masked subcarriers as one or
more frequency bands. Each band is represented by start and stop
subcarrier indices with a subcarrier spacing of 4.3125 kHz. The
valid range of subcarrier indices runs from 0 to at least the
index of the highest allowed subcarrier in both transmission
directions among all profiles enabled by the parameter
xdsl2LConfProfProfiles.
Up to 32 bands may be specified. Other subcarriers shall be
masked."

DESCRIPTION
"For ITU-T Recommendation G.992.5, this configuration
parameter defines
the subset of downstream PSD mask breakpoints, as specified in
xdsl2LConfProfPsdMaskDs (PSDMASKds), that shall be used to notch
an RFI band. This subset consists of pairs of consecutive
subcarrier indices belonging to breakpoints: [ti; ti + 1],
corresponding to the low level of the notch.
The specific interpolation around these points is defined in the
relevant Recommendations (e.g., ITU-T Recommendation G.992.5).
The CO-MIB shall define the RFI notches using breakpoints in
xdsl2LConfProfPsdMaskDs (PSDMASKds) as specified in the relevant
Recommendations (e.g., ITU-T Recommendation G.992.5).
For ITU-T Recommendation G.993.2, this configuration parameter
defines the bands where the PSD shall be reduced as
specified in #7.2.1.2/G.993.2. Each band shall be represented
by a start and stop subcarrier indices with a subcarrier
spacing of 4.3125 kHz. Up to 16 bands may be specified.
This parameter defines the RFI bands for both the upstream
and downstream directions."
