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. |
