   UNITS       "0.1 dB"

   STATUS      current
   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."

       set to a non-null value, then rows SHOULD be created in
       xdsl2ChannelStatusTable, xdsl2PMChCurrTable, and all other tables
       indexed by a channel index.

   DESCRIPTION
      "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."
