xdsl2LineBandStatusLnAtten – VDSL2-LINE-MIB

Object

column 0.1 dB Unsigned32

Line Attenuation.
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 of that band during initialization.
              
When referring to a band in 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 of
that band during initialization.
              
Values range from 0 to 1270 in 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.
