| 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. |
