OctetString
An array of up to 512 complex H(f) linear representation
values in linear scale for the respective transmission direction.
It is designed to support up to 512 (downstream) subcarrier
groups and can be retrieved in a single segment.
The number of utilized values in the downstream direction depends
on NSds; in the upstream direction, it depends on NSus. This
value is referred to here as NS.
Each array entry represents the imaginary component (referred to
here as b(i)) of Hlin(f = i*Df) value for a particular
subcarrier group index i (0 <= i <= NS).
Hlin(f) is represented as ((scale/2^15)*((a(i)+j*b(i))/2^15)),
where scale is xdsl2SCStatusLinScale and a(i) (provided by the
xdsl2SCStatusSegmentLinReal object) and b(i) are in the range
(-2^15+1) to (+2^15-1).
A special value a(i)=b(i)= -2^15 indicates that no measurement
could be done for the subcarrier group because it is out of the
passband or that the attenuation is out of range to be
represented. This parameter is only available after a loop
diagnostic procedure.
Each value in this array is 16 bits wide and is stored in big
endian format.
