vdsl2SCStatusSegmentSnr

The SNR Margin per sub-carrier group, expressing the
ratio between the received signal power and received noise
power per sub-scriber group.  It is an array of 512 octets,
designed for supporting up to 512 (downstream) sub-carriers
groups and can be retrieved in a single segment.
The number of utilized octets on downstream direction depends
on NSds, and on upstream direction it depends on NSus.  This
value is referred here as NS.
Octet i (0 <= i < NS) is set to a value in the range 0 to
254 to indicate that the respective downstream or upstream sub-
carrier group i has SNR of: (-32 + xdsl2SCStatusSegmentSnr(i)/2)
in dB (i.e., -32 to 95dB).
The special value 255 means that no measurement could be done
for the sub-carrier group because it is out of the PSD mask
passband or that the noise PSD is out of range to be
represented.  Each value in this array is 8 bits wide.
