reported. For each band in which XLOGpsds is reported,
XLOGBANDSds contains a triplet of (start_subcarrier_index,

"Reports the downstream Xlog(f) as one value per sub-carrier
group.
For each octet, the values, 1 to 250 represent the Xlog
values of +39.5 to -85 dB in steps of -0.5 dB
using an offset of 80 where:
Xlog(f) = (xlogps - 80) * -0.5
A first special value (255) indicates that the Xlog(f) for
this sub-carrier group is undetermined.
A second special value (254) indicates that no measurement
could be done for this sub-carrier group.
A third special value (0) indicates that the Xlog(f) for
this sub-carrier group is greater than or equal to +40.0
dB.
A fourth special value (251) indicates that the Xlog(f) for
this sub-carrier group is less than or equal to -85.5 dB.
The data node is updated only in L0 link state.";
