DESCRIPTION
"SNR Margin is the maximum increase in dB of the noise power
received at the xTU (xTU-R for a band in the downstream direction
and xTU-C for a band in the upstream direction), such that the
BER requirements are met for all bearer channels received at the
xTU. Values range from -640 to 630 in units of 0.1 dB (physical
values are -64 to 63 dB).
A special value of 0x7FFFFFFF (2147483647) indicates the SNR
Margin is out of range to be represented.
A special value of 0x7FFFFFFE (2147483646) indicates the SNR
Margin measurement is currently unavailable."
