hwAdsl2SCStatusSnrInfo OBJECT-TYPE
SYNTAX OCTET STRING (SIZE(0..512))
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The SNR Margin per sub-carrier, expressing the ratio between
the received signal power and received noise power per
subscriber. It is an array of 512 octets, designed for
supporting up to 512 (downstream) sub-carriers.
The number of utilized octets on downstream direction depends
on NSCds, and on upstream direction it depends on NSCus. This
value is referred to here as NSC.
Octet i (0 <= i < NSC) is set to a value in the range 0 to
254 to indicate that the respective downstream or upstream sub-
carrier i has SNR of: (-32 + Adsl2SubcarrierSnr(i)/2) in dB
(i.e., -32 to 95dB).
The special value 255 means that no measurement could be done
for the subcarrier 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."
