Description: SNR Margin is the maximum increase in dB of the noise power received at the ATU (ATU-R on downstream direction and ATU-C on upstream direction), such that the BER requirements are met for all bearer channels received at the ATU. It ranges from -640 to 630 units of 0.1 dB (physical values are -64 to 63 dB). Unit: 0.1 dB
What is adsl2SCStatusSnrMargins?
Reports, as a per-subcarrier array in units of 0.1 dB (physical range -64 to 63 dB), the SNR margin at each subcarrier - the extra noise headroom the line can tolerate on that tone before failing its bit-error-rate target. It's a detailed diagnostic used to pinpoint which part of the frequency band is marginal on a noisy line.
