Description: Noise Margin as seen by this Vtu with respect to its received signal.
What is e7VdslPhysCurrSnrMargin?
The signal-to-noise ratio margin, in units of 0.1 dB, that this VTU sees on its received signal — essentially how much headroom the line has before errors start. An admin investigating a flaky DSL line with frequent retrains looks here first: a low or negative margin points to a noisy or marginal copper pair.
