Noise Margin as seen by this Vtu with respect to its received signal in 0.25dB. The effective range is -31.75 to +31.75 dB.
What is vdslPhysCurrSnrMgn?
This metric displays the current signal-to-noise ratio (SNR) margin in 0.25 dB units, ranging from -31.75 to +31.75 dB, as measured by the VDSL transceiver on either end of the line. Noise margin indicates how much additional noise the line can tolerate before transmission quality degrades and errors occur. Operators monitor this value to assess VDSL line health and predict when signal degradation may require line reconfiguration or maintenance.
