The line quality is determined by using the SNR (Signal to Noise Ratio) and
applies to VDSL line connections only. SNR is the ratio of the amplitude of the
actual signal to the amplitude of noise signals at a given point in time. The higher
the SNR is, the better the line quality. Please manually adapt SNR margin
according to line quality and distance to get better performance or replace the
line with new one.
Click on the drop-down list and select the SNR to be used. Configures SNR
margin of Downstream or Upstream.
SNR margin value: 6 dB to 24 dB
Default value: 6 dB
