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
The VDSL line type can be configured by selecting maximum Interleave
delay of Downstream or Upstream direction. Basically, there are three
types
No limit
