      Why has the format for line attenuation values etc changed??

      Hello

      I have noticed something weird - I think it changed a few days ago (??)

      I would log into the SKY Router as you do and go to Maintenance > Statistics and you would check out the line attenuation and noise margin etc and it was values like 14.1 dB or 15.4 dB etc

      I checked recently and it has a weird format like DS1:9.2 DS2:21.6 etc and I have included screen capture images - if anyone can decipher what this means and I will appreciate it.

      Thanks in advance

      It has been mentioned before:
      What the hell does this mean?
      Other than educated guesses we don't really know.

      The "new format" just shows the attenuation and SNRM for each of the bands (3 down and 3 up) that VDSL2 uses. The bands alternate U0, D1, U1, D2, U2, D3. On a short line there should be SNRM values for all six bands but on longer lines some of the upper bands will have an SNRM of 0.0dB indicating that the band can not be used. On a very long line only U0 and D1 will be active.
