Lorenceo:

 

The Vigor 130 can't SNR tweak on VDSL. The DSLAM ignores any SNR related commands from it and negotiates at the value set by Chorus (9db is most common).

 

Thats a shame. Chorus were digging outside my house the other day, and my line disconnected.

When it came back up I noticed my speed dropped quite a bit :(
