I've been toying with the idea of going VDSL for some time now and dropping the normal line and go VOIP enabled. I'm within the VDSL range, as the cabinet 'isn't' that far away (I realise physical distance doesn't represent actual).
These are my stats from my current dsl router:
Data Rate 14329 1240
Noise Margin 12 12
Output Power(dBm) 125 189
Attenuation(dB) 18 5
