Are the dslam's capable of that without special configuration too? That's pretty cool, though if they build it the way they are "guaranteeing" it shouldn't ever have to...

VDSL2 is really just ADSL2+++++. All chipsets I know of will gracefully transition
from VDSL2 to ADSL2+ or whichever system provides the highest capacity, so I doubt
anyone will get *worse* than they would with ADSL2+. At worst it should fall back to
ADSL2+ mode.
