Hi, i have heard recently that in basic terms VDSL uses a different back haul to ADSL and the way it was explained to me was "if a cabinet in a street has 20 ADSL users and 5 VDSL users that with each technology using it's own back haul , VDSL is obviously going to have less contention and therefore improved performance again over an existing ADSL connection"
Unfortunately after searching different terminology i have been unable to find any documentation that supports this or confirms this, if anybody has knowledge of the back haul between a cabinet and the exchange any comments would be appreciated
My own experience with VDSL users who have moved from ADSL is they seam to be quite happy with the speed where with ADSL we were getting a few more complaints and the speeds are only 27248/9888 kbps for VDSL compared to the 18/0.9 mbps from ADSL so not a huge increase in down speed but a big increase in up speed and if i recall correctly zero complaints on internet speed since changing to VDSL - which lends some support to the above analogy
thoughts please
