Is vectoring technology the likely solution to these problems then? (crosstalk) If so, does anyone know if it is something that is planned to be deployed any time soon?

In reply to a post by Icemansin:
How much will FTTP on demand cost?
I'd guess that the monthly costs will probably be broadly comparable to FTTC, adding a bit for the higher speeds, but the installation costs are likely to be several hundred pounds at least, probably nearer a grand.

Vectoring is designed to help negate the crosstalk, and BT is planning it, but not for a couple of years.

There is a good reason the speeds for distance versus connection speed on http://www.thinkbroadband.com/guide/fibre-broadband.... are so pessimistic, this takes into account worst case cross talk on VDSL2

There could be a problem with rolling out Vectoring. The next stage will be going up to Profile30 and that will require, potentially, almost twice the processor power for the software modem on each line. Add in Vectoring which needs to monitor cross talk and then generate an appropriate cancellation signal across the whole band - that will require further processor capability.

Are the current lines cards capable of the increase in CPU load? Potentially not.

It is wait and see, five year life span probably for the line card

If UK is to meet EU 2020 targets and still rely on FTTC, then profile 30 and vectoring will both be needed.
