In reply to a post by jelv:

If the stats shown on SamKnows are accurate surely it's going to be more than "the odd 20CN-only exchange knocking about". There are 5508 ADSL Max exchanges and only 1786 ADSL2+ / WBC enabled exchanges (which are included in the first figure). I can't see them getting anywhere near upgrading all of those in the next two years.

Indeed. My original 21CN target was Q3 2011, which back in 2007/08 I thought was far too far off. Fast forward to Q1 2012 and it's scheduled for the end of June. Three quarters late in other words. IF they can't get the original targets in on time, and are now focussing more on fibre to prevent the Sky and Virgin cornering the market, then there's little chance of there being very few 20CN exchanges by 2014.

It will probably end up being a local and national government subsidy which moves things, allowing BT to get the upgrades without putting up the cash (which by the way it gets from the customers screaming for faster broadband).
