I'm way late to the party here, as I have just discovered this forum as well as the Superfast Berkshire site, but am very pleased to have done so -- a wealth of information and some very knowledgeable posts.
Having lamented the state of Broadband in Pangbourne for years, (getting about 5 Mbps via my ISP), and a bit fearful of casting my lot in with TalkTalk, (one hears things) despite them advertising roughly triple that speed, it was with great surprise that I came across this News Release from BT dated Wed 23rd May 2012, in which it states that Pangbourne (and Wargrave) are now scheduled for an upgrade to 20Mbps by Spring 2013:
I'm guessing that this means that the Pangbourne Exchange will be upgraded to CN21, though whether that extends to FTTC is something I'm not clear about. Given that the News Release talks about this development bringing the coverage in Berkshire to 87%, and it talks about the need to "work with the public sector" to reach further, it kind of sounds like this may be where they're drawing the line in terms of commercially-profitable development. Presumably that's where Superfast Berkshire will move things beyond that point.
On a practical level, while the speed quoted will be a huge benefit, just up the hill in Tilehurst there are folks reporting upwards of 40Mbps and beyond, through both BT Infinity and Virgin. Presumably that's the sort of speed one gets from FTTP, and not just FTTC + copper, but I must admit that I'm still trying to get to grips with the differences between ADSL/ ADSL2/ ADSL2+/ CN21, etc., and how that translates into performance. My house is 400-600 meters from the exchange according to Kitz, so we'll see.
Anyway, really pleased to have found this forum, and thought I'd mention the good news for those who happen to be in Pangbourne or Wargrave.
