Here you go BOAC
BT Infinity
"The "BT Infinity" network will be able to offer broadband speeds of up to 40Mb download speeds for those who have a
FTTC connection, this is the type of connection that BT will be installing for most of the UK. However some who receive a
FTTH connection will be able to receive fibre broadband speeds of up to 100Mb."
The murky bit that introduces a degree of confusion is that FTTP is fibre to the "premises" which can be any building that the customer is willing to pay for.
The miles of twisted "crud" is down to where you choose to live and if you are indeed miles from the nearest cabinet then you can't expect to live in the sticks and enjoy the benefits of living in a town and vice versa. The twisting in any case gives the copper pair shielding from EMF interference unlike the untwisted crud in your domestic wiring hence my earlier comments that the home domain fouls up BB to a surprising degree.
I trust BOAC is not "Better On Ancient Copper"
