Just to expand on what Jimbo and Pem have said, this is a matter of investment in equipment, except, whereas BT can get away with installing at the exchange site, the investment by NTL has to take place at every Mux cabinet, of which there are many thousands, as the equipment has to be able to send the signalling down the copper going to the house.

Whilst the BT network has copper right from the exchange to the subscriber, the NTL network has fibre running most of the distance, so these upgrades can't happen centrally with minimal investment.
