Cable & wireless are also getting into LLU big time with their purchase of Bulldog.
They claim 4 Mb speeds over DSL!!
Also the age of line equipment at the exchange is irrelevant because the line is intercepted at the MDF and connected to a DSLAM and to the exchange line card. The telephony path is transparent to DSL. As someone has already pointed out, the oldest exchanges are about 20 years old. (Ntl's oldest are about 10 years old but without the BT advantage of regular software & hardware upgrades, costs too much money you know?)
NTL are committing a lot of resources to this project.
