Which is the most expensive to replicate.
It is the laying of the ducts and construction of the civils network that is most expensive.
When BT upgraded and continue to upgrade, all they have to do is pull the old cable out and new cable in, of the civils network they inherited and plug in the new kit either end.
NTL/TW had to construct all of their network from scratch blah,blah,blah
