Thats the FTTdp model in the Strategic Review, with the copper driven as VDSL2 or
better G.FAST when it becomes commercial in a couple of years. The 'dp' (distribution
point) is a pit at the bottom of the driveway - or more likely, attached to the side
of a nearby power pole, TransACT-style. 1 Gbps is a stretch - as the articles below
note, where this is mentioned its usually upstream+downstream summed, but 200 - 300
Mbps symmetric should be achievable.
