Re: FttDP
The distribution point is the point the cable from the cabinet terminates and is hooked to the (usually 1-2 pair) wire feeding your building. So in your case it's probably in the joint box you mentioned. If you look at the telephone pole, you'll see a junction box at the top. That's the DP for the overhead feeds (most poles will also be labelled with the DP number, for example "DP 358")
Seeing as they're running fibre from the exchange, I can't see why they can't also run the 48V feed down the duct from the already existing batteries, to supply power to the DP nodes.
