@Zarjas yeh, I realise a port isn't assigned until someone places an order - but the spreadsheet indicated that 100% of lines would be able to get FTTC (ie. if I understand correctly, no-one would just be unable to order because of the cabinet they're on not being upgraded). So given how many lines there must be in this area I'd be surprised if a single 288 cabinet could handle the load in the long term, and would fill up. Seems like it would be pretty bad future planning on BT's part

.
Anyway, I went on a little walk with my digital camera to take some photos of the cabinets so that I could compare them to the photos and also show you. A couple are missing because the camera crapped out and just saved blank white

.
Turns out I should have gone to have a closer look at this 'fttc' cabinet before, since it would have answered my question. It has a sticker on the front saying it's vodafone property!

. It's a derail, but I'm curious what kind of cabinet it could be then? It's C on the map below btw.
Not that it really matters either way I've marked on a
google map withthe cabinets I found (some of them are in the streetview, a couple are new). I think they all look like PCPs but I could easily be misidentifying. I've uploaded pictures here:
