Now I've looked at the photo on a large screen rather than my phone, I don't think it is an AIO cabinet, just a copper PCP. Possibly the DSLAM cabinet is to be added later. Unfortunately the site that normally provides such information doesn't think Cab26 exists yet so I can't check dates! Not sure if @pippincp has access to different information.
According to some search results on Google, you can start your own ISP, but after seeing the prices that have been paid, maybe not feasible for 200 or so households.
