Whilst the photo Lee posted is what most would recognise, I have seen various different-looking ones, though not one like this. Hence my curiosity.
It's about 750m from the existing cabinet which serves both part of Little Walsingham and the (2km away) village of Wighton, between the two. My father's located in Wighton and connected to cabinet 1 (the one mentioned), which is due to be upgraded shortly. However as Wighton is 2km away, I suspect it's unlikely that FTTc would be available without a new cabinet. Better Broadband For Norfolk (BDUK) don't know anything about a new cabinet, and Openreach are completely opaque, but a lot of roadworks and duct clearing has been going on both around Wighton and between Little Walsingham (where the exchange is located) and Wighton. I thought perhaps this was either a new cabinet to serve Wighton, or electrics to serve a cabinet sceduled to go in. All the work and this box appearing don't really make any sense if there isn't to be a new cabinet.
