The below is based on the address checks (and some number checks) I've done for each property.
Imagine a long, straight road in the middle of nowhere, with the cabinet on the left hand side, along with all the telegraph poles.
The cables are underground until they reach this new cabinet, which is at the place where the lines change from underground to overhead. The poles have been in for as long as I've lived here, and carry large multipair cables, plus small junction boxes for the drops. There was no noticeable change to the overhead copper when the cabinet went in.
The first pole is marked DP309. The rest with only a number.
There is an underground cable across the road I think, leading to about 12 properties, several hundred metres away. They can all get VDSL, 80Mb.
30m along the road, pole 1 has a junction, and a dropwire to the 1 house on the other side of the road. They can get VDSL, 80Mb.
Pole 2 is about 20m further, and there is a T junction here. There is a cable that branches off, to follow that road. The house several hundred metres along that road can get VDSL, 80Mb.
Pole 3 is 30m further, and is just a pole.
Pole 4 is the same.
Pole 5 has 2 dropwires across the road. Can get VDSL 80Mb. This is my immediate neighbour.
Every property up to this point shows VDSL, 80Mb
Pole 6 is 50m further, and is "mine". Total distance back to Cab 21 and DP309 = 300m. I'm actually connected to Cab 11, about 5-6 miles away.
Up to here, everything except my address is VDSL, 80Mb.
The overhead cables and poles continue along this road for about 800m to Pole 14, and 1A on the other side of the road. All the properties here can get VDSL, around 50Mb
I've crosschecked address\phone number for several of my neighbours, including people further away, and they all have Cab 21 and VDSL in both checkers.
On the face of it, the whole thing makes no sense. So much so, I'm drawing a picture to send with my spreadsheet.
