BT did say earlier this year re: VDSL that they plan to install an extra 2,800 street cabinets between 2016 and 2020/21 specifically for "network rearrangement purposes" (i.e. for long copper lines, Exchange Only Lines (EOL) or to improve broadband speeds etc.)
I would be very surprised if this was all BDUK - in fact I suspect a fair part will be in their "commercial" FTTC footprint.
That misses the point I was making. The cabinet is already there. It's a small PCP cabinet that serves a few streets, including half my street. I recall the engineer saying about 350 lines go to this PCP (I may be wrong there). Then over 300 lines pass right by this PCP to the next, much bigger PCP. This larger PCP has around 900 lines. Both have their own accompanying Fibre twin. The Fibre twin for the larger PCP is always at capacity. The smaller PCPs Fibre twin is half empty.
Common sense says upgrade the smaller PCP to make it a larger cabinet, and connect those 300+ lines. It would save needing a 2nd Fibre twin on the larger PCP as a bunch of those moved lines would now be served by the half empty Fibre twin.
This achieves a few things.
Frees capacity on a full DSLAM
Uses capacity on a half empty DSLAM
Possibly saves installing a new DSLAM next to the full 1
Increases speed for the 300+ moved lines and moves them within range of G.Fast (from the pod). I'm not holding my breath on them going deeper into the network here. Not an affluent area, or densely populated.
Plans to install new cabinets ignore these instances. There's situations like this up and down the country. Of course the full fibre cabinet is commercial, and the half empty is BDUK. No surprise there.
