So 2 cabinets serving my street - one has FTTC available, the other doesnt.
Note that you are being told that 14% are connected to cabinet 1, while 85% are not connected via any cabinet at all. These are known as "exchange only" or "exchange direct" lines.
Why cant we all be on cabinet p1?
Because that is the way that wiring has developed over a century plus?
Perhaps your cables don't physically go near cab 1. Perhaps the ducts go the other way along the street. Perhaps cab 1 isn't big enough. Perhaps your wiring was put in place before the GPO started to use cabinets.
Again, sorry for being stupid, but I dont see why we cant have fibre..
The simple answer is because your line doesn't go via any cab at all ... and it costs money to re-route lines via a cab, or to provide an entirely new cabinet. That money is enough to make it commercially unviable (ie BT won't make enough money from your subscription to pay for the work that needs to be done).
In this case, cab 1 was upgraded as part of the commercial rollout, and there have been *no* cases of re-routing done in the commercial rollout, and *no* cases of adding an extra PCP (to convert EO lines like yours) in the commercial rollout.
However, the financial case for these two activities changes in the presence of BDUK subsidies, such as those provided by "Connecting Devon & Somerset".
Is there anyway around this to get the 85% onto P1?
There is indeed a way around it. It might be to put you onto cab 1, but it is more likely to add a new PCP outside the exchange, and move EO lines onto that one.
If it is to be done, then it will be part of CDS ... and those will be the people to contact to find any further information. If it doesn't happen now (in phase 1 of CDS), then it might still happen in a future phase, as more funding gets added.
