The answers above are all correct, based on BT's current strategy for rollout of FTTC in both commercial areas and in the starting phases of the BDUK rollout.
We have also seen BT start to adapt their strategy to cope with EO lines, by adding new PCP cabinets. This allows the existing FTTC strategy to then apply to those new cabinets, and has been seen in Cornwall more than anywhere else - but will still be part of the BDUK rollout.
However, there are signs that they are beginning to consider further "infill" strategies that would be included within the BDUK rollout, and cover the cases where properties are too far from the normal PCP location.
I mentioned this yesterday, on a different thread
This isn't a thing that they are doing within the commercial rollout, and haven't yet done so within the BDUK rollout.
However, one village is known to have subsidised an upgrade in their own area, where the two FTTC cabinets are to be located (or perhaps already have been) with the SCP (secondary connection point) rather than the normal PCP, in order to gain the extended range. Unfortunately, SCPs are rare in the network.
But there is at least news of new solutions appearing on the horizon, though we have no idea how the new solutions are to be used.
One presentation, from Openreach NGA manager to Lancashire county council, lists some things for coverage of the final 3%. See pages 11 and 12 of this Lancashire presentation.
Another presentation, from a chief engineer in Openreach responsible for access-network strategy to NICC on their open forum day, The presentation is here, on NICC's website. Page 9 has some solutions (FTTPoD, FTTdp, and wireless for rural access), while page 18 mentions some "BDUK infill" solutions, including "NGA Amplifiers", an "all in one FTTC cabinet" located deeper in the network than the standard PCP one, wireless cabinets, and more.
Who knows when, or even if, any of them will get deployed in reality. But it is good to know that solutions are being thought of - it means they are starting to think about the final 10%.
(The unamed village I mention is indeed Binfield Heath, but I forgot its name - thanks zom22)
From those presentations, I note the use of both an "all-in-one" FTTC cabinet that is located somewhere lower in the network than an existing PCP/FTTC pair. That seems like they'd consider using it to create an SCP/FTTC pair. There is a mention of NGA Amplifiers too, but I haven't seen any technical description of such nodes.
Is there a "mini cab"? Yes, but we haven't seen one out in the real world. Take a look at this Youtube video
, where one can be seen around 2:40 in.
