FTTC question

Possibly a daft question this, but I've not stumbled across anything that hints at an answer. If, by some gigantic fluke, BT decided that the exchange to which I am connected was to be part of the proposed 1.5 billion FTTC roll-out would that mean every cabinet connected to that exchange would be upgraded? Or would they cherry-pick the cabinets in the most populated locations? Or is there some technical/commercial reason that would make having a mix of FTTC and non-FTTC in the same exchange impratical or nonsensical?

My local exchange serves just under 4000 residential properties spread out amongst a few semi-rural satellite villages/towns of varying size. So I'm wondering if the 3.5 km to the cabinet in my village would likely be seen as too much effort.

No one knows nor is likely to know for a long time yet. Doubt there will be any definate deployment proposals this year.

I would think a rural exchange which serves a number of villages, and only has a total of 4,000 residential lines, will be way down the list.
If the target is 40% of the population (a figure mentioned a while back), I can't see BT needing to go anywhere near towns (smaller than maybe 40,000 people) to hit the 40% figure (they could do most of that figure just by enabling London, Birmingham, Glasgow, Manchester, Liverpool, Newcastle, Leeds, Sheffield, Coventry, and the other towns with populations over 200,000).

Whilst the scrap value of copper is quite high (quite possibly higher than the new cost of fibre), and there's no doubt there's going to be a few million metres of the stuff could be reclaimed from just your area, I think the install costs will be far too high for BT to bother with those of us out in the sticks.
I don't even think our exchange (which serves around 22,000 lines) will be on the list.

The logical upgrade path for marketing purposes is to tackle those cabinets with larger numbers (not sure what number you'd need here) of customers AND 2-3km away from the exchange as that will provide the greatest impact. However the most likely path is to tackle those with existing fibre ducting that can be 'blow' easily.

sounds like my exchange then.

20k lines on it with average attenuation over 40db.

How you you know the average attenuation on your whole exchange?

Thanks all for the responses. Sounds like I'll be stuck on the wrong side of the divide. I'm clutching at the straw that because there's a school in the village it'll be deemed necessary to make FTTC available for that. The slimmest of hopes I know!

The school may already have or may get a fibre based leased line, but thats not dependent on FTTx.

apperently its stored in BTw database and isp's and engineers have access to it.

My exchange has commercial properties near it and the vast majority of residental properties hooked to it are on the other side of a canal.

Its not the exchange is the green cab density that's the important number as you are effectively moving the DSLAM from the exchange into the cabinet. If you have a small number of cabinets then I agree you'd be ideal unless the copper is all on the 'street' d-side rather than the 'exchange' e-side.
