Hi Woppy,
Although your question sounds a very reasonable one, you won't get an answer from the incumbent.
Furthermore it's not just the exchange that matters (which BT use for the backhaul, but much more a case of how many lines are connected directly to the exchange without a PCP Green cabinet, how many PCP's there are, and what is the maximum D side cable length from the PCP to the premises.
In other words I very much doubt that your exchange would be suitable for a FTTC solution and would probably be far better off getting your own community group to implement a

Kind regards,
Walter
