Both ADSL fed from the exchange and VDSL fed from the street cabinet =
have a portion provided over fibre... where is the magic separation =
point that moves it from not being "fibre optic broadband" to being =
"fibre optic broadband"?

The =A31500 is what BT are quoting as an average based on distance. The =
cost works out as something like a fixed =A3500 setup + a per meter =
charge which varies depending on how they have to get from the cabinet =
to your property + any other civils/construction work required along the =
way.

For example, grass verges are much cheaper than pavements which are in =
turn cheaper than roads. They also have set charges for things like =
drilling through a wall depending on whether it is internal or external =
and if it is concrete or not concrete.

There's a list of the current OpenReach Excess COnstruction Charges at =

Unfortunately, only OpenReach can install these as part of the "FTTP =
on-demand" product. Any OpenReach service provider customer can order =
these, but it is OpenReach (part of the BT Group) that does the work.

OpenReach are required to sell space+power at the exchange for =
co-location of service provider equipment as well as selling all of the =
services that they sell internally in to the wholesale and retail =
divisions in the BT Group. It is then up to the service provider to =
aggregate customers and arrange their own backhaul, which obviously =
means that exchanges with a lower density of customers and/or which are =
more remote and therefore more expensive to arrange backhaul from are =
less attractive to unbundle.

What generally ends up happening is that the service providers competing =
with BT unbundle the more attractive exchanges where it makes financial =
sense to do so and then use BT Wholesale services to cover the other =
exchanges with more expensive, slower products that include a lower =
monthly cap due to the high cost of backhaul on the BT Wholesale =
network.
