Thanks Ignitionnet, any ideas of the regulatory reasons?
In order to bond the FTTC product would have to change considerably. At the moment Openreach sell a loop back to the exchange which stops off at an FTTC cabinet where it picks up the broadband signal.
To sell a bonded solution would either require 2 sets of line rental, be it a full line or a combination of full line and d-side between customer and cabinet which would be a regulatory change in itself, or a change to a model where a line rental element is bundled into the FTTC charge.
Either way it's a change in how the product works.
