FoD is the same as GEA FTTP service at the exchange end and as such is sent to the wholesale operators, BT Wholesale, Sky and TalkTalk over the GEA cable link that they purchase at the handover exchange.
Given Sky and TalkTalk have not started to offer FTTP in areas where it is the only option, I cannot see them bothering with FoD, it is something that will not appeal to their high volume sales market.
