Trying to figure out a couple of things:
1) Who use GEA currently? My guess is TalkTalk/Sky? I assume the rest of the ISPs use a BTw provisioned service.
2) Does an ISP have to pay the £2k+VAT cablelink fee per exchange? Does that get handed over right at the exchange itself? Is it possible to 'trunk' these connections to nearby exchanges using a different BT product?
The reason I ask is that I'm interested in the economics of GEA for providers with the coming BDUK rollout
For example, a very small exchange that was enabled with FTTC from OR under BDUK. Perhaps 1500 lines. No LLU coverage from Sky/TalkTalk. Suppose Sky were to want to provide access under GEA.
Could Sky instead have their GEA connections terminated at a nearby exchange for an economical price, or would they have to install equipment and lease backhaul at each exchange? With 21CN, it shouldn't be out of the question to allow much more affordable 'location-agnostic' termination as a specific circuit doesn't have to be provisioned. Just change some IP headers, at least in theory.
Excuse typos and waffle -- coffee hasn't quite kicked in yet
