#2 They probably would not drop it £10 month, but the difference is the extra margin would be going to the company that owns the local loop, so would be factored into ROI investment decisions for new local loop investments. Ignition has mentioned another country allows their local loop owner to sell the basic rental to consumer (think was japan?).
#5 So on BT wholesale we only have the choice of one isp? that is news to me. Even with BT owned DSLAMS isp's can still use their backhaul as is proven with FTTC, both sky and talktalk customers still go over sky LLU backhaul. I dont know how BDUK comes into this. If you talking about BDUK funded FTTC rollouts, well yes but you forget two things. (a) many of the BDUK areas were areas that had a poor economical case for "any" investment. (b) it includes the expensive laying down fibre which absolutely drawfs the cost of buying some dslam cards. Adsl dslam cards can be brought for a few houndred pounds of ebay, and not to mention they already own dslams, they would need to be relocated yes but they could use exisitng openreach fibre as backhaul back to the exchange. If isnt viable at all tho then yes scrap LLU adsl and piggy back on BT dslams. Exchange based ADSL is holding things back.
#6 Not crazy at all. Old copper from E side sold off, no more E side maintenance, and we already know BT want to move things away from exchanges, so even themselves want to do it. Do you really think free of regulation BT would be voluntarily paying for the upkeep of duplicated infrastructure, and one that has an inflated upkeep cost at that? Also I didnt say I want one for every isp, I just said the option would be there, knowing however that talktalk and co would refuse to spend, the reality is they would all piggy back on BT dslams, so wouldnbt be dedicated dslams to every isp. Also I see it as intermediate solution, I dont see cabinet based ADSL or VDSL as long term solutions, but I see it as a means of progress. Exchange based ADSL and especially wholesale regulated pricing is holding back BT the means to progress.
If I was the CEO of BT I honestly think I would refuse to rollout FTTP if I had a regulator telling me I have to sell it at X price to my main competitor and my ROI was capped at a level they are free to change on a whim. Even if ofcom agreed to something nice, they have a history of changing after a few months of whinging from talktalk.
If you think about it for a moment, one of the prime business cases for FTTP is to free one self of having to maintain legacy copper, yet if you are obligated by the regulator to keep that copper in place, that business case is down the drain, surely you can understand that. What ofcom seem to want from BT is for them to rollout fibre to the premises, sell it a cut price to sky and talktalk that gives them about 100 year payback on breaking even, and on top of that keep all their exchanges open, on top of that maintain the long E side copper runs. I think they in lala land.
