yes I read the same thing this interferes with sub loop unbundling, I think the arguments in favour are the fact sky, talktalk etc. are not using sub loop unbundling they have instead chose to rent openreach equipment, if all those isp's can be persusaded on the merits of vectoring and agree to it I would hope ofcom can see common sense and not block it.
The way we are going, with almost all BDUK money going to BT for FTTC coverage, I agree. Common sense, right now, suggests (for FTTC now, and FTTP in future) that we're heading for a single physical infrastructure setup, with virtual competition layered on top.
I can't help but think that we're going to need new definitions for "market N", as the presence of (say) TalkTalk or Sky in future (on existing Market 1 exchanges) may be limited to only having TalkTalk or Sky backhaul, with no physical LLU or ADSL2+ equipment, as exists currently. Same goes for FOX exchanges.
Also in these SIN documents it suggests the current modems are all currently vectoring compatible so no CPE swap should be required also interestingly it states they SRA compatible as well.
Do you have a link for either aspect? I understand how important the CPE equipment is for vectoring - and have seen Alcatel trumpeting that they have a solution that doesn't require a re-roll of CPE equipment.
SRA is also interesting, as it doesn't get much of a write-up (in a practical sense) in DSM techniques, in either the Broadband Forum or in the NICC description of UK networks. Do you have anything that points to real experience?
