I'm sorry that but I really dont know how.. as mentioned previously this has happened to me a few times.. the first was back in the days when Ian wild was known for being able to get resolutions to problems and he (Ian) even used a contact fairly high up in BTw, but still drew a blank.
The bottom line as told to me was that BTw did not have any SLA on latency.. and they dont seem at all interested in the routing or mapping of the ATM backhaul.
Rizla (a knowledgeable adsl experty type bod) also had a similar problem in the past which plagued him through several ISPs.
He even tried migrating to Zen, who also couldnt get BTw to do anything... in the end he had to go LLU before his situation was resolved.
IIRC even A&A have witnessed this type of thing before... but I cant recall if rizla tried A+A but I do know he mentioned them at one point.
It is annoying that this happens and I can sympathise because I've been there. Each time its happened it has cleared after about a month or so... All the other cases Ive seen bar one usually clear after a while... the one that didnt clear and that was intermittent was rizlas, which is why he went LLU.
If you do find anyone that has successfully managed to get a remap that does clear this it would be interesting to know how.. (or even if it is one of those that just cleared itself like several others I have seen) for others in the future.
Ive just tried googling RAS remapping and didnt find anything of much use, other than an A+A case where it was mentioned amongst about what must be about 20 cleared and rejected cleared with BT
>> but i would like to contact them
Unfortunately BT Wholesale will not speak to us plebs and will only talk to their customers which is the ISP. Its only if the ISP can get SFI (I mean the old and proper type SFI of the likes in Wolverhampton) involved will you get to speak to someone in the know about this type of thing, and then they may speak to the end user direct.
Getting what I call real SFI involved is damn hard these days, and the only direct contact Ive ever had with them is when things got really dire in a case which involved many users and speeds frequently down to well under 100 kbps... and even that involved a very long & hard fight
I hope that my comments are not being too pessimistic, nor discouraging, because I really do hope that you can get something done about this, and the one thing in your favour is that you are with one of those ISPs that do have a good CS record for rejecting BTw's so called clears and will try all they can for their EUs.
