Nope. Only MSR & FTR are set in the 1st 10 days.

The SNR margin & BRAS are ongoing throughout the life of the ADSL service.

The margin should & normally does adjust as required 6 - 15dB according to any line problems & hence your sync speed. It's not set in stone in the 1st 10 days.

Well I've still got a crappy speed, I must be drawing to the end of my training period, for the most part I have to admit my speed has increased. However I have had resynchs, my noise margin has fallen into the negative and has raised as high as 9db, (this seems worse at night), this morning my router lost the connection altogether and my speed is now no better than an old dial up connection. Am I right in thinking that it will take three days at least to recover? I know that this period is about searching for the best connection for my line so again am I right in thinking that all these problems are part of that process. I am beginning to wish that I had stayed on the 1mb service, at least it was reliable for the most part.
