Is this a parameter that is set at the exchange or is it done remotely, if so which group has controll? Reason I ask is that I was on 4608 for ages and since the last fault it has been set at 1152. Also, do you know how the Noise margin is set? It was around 9db for ages also. Cheers, Nick

Can't guarantee this but it's the best I can tell so far.
The downstream rate will run at it's maximum it can unless it reaches a preset cap. The caps I believe can be set remotely but it's by the LLU engineers so thats usually 2 or 3 levels removed from who you get through to initially.
Margin is dependant on the capped downstream rate, otherwise it seems to target 6db. When you had 9 it suggests you were capped and had a small leeway for extra speed, not much and it may not have been stable.
Just to add to that mine aims for a 6 db target magin but when line conditions are good it can sometimes be as high as 10. THis would give me well over 6 meg but instead the line is set to sync at 5632kbps which was the rate i got when I first got changed to LLU.
The line sometimes switches down to 5500 when line conditions are bad but climbs back to 5632 soon after.
Snow sounds like yours is set to just about the right level of capping. If it was higher you'd get faster at times but when the signal dropped a little lower then it would disconnect you. In general a more stable connection is better than one that can go faster but disconnects.
LLU capping should be thought of as the IP profile system on ADSL Max, just that it's not automated and normally doesn't vary the profile or cap depending on the line stats.
