Stats are as above on a bt business line that is just plain pants.

Are those stats any good or are they rubbish?

I could live with the slow speeds, but quite a lot of times when browsing the page just times out like ive lost all connectivity.
 
Noise Margin: 14.9 dB 5.9 dB

The downstream SNR as quoted above is way over the usual 5-7dB that ISPs set.

Should be syncing a lot higher on the downstream if this were corrected. Working out why it's been set high might be tricky. Maybe the line is instable and it's been set high to allow for fluctuations throughout the day.
 
It rather depends on why it's been set at almost 15dB. If you can monitor the SNR & Connection speed with something like Routerstats you might find that it's not unstable at all but has been set high by BT for an issue that occured in the past. It could also be that BT set business broadband with a higher SNR for stability.
