Ezzer, I don't know why your post showed up as a new topic rather than as a reply... but I've merged them together. Very odd!
I agree. Downstream attenuation of 26dB is good.
HOWEVER.... this is still an ADSL Max line which has been identified as so bad that it's gone down to a fixed 512 connection speed.
Broadband1 - a few of us have said to you in your other thread, that the Sync speed is nothing to do with your IP or bRAS profile.
Please don't confuse the two... in fact forget about IP / bRAS profile for the moment, they are totally irrelevant to this problem you're having, so there's no point even talking about them until your sync speed has risen again.
I'll explain it.
Your sync speed... i.e. the speed your router and exchange have decided to connect at, has fallen and now appears to be permanently stuck at 512k (576k).
This is because the system known as "DLM" (dynamic line management) has counted so many errors on your line that it has put emergency measures in place and restricted you to 512k to see if that helps to keep it from re-syncing too frequently.
We never really got to the bottom of whether the line was now stable or not.
If it is now stable, BT needs to reset the DLM settings for your line i.e give it a second chance!
If it is STILL NOT stable, BT needs to send an engineer round to you.
Next time you speak to BT (i don't know how often you ring them to try and get it sorted), don't accept anything related to "bRAS or IP Profiles... waiting x days for the profile to update". Stress that this is the actual SYNC speed that is limited to 512 and has done so after a line fault. They should be able to see that your line is on DSL Max and it isn't just a simple case of re-submitting an order for a DSL Max upgrade!
