      How Does DLM work and Wotsitdo ?

      I'm on the max package and on ADSL2. I'm using a US Robotics router which handles negative SNR numbers very well ( no dropouts or page freezing ). Using theDMT tool I've been connecting at anything up to 9 Mbs. Last few days this has slowly dropped to around 5.7 Mbs. Can anyone tell me how DLM works, because I think that may be the problem.

      Regards, JT.

      If you have used DTM tool to lower your SNRM and hence increase your sync speed, you will have increased the errors on your line. It is possible that your line is on the DLM trial, if it is then DLM may respond by lowering your sync speed untill the errors decrease to the point that DLM is happy (no idea what that level is or if DLM decreases speed directly or increases target noise margin).
      While this trial is in progress, it would be best to remove your SNRM tweak and let the router find it's own speed. If you do not, there is a risk that DLM will continue to reduce your speed, as you tweak your noise margin down further, and you will end up with a poor speed.

      Once the speed is reduced, will it raise it again if the number of errors improves, or am I stuck with it ?

      If you do not attempt to fight DLM with the DMT tool then it should rise to the point where your line errors are low. But this is early days and we are all just waiting to see what happens. If you are on DLM, there is no point in phone Sky as they will not interfer with it while the trial is on.

      Any idea how long the trials are likely to last ?
