Apologies for the delay in response.
here are the stats off MDWS
Is 456240DSF you?
Looking at those stats over the past 20 days. I cant see any indication that that particular line has been reset.
INP has been at 3.0 for at least the past 20 days, and interleaving delay also hasn't moved from 8.
Im also confused because that line is showing a current sync of 57728 for the past 11 days which doesnt tie up with stats you posted above.
I was wanting to see what was happening with your SNRm and how much it varied over the course of the day, but I cant see any indication of that either, although there is a break in logging a couple of days ago.
As said in a previous post I'd need to see your SNRm variance before commenting further, but going off your stats alone - certain DLM intervention can cause an increase in SNRm - ie banding - I cant recall the exact figures off hand but Im sure one of the bands is in the 74Mbps region. If you have been banded at 74 then that could account for the 73265 sync with an SNRm of 12dB. Based on the hard stats youve posted I cannot see any reason why DLM should be coming down so hard on you.. and that is why we need to look at SNRm variance and the amount of errored seconds.
The other thing that springs to mind... have you been swapping out routers and/or doing lots of resyncs? If so DLM could be punishing you for that.
A warning that I may not pick up on this immediately - I have so much family stuff going on right now Im not sure if Im coming or going... and am miles behind with forum posts :/
