Well it’s not had the DLM again.
I’m a bit confused with dates but on one day the ISP were doing line tests every 2/3. Hours. I thought it was just dropping but I compared the times with them and they were identical.
That must have been Wednesday as it had DLM action Thursday and Friday but not since. It’s also interesting that the comment about NM being increased rather than interleaving. So I’m leaving it alone, and see what happens, but I’ve put current stats up as at this morning. That might help as there has been no actual resync for 2 days.
Thanks for all the input,
