About a month ago I restarted my modem like 10 times to see if it would go from DLM-1 to 8b to 17a profile which was a pretty crazy theory and all I did was go back onto DLM-2 and got higher latency. But this seems to have reset DLM so about a week ago I got DLM-1 back. Just got back from a trip today and noticed the speed was crazy fast so I thought it must of been on 17a. Had a look and it was I couldn't believe it. I think reseting DLM could help as I was on a solid DLM-1 for 5 months and it didn't ever change.
Huh! That's an interesting theory which may well have some merit! Hard to say tho, you might have been put on 17a faster if you didn't do the 10x resets...
But I was on the same profile for 5 months and a week after being put back on DLM-1 and I do mean 1 week to the day it swaps to 17a I mean thats why I tried doing something just to see if it would do it. Everyone was like your attenuation is too high but now we know 6-7dB is not too high for 17a profile.
Wow, that is interesting ! you must be good a decent local loop. Also the SNR margin I believe would not matter as much as your CRC rates, which is what really would dictate your DLM profile.
