Acceptable Noise Margin Results?


[link to this post]
 
I have been having problems with my upload and download speeds off and on for a week now. I think I have it narrowed down to a device on my internal network, but want to rule out any DSL problems.

I was looking at my DSL modem diagnostics and ran across the noise margins. Are these results acceptable?

Re: Acceptable Noise Margin Results?

Useless without sync speeds to put it into context.

Usually the Target NM at sync time, decided by ISP DLM, is of interest and how it varies thereafter.
