[c-nsp] 827 noise margin

[Dan Letkeman]

Hello,

I have an 827 router that seems to have noise issue's after a while
and i'm wondering if it is the device or the line? The noise margin
drops down after a week or two of use. If I restart the router the
noise margin is back up to about 7 dB.

This is what is looks like after a week or two:
