Title: MDWS - QLN Graph - Bad?
Post by: William Grimsley on June 30, 2016, 05:07:33 PM

Hi,

Is my QLN graph bad, it looks all over the place?

Your QLN graph has changed since the last recorded one on the 9th of May 00:00 though the D1 Band is much better to-day than on the 9th of may, D2 Band looks shaggy as to-day

So, does that mean my line is better performing?

There is less noise on the D1 now but more noise on the D2 band so it's neither better or worse than it was on the 9th of May

Ahh, that's good. I'm getting less Downstream ES, haven't had one for days now. My Hlog looks good.

There still seems to be this random up and down in the Upstream SNR Margin though...

Well, for some reason there was 305 Downstream CRC's within 15 minutes on my line yesterday evening but have had none since, very strange...
