I see what you mean about the ES count, around 6-7pm especially. Very noticeable. Have you figured whether it is caused internally or externally? Or have any correlation to, say, street lights or heating?

For upstream - yes, that will be the UPBO mechanism in action. Right now, you have reduced upstream power (which I guess I expect) but you also have reduced downstream power (which I don't).

Not internally of my own equipment, I suspect its related to my neighbour upstairs, they start using their washing machine and other stuff after 6pm.  From what I can see based on tbb graphing data, smokeping and real usage, the errors are not large enough to affect my service so I have left alone at least for now, but I havent done any serious testing tho.

My US ES count is very similar to when I first had this pair live, its averaging barely 1-2 ES a day.

nope, my US power changes on every sync event, its never the same.  Hence my theory it is something dynamically adjusted based on whats happening on other lines.  Of course the operational range is probably governed by the attenuation, the nope is in regards to it never changing.  The difference between the lowest power I have seen and highest is about 1mbit attainable of US sync.

Yes, so I think it will be something other than UPBO that'll be responsible for it. Unless perhaps the measurements of the line length produce slightly different results each time. Unfortunately most modems do not report the various UPBO related stats.

Your crosstalker is now wondering where has all that extra sync they had before the power outage  gone to ? Mr Chry hang your head in shame for robbing them of 6Mbps  ;D

this power outage 48k properties suspiciously close to property count of previous one, they refused to confirm over phone if the same infrastructure was to blame

ordering a UPS cause im not happy with the state leaves my pc in and possible damage to pfsense unit.

for the curious i am at the exact same sync speed so i still believe the line is banded now.

Assuming you don't want to maintain a local supply to keep all the equipment running then a fairly simple UPS, that will signal an orderly shut-down, would not be too expensive.

Not for me the US power can swing from 4.7dB to -0.3dB though still think the Billion 8800NL version 1 has a firmware issue when displaying the correct Upstream power

 :hmm:  b*cat is all kerfuddled. Me thinks N*Star has misunderstood . . . This thread is about the failure of the mains electricity supply in the city of Leicester.
