So the question is:-
How is the interference fed into your router?
Is it via your electrical system or is it broadcast through the air?

Hi Axis, well that's the $64million question. If we can get a feel for the sources of some of these more minor/trivial occurrences, then if there is a major event, it may help point us in the right direction. At the moment it's all speculation and process of elimination and possibly identifying any patterns.
Hi Jack, not to put too fine a point on it, tick the box to save the DS sync speed, otherwise if/when something happens, we don't have the graph to look at which may give us a vital clue 
I doubt whether this morning was a fridge for example, we'd have probably seen a step back up when it stopped. The spikes might be a fridge, but equally could have been a light going on, with a lot of cloud about it'll be quite dark around that time.
The line dropping isn't the only thing that will influence the Target SNRM, the error rate can as well, which by the way at the moment is insignificant (good news), miniscule even.
As far as your ticket/PN you could just update the ticket to say line monitoring is ongoing to try and identify any events causing drops in sync. & I know James will not be ignoring this, he'll feel that there's not a lot he can do at this point until we can get a handle on something for him to get his teeth into.
I'll comment about the graphs more in a moment. Just sending you a PM.

That RS Noise Margin graph is a lot better now. What I think will be best, is whilst you are around and able, post the DMT SNR-monitor snapshots. Leave RS running 24/7 when you can, saving the Noise Margin graphs and DS sync graphs.
When you are not around to run and post DMT, post the RS NoiseMargin plots as soon as you are able, en bloc would do. Obviously if something happens on the sync graph post that as well.
If we spot anything "interesting" on the DMT plots then you can post the RS plot for the period to see if it adds anything to the picture. What do you think?
By the way, check the RS Alarm action is NOT set to reboot, we don't want it rushing off and spuriously rebooting if something happens!

Hi Chris,
              I have a very strong feeling that we are looking for something that isn't there, everything points to my line being good, not dropping, good error counts and a very clean line (phone) . Surely it's possible that the problem is at BT's end, the way that the SNRM acted when they reset it suggests to me a problem with their equipment, please understand that I bow to your greater (by a long way) experience and am just working by what is to me logical. The only time I had problems with my line was when the line was noisy, the rewiring seems to have cured that problem so why are we looking for aproblem at our end? When I forced the SNRM to 6dB using DMT it ran for 24 hours without a problem, I let it back to 9dB by closing DMT and 3 days later BT reset it to 6dB and we have a problem, surely everything points to the BT equipment? In my opinion we should now suggest to BT that they test their equipment by trying another reset and see what happens. I can understand if you tell me I'm wrong as I know your knowledge is far greater than mine, What I think I will do is in the morning force it back to 6dB and see what happens for a time, what do you think of this idea?, Jack.

You may well be right Jack but we can't be certain (yet) that the re-wiring has cured the noisey line, it could have been external and might still rear it's ugly head at some point.
We can't be certain what happened at the SNRM reset, it certainly looks like a possible line card issue BUT your line is currently stable, well within BT's (very loose) spec. and without further evidence we're banging our heads against a brick wall.
We're NOT just looking for a problem at your end, we're looking for any problem on the line, eliminating any minor gliches that can be connected to minor events at your end is a good thing, and also proves your line is not subject to problems from your end. Problems from the BT end can still show up in the monitoring that we are doing. Suggesting anything to BT at this instant will be a total waste of time and effort.
No I wouldn't force it to 6dB in the morning, leave things a few more days (as I said in the PM), the more evidence of a stable zilch error connection the better.
Patience is the most important thing here, if you force it to 6db now and it starts dropping all over the place your Target MAY rocket to 15dB and getting BT to do anything may be mighty difficult. I would start by reducing to between 7 & 8 dB and see what happens, but as I keep saying - not yet.
Just monitor in the background, post the graphs periodically, and enjoy your connection in the meantime.
I'm sorry that's not what you want to hear, but at fear of repeating everything, I don't think we'll get anywhere else at the moment.

Just looking at your last DMT - did that glitch at 2133 show on the RS plot?

[#8]

Have noise levels your end been getting more variable during the last 30 mins or so. Starting to get a bit noisey my end!

[#9]

I know your right but after now nearly 5 months my patience is wearing thin, will do as you suggest, cant see anything on the RS graph but attached a copy as your the expert, Jack.

[#10]

I understand, I'd feel the same. Anyway the glitch was probably a polling issue, did you by the way check that there is NO Alarm Action to reboot on the RS Alarm tabs.
I'd NEVER claim to be an expert, I have good knowledge in some areas a bit thin in others

[#11]

Hi Chris,
                "In the Land of the blind the one eyed man is King" always remember this!!
I'm pretty sure the RS settings are as you requested, Ive attached some screenshots to show them, will continue to monitor and post DMT results for your perusal, the RS results I'll keep for reference, Jack.

[#12]

First  and second for today.
The glitches at approx. 12.15 and 12.45 are possibly from an imerssion heater, the is no responding glitches on RS, Jack.

[#13]

So we have Erasmus to thank for the quote, damn .......I can't find my latin dictionary.
The Alarm Actions tab is the one, looks OK, that's how mine is set.
The trouble with spikes are they don't last long enough to always be spotted.
Trivia ~1130/1133 something "on / warming up / drifting" similar to 1048/1050 yesterday.

[#14]

The thing is none of the blips seem to have a negative effect, to see nothing I would imagine you would need to build a lab. clean room.
Here's the latest DMT shot, I can't see anything untoward, Jack.

[#15]

You better start building that Faraday Cage just in case though.
