Its abit difficult to see if bitloading has been reduced where SNRM drops in the compressed graph.

Can you take some more snapshots using the expand function around the SNRM drops in D2 and D3.

Examples of mine compressed and expanded in D1 are attached

Can you also provide the hlog for completeness.

Hi Custard , hope these are what you require, ive expanded the entire graph as best i can ..

The bit loading looks good and as there is no deficit where the SNRM shows those downward spikes, I'll say that there is nothing to be concerned about.

Cross-referencing the dual-graph with that of the QLN, some posts above, reinforces that opinion.  :)

Hi Burakkucat :)

based on info and graphs supplied , would you say theres a possiblity that my interleave will be reduced or knocked off ?
...im hoping to regain my speed of 59 down 17 up that i used to have .

HI Perry.

Sorry you seem to have shown the wrong areas in the graphs. I Was looking for tones 3000-3900 in D3 and possibly tones 1300-1800 in D2.
Try to take these when your overall SNRM drops.

For the HLog leave the image collapsed so that all the tones show in the graph.

Once you have a few days of data you may be able to detect when the RFI/REIN occurs by checking your SNRM per band.

Lastly you might want to upgrade to the latest firmware. Peeps on here are reporting that it works better at bitswapping on noisy lines.
Nb: your line does not so much noise compared to some of the longer lines!

That is the question, isn't it!  ;)

Unfortunately I can't answer it. If the circuit is "well behaved" and stable, there is the possibility that the depth of the interleaving will be reduced, step-wise. It might be worthwhile posting the pbParams data for a number of successive days and then Bald Eagle1 may be able to offer an opinion . . .  :-\

:paperbag:  Oops, b*cat has committed a folly.  :-[

I should have asked you for the Connection Stats, from under the Telnet Data tab in DSLstats and not the pbParams.

(Now where is that Analytical Eagle? Methinks it is best to keep my tail tucked inside this brown paper bag, to avoid any spurious tail pecks.)

Or a bank hoilday migrate to warmer climates away from troublesome kittens  :)

Perry do you have any white extension cable (cw1308) into the NTE5 ?

Custards makes a great point on wiring.

no probs , here you go

... just before posting this there was a massive drop in down SNRM from 6.8 to 5.9 , also a drop in max downstream rate to 57552.

This would be the time to get that bitloading/SNRM data while the SNRM has dropped!

 :D I think I need some spectacles!!

Looking at that I don't think that those spikes would cause you to lose so much speed as you haven't lost bitloading on too many tones.

If your SNRM is dropping about 6pm and then rising again at 10pm everyday then this might just be normal variation. This will be apparent once you have stats over a few days.

Did any electrical appliances get switched on at the time when your SNRM reduced.

shouldve gone to specsavers .... lol just kidding  ;)

i remember putting the gas boiler on for the hot water around that time, i thought of that , but no change after i knocked it off.
...shame becouse it was holding at 6.8 for the last 2 days  :(

Migrated to the garden today for the first time this year.

The grass was knee high.
Cutting through that lot certainly kept me warm (spurious tail pecking was the last thing on my mind) & there's still a lot more to cut tomorrow.
