kitz I see you getting US snrm issues as well now. This started since the cab work?

Yeah... I just noticed myslef  - my upstream has gone crazy since whatever they did last night.   
Its normally very stable

[kitz]

Who thinks the DLM is going to hammer me?

 

[burakkucat]

E-yuck! 

That has got to be a fault! 

[kitz]

Oh...  and the capacity issues now seem to have gone!!!!!!

Bit bumpy - but for the past few weeks come evenings Ive been down to at low as 20Mbps.   It could be that everyone is out on a Friday evening.. or that they have added more capacity.

99.7% sure you will escape the dreaded hands of the DLM as the errored seconds is only affecting the upstream if it was the other way round yes I would say you would end up being interleaved with a reduction of the DS sync speed for a few days.

As for the 3% you will know in the wee small hours if your DLM has taken effect on your line.

I notice Ive lost sync a couple of times this evening - so I guess I will have to see if it notices that too

remember you are aloud 20 lost sync's in a 24 hour period it's just how close together they are within a 15 minute period that does the damage 

[kitz]

they were :/


.... and Im not sure I believe the 20 figure - plenty on here seen it happen at much less.   I think maxdsl had the DLM kick in after 5...  and yes I saw his RADIUS report from PN which would appear to confirm this

Looking at MDS you had lost 2 sync's within 15 minutes this evening and one at 5am, you should be ok

your ES looks ok for DLM (based on graph just over 2000ES a guess) but thats assuming the US has same threshold as DS.  I am curious if those errors were service affecting tho.

Kitz I am pretty confident now its ES not CRC, when I left my sync on 79987 for the afternoon barrage of noise, I had 17k crc in a 2 hour period and DLM left me alone, the ES was 500.

  @kitz  Since the downstream looks much the same as usual I would guess that it should not be a line fault but either the DSLAM or the modem. Mostly probably the DSLAM, but I would first swap the modem since that is easy and, if the problem remains the same, it should enable you to be more firm in reporting a fault.

The DLM got me and at 5:45 has applied Interleaving and INP.

I'll swap routers in a bit.



@les. Just as an aside my line fault last year only affected my upstream - and eventually voice.

[les-70]

   Thanks for the aside, I was assuming that as both up and down occur over the same two wires that would be hard to achieve.  I think voice can be different as it effectively needs a good DC path with no possibility of working via capacitance coupling.

[kitz]

Ive seen quite a few HR type faults were just the upstream is affected and downstream is ok. 

When mine got really bad, I could still sync at the 80Mbps and my downstream SNRm would be relatively flat..  but my upstream could only manage a sync in the region of 10Mbps and my upstream SNR was spikey as hell. :/

Until you can get those US errors under control the DLM is not going to return you back to fastpath and it's a case of monitoring your stats to see if you line fix's itself over the next days or call or use your ISP forums if things have not changed.

It will be interesting to see if those US errored second counts rise again in the evening time.
