Title: High ES on Upstream
Post by: g3uiss on March 27, 2015, 04:56:24 PM
Has any one views why I suddenly have a high Upstream high ES while DS maintains its average. The SNRM doesn't seem any different to the norm either

Taking the generic view of the problem you have mentioned . . .

As all xDSL circuits currently transiting over a metallic pathway operate in the frequency division multiplex mode then I suggest that there is some frequency specific aberration to your circuit.

Specifically, there is some form of interference affecting only those frequencies that carry your upstream channel.

(Not a great deal of help, I acknowledge.  :)  )

Thanks for the comment. I thought that, I'm surprised it doest show in the SNRM per band data.

Does DLM normally apply interleave on US only if required ? I have no degradation in upstream performance.

I really don't know. The operation of the DLM is an unknown, to me. Perhaps others could help out?  :-\

Even tho the US errors stopped just before midnight, DLM gave me US Interleave at 0650 !

I guess if it works properly it should revert quickly as there aren't many FEC's either.

Thanks for input

Perhaps you will keep note and let us know when the DLM relents?  :)

Yes will do. As it stopped the errors before midnight, the caution counter should stop it, but who knows !

DLM doesn't consider FEC errors, at least in my experiences it has ignored the millions produced by buggy ASUS firmware until their recent beta on a forum which has resolved it so far for my line.

As asked, went back to Fast Path on US think it took about 13 days

Thank you.  :)

Now that is interesting -- because there have been other mentions of the DLM taking ~14 days to relent and then removing the applied conditions that were required after a one-off bout of circuit instability.

Yes B*CAT have encounterd the same duration many times when my line was on the pre g.inp interleaved profile, 14 days was like an eternity lets hope those days have gone for good  :mad:

I don't think it will be a surprise if I say that N*Star was one of the persons whose circuit of which I was thinking . . .

Hopefully Tony will soon have G.Inp enabled on his ciircuit -- if it is not already applied.  :)

Hmh

Not sure if ECI cabs are being updated. Do they need to access the cab as I pass it each day. I think I'm right longer lines like mine will benefit. Is this less effect from short bust errors or is there a speed benefit as well ? Tony

I can say that the Huawei DSLAMs were upgraded remotely and no access to the cabinet was required for that task.

As for the ECI DSLAMs, there is a big cloud of uncertainty . . .  :-\

The other was me !!!
DLM has done this on 2 occasions.
Each was 14 days. :(

Think this suggests the caution counter is somewhat longer than originally suggested. My errors only lasted about 6 hours and all in the same day.

Guess we must expect 14days if no further errors appear in that period, if they do it can go on for ever, I know my DS took 9 months !
