Don't believe VDSL Vectoring is enabled in NZ. Capabilities is probably in the hardware but vectoring  is not compatible to LLU (local loop unbundling) currently which is ashame.

 

 

They could at least enable it on the cabinets where there isnt any other ISPs gear in place for those of us suffering terrible performance and waiting on fiber.

Talking to the right people within chorus who do want to make use of all these technologies, there is actually a long process for adding the capability in terms of testing.

 

 

 

Look at ddDLM, that was quite some testing, and still we had random issues that came up which had to be taken back to suppliers to work out.

 

The other problem we have is, Capitalization happened really early in NZ, some of our gear simply is not capable of preforming the new features on copper. In this case i'd put the question to you, Would you rather chorus put the big dollars into Fibre rollouts or did an austrila and go "FTTN" everywhere like 2004!

That is a somewhat valid point if its not just a software upgrade to make it happen then it would take $ away from important things. But there will probably be people on copper for a very long time, particually in rural areas so it wouldnt be a total waste researching getting the gear they have doing it.

 

Not sure how a reduction in pairs being used will go affect vectoring. At the moment I think all pairs but the 2 unused ones coming to my house on the cable down the drive have VDSL on them, crosstalk is massive on it. That is where vectoring is supposed to help out. I expect that once fiber comes along the number of DSL connections will drop overnight (well however long it takes for the installs to happen) to none, meaning that the others on that bundle down the road who dont get fiber will find themselves on a much better connection. Meaning that vectoring might not matter too much long term.

Got my first improvement overnight with SNR dropping from 12 to 6dB, sync up from 59/9.5 to 70/12.5, on 8b profile to an Ikanos card with 10dB attenuation. Had pretty much given up on ddDLM so that was a nice surprise.

Yes, nice to see some DLM action at last.

 

Previous sync was 73/10 14ms ping with a 6dB SNR Margin (lowered with Draytek modem command - see my previous posts).

Ah yep, we are still on 12db

 

 

 

 

 

 

 

Hey guys, I've just seen this, does this mean our box has been upgraded???

looks like ddDLM has moved you from 12dB to 6dB on the upstream.

 

 

 

Upstream is commonly the first channel ddDLM hits as it can drop alot lower before becoming unstable.

I have a suspicion that your line is a multiple :( I suspect this is why you probably can't have VDSL.

82mbps on 8b! That's something I've never seen before. Really don't understand why your line hasn't flipped to 17a.

 

I saw a tweak too:

Previous sync was 68/14 at 8/8 SNR. So I've dropped to 8/5dB SNR, grabbed another few mbps of sync, but gained even more interleaving. More speed is welcome (particularly the upstream, which is starting to look almost respectable), but this wasn't really what I was expecting... is this interleaving ever going to go away?

Draytek have just released new Firmware 3.8.1.2 for DV130 
I've been using Modem 8 for since Vectoring was added to the FW
Getting performance as seen in previous pages

 

So thought I'd try some other firmware versions with ddDLM now well entrenched and update to 3.8.1.2
I downloaded 3x different FW's, installed them all using Factory reset file
NO SNR tweaking used in these tests.

 

STD = I think most users would normally use this, 8b Profile the fastest upload connection

 

Modem 4 = (vectoring support) 8b profile, faster DS connection, slower US connection then above

 

Modem 8 = (NBN optimised+vectoring support) 17a profile, fastest DS connection, 2nd fastest US, Attenuation up 2db, giving some FECS errors on DS, hard to tell on US as these figures must come from Cabinet ? as they are remembered even after a factory reset.

 

17a profile for me at least giving better download connection speed, not necessarily better experience, I think a few packets are getting resent as Speednet test aren't as efficient as 8b profile (achieved vs achievable)

I need to STD FW again to see if the Upstream is just a one off

Yes, 82Mbps on 8B was looking quite good but after monitoring it all day the CRC errors started to get a bit scary. The Draytek SNR adjustment plus DLM lowering it early this morning was taxing the connection too much...

 

NE CRC Count : 8370    FE CRC Count : 10
NE ES Count : 4634      FE ES Count : 8

 

I gave up and reset the modem VDSL SNR Margin from -50 back to 0 (default) just after 5pm tonight. Modem restarted with this....

Lost 8Mbps down speed but the SNR default setting should kill the CRC errors. The default Near End SNR Margin has dropped to 6dB (from a previous 12dB) so maybe ddDLM will take another look at our stats and try pushing us to 17A.

 

Our Far End SNR is still up around 12dB which may be the blocker because everything else looks fine.

Would that be MPF based on https://www.geekzone.co.nz/sbiddle/8357?

 

 

 

 

Something like that: "Bridged taps can also exist in Chorus wiring external to your home where wiring may be looped down your street."

 

You probably need to get a Chorus tech out to confirm this. Maybe log a fault for drop in upstream sync, but be prepared to pay for NFF. And if you do, make sure you are there to ask the Chorus tech questions.
