Hey guys,

Exciting day it is today, Seems Vectoring is livening up on some locations.

mt pleasant being a notable location as of this morning.

Seen some impressive results, I'm collating a few numbers but at a skim...

seeing about 20Mbit gains on good lines (pegging out at 100mbit)

Longer lines are seeing 10ish on some cases (I don't have many examples of this as of yet so unfair to comment too much)

Looks like currently the example lines i've pulled out are only protected on upstream so no massive gains there but hopefully a bit more of a background noise reduction on errors.

With G.INP going live, seeing all compatible modems dropping down to no interleaving!

Hopefully our chorus folk around here might wanna drop some numbers that aren't specific to what i can see - This would give a more broad look at the improvements!

Keep an eye out for what DSLAM's this hits next, I for one am excited to see it out and would love to see a rural example (WAK/C is a great example i'm sure guys ;) )

For the curious, there's some information on Chorus' site about this.

Good to see. Haven't seen many lines with huge gains just yet, though.

Throwing caution to the wind: Would be cool to see it enabled on TIS/BK

Is this a trial or is this the actual rollout? Would be good to see some dates for completion? Especially Kirwee :)

make use of that new tower ;)

This is the initial trial on live lines, rollout due soon. Much like what happened with ddDLM.

Oh come on you say that without sharing photos? It must be pretty glorious.

Still yet to see any change on my parents connection - still at 110/50Mbit.

That line isn't going to see any improvements really unless the profile maximums change.

Any indication of what "due soon" means? Weeks? 1 - 2 months? Longer?

Also, any list of which cabinets will be upgraded?

This is their Pilot.

As mentioned in the first post, on Mt Pleasant, CHCH. (MPL/AL DSLAM-03)

Next steps

We’re consulting with the industry via the TCF, on the implementation of VDSL vectoring and G.INP. We’re proposing to pilot both initiatives on active VDSL lines in Ethernet DSLAMs, within a Christchurch Chorus non-fibre area. The pilot testing here will produce a small outage for your customers as their modem restarts.

After the pilot testing confirms our expected improvements, we propose to roll out VDSL vectoring to all Ethernet DSLAMs in areas without our fibre. Conditional on TCF approval, this should be done by the end of the year.

Your service delivery manager will update you with test timings once confirmed. Contact them (or your TCF representative) for any further queries.

so..... anytime? chorus have not defined.

Will either change (vectoring or G.INP) roll out in areas that don't currently have Chorus UFB, but are scheduled to get it in the future?

I gather from the other thread that areas who already have fibre installed by other operators (e.g. Enable) will be getting the upgrade, while those of us who will be waiting another two years for a Chorus rollout won't. A little annoying if true.

Details have indicated chorus intend to compete against UFB offering's in these areas.

I personally Don't agree with this and feel like concentration should be done on non UFB areas.

But a business does need to make money, and if Vectoring can provide decent 100/50 links without fault.... well that's not a bad offering...

Same sorta story as Chorus UFB areas where there is pushback on copper orders that don't have valid arguments for why it should not be fibre.

Thanks. Made my thoughts in an edit to my post above while you were posting. Slightly galling to have flash new linecards going into cabinets in areas where people have had access to UFB for years, though I guess I can understand how the decision makes sense commercially. Meanwhile I get 17Mbps upstream with a 4db SNR on a 150m run to the cabinet in Mt Albert because the whole street is stuck on VDSL while we wait for fibre.

Edit: wait, did I understand your post correctly? You mean Chorus intend to use vectoring/G.INP to compete with UFB in the non-Chorus areas, but won't be rolling it out in areas currently waiting for Chorus UFB, yeah?

That's the rabbit hole we are going down...

IMO, vectoring has massive value for urban situations first off. They are more highly affected by crosstalk.

Rural should be the second or first target situation as the copper out there should make for some great sales stats...

Competing against UFB (non chorus areas) should be flat out the last thing ever for customers.

For a business though... the more delays in getting this equipment out there, means less business potential.... so would not surprise me if it goes non chorus UFB areas first.

EDIT:

posted in other thread from a ex fieldtech.

exchorusfieldtech:

As far as I'm aware, in areas where Chorus isn't the LFC, they fully intend to deploy equipment to try and compete - this means that in future, theoretically we should see G.Fast technology anywhere LLU isn't happening and it's viable for deployment, and Chorus Fibre isn't an option (Most of the Waikato, Christchurch and Whangarei/Northland).

Is chorus competing against enable in christchurch ? As fibre was rolled out in my area place Chorus changed the equipment in the cabinet unleashing my VDSL to over 108/44 which better than a equivalent fibre plan at the moment. But i am still getting fibre installed while its free anyways.

Can chorus make vdsl go even faster and undercut the faster fibre plans? How fast can VDSL actually go?

Fibre can't compete with copper when it comes to capacity and latency and I am sure many other things
