Yep, pretty standard to run phone on Blue and DSL on green, likely a splitter is installed.

 

 

 

DM me your address, I'll compare in chorus's end against neibouring connections to see if stats are about right.

I would be expecting about 20-30 there, 50+ if your lucky. looks like MDF layouts are horrid for your particular street. (likely goes through feeder cabinet and back)

 

few pairs around you showing a bit of a dip, so i suspect it may be possible there is a OP wider fault..

Is this something a chorus tech can fix? Fibre rollout not coming this way until 2023 - so don't exactly want 5 years of crap internet.

Yes, i would work with your provider to do a slow sync rate fault.

Does anyone know why I can't sync with VDSL profile 8b?? I have tried multiple times but it just won't sync. Am wanting to change profiles to try and stabilise my connection

So, I had the good fortune of sitting down with one of the Chorus people to look at my VDSL line. The sheer amount of diagnostic data is astounding. Also the automatic analysis and suggestions by the HW! So turns out that my 1.8km to the cabinet (measured by the attenuation) is actually 950m on the physical design drawings. So there was enough "other stuff" on the line to actually double my attenuation! I thought I had pulled all extra cabling off my phone line already when I moved in and connected it to ADSL (back in the day). But turns out the person who did the phone lines was a master cabler...NOT!! So instead of pulling all extensions from the central distribution point (as about 75% of them were and I have no clue why the house had a phone jack in every room!), there were two extensions hidden behind a telephone jack. I removed those and proceeded to replace all cable caps (or whatever those things are called) as I could see some traces of rust. The result was, that I went from 2.2/18Mbit to 3.3/30mbit (and much more stable connection)! Needless to say I was stoked. The Chorus report still shows some frequencies are degraded but that can have a number of other reasons including RF disturbance. My current theoretical max should be somewhere around 40mbit. If I could I'd pull new wires but that is next to impossible with the way the house was built. 

 

Now... before anyone goes and rings their ISP or Chorus... this information is not available to them and even Chorus doesn't readily have that information at hand. There are estimates that show about 100k copper lines are significantly not performing as they should in NZ. The likelihood is, that it is the cabling on the property. So make sure that your connection is clean. Inspect your phone line meter by meter -like I did- and make damn sure some clever cowboy didn't think it was a good idea to splice an extra cable in just behind the wall, where the fireplace is. Also remember that after any work on your line the DSLAM will think the line is unstable due to the number of reconnects when you disconnect the line. It will take days or a week to resync and slowly start increasing your throughput as it recognises you have a stable connection again. 

 

So happy hunting and good luck!

You are 100% correct.

 

there are some things We have in terms of automatic analysis that one ups chorus, they saw what we had and loved it.

 

 

 

Some of us has had exposure to the extra tools chorus have and we sit here and go why, can't we atleast know bits.

 

a great example, DLM.

 

if DLM is not happy with a line, it will go to a degraded state where it simply stops running and is an indication a field tech is outright required.

 

This is one thing assure can see.

 

 

 

 

 

Most recently, last week. i had an issue start up all of a sudden, disconnections and slow speeds. noise margins moving about but testing as good line.

 

to chorus, this would have been not a fault on their network.

 

 

 

 

 

Eventually i got time at 7am before work to pull apart the ETP. there was a HR fault in one of the joins on the splitter.

 

Chorus's tool offered to providers indicates there was no fault at all.

 

 

 

Within those 10 mins that i sniped and recrimped, all fixed. ddDLM is yet to catch up to that.

 

 

 

I rant a little here, but my role is literally all about performance of customer's connections and what can be done smarter. the few details of data i do have access to are mined and turned into literal gold.

I guess there is a reason why fibre is the thing to go for. (....still waiting and when it gets here it will still be a fight getting it in (complex install)) 

 

Copper is just an outdated tech. I wonder if adoption of Fibre would be even quicker if they could strip all that copper out of the ground and re-sell it.

 

Anyway, Chorus would love to debug all those lines but as you point out it is VERY individual. You need people that are interested, that know their stuff and if it is on property there is nothing an ISP/Network Provider will do. So it's all up to you and sometimes pure luck.

Yep exactly, which is unfortunate.

 

 

 

 

 

With fibre, chorus have the Checkmate platform open to  RSP's.

 

Take for example, a broken fibre, this will report quite clearly to us. unlike copper that it could be many different errors.

Can anyone comment on these VDSL line stats? A lot of the details are meaningless to me. Bearing in mind the distance to the roadside cabinet is a little over one kilometre, does anything look out of the ordinary?

upstream bin allocation is rather on the low end side....

 

 

 

Otherwise looks pretty good for distance tbh.

 

 

 

 not much of a snr hit which would tell me your lines pretty clean too.

Thanks, but you'll have to translate "upstream bin allocation" into plain English for me. smile

upload speed looks lower than it potentially could be.

 


I'd put this down to possibly any bad internal wiring or the modem chipset simply not being the best.

The internal wiring was redone and now the modem is basically hanging off the demarc. This is the second modem I've tried (DrayTek DV130). The Huawei HG659b had a slightly higher sync rate, but hardly much. I won't lie, that upstream rate is depressing.

Heh. It's better than mine. And your downstream is double what I get too. :-D
