Thanks for your details explanation dude, appreciate the info, very interesting. The connection is stable and is faster then 90% of New Zealand according to Speedtest.Net, so I'm happy with it and don't really want to start fiddling with firmwares and other tweaks just to push it 2-4mbsp further.

The capacitor type things are a line testing devices which telecom use for line checks. I don't know if they affect VDSL or not but they are not essential and not all lines have them. I took mine out and there were no adverse effects. My advice would be to remove them.

alright, i may tinker.. im not keen on disconnecting anything and risking it not reconnecting though.. it did take a few hours to even get this much of a stable sync rate...

Wow. That's some of the worst wiring i've ever seen. I'd wager with a bit of instruction from people on here, you yourself could probably do far better.

eXDee: Wow. That's some of the worst wiring i've ever seen for a job. I'd wager with a bit of instruction from people on here, you yourself could probably do far better.


I could indeed. I don't have a roll of cat5 handy anymore to just go and to it though.

The whole point behind letting chorus do their thing is firstly, it can't be spun to blame me. And secondly, i'm not technically allowed to with it being a rental.

Ah well, time for a nap it would seem. The slippery roads seem to have claimed a powercut.

Maybe I'll have more eventful stats in the morning ....

In the ETP the capacitor type thing is a device that helps with line testing. In a jack point the capacitor type thing is actually a capacitor that is used to separate the ring tone from the incoming line. Removing it won't cause any problems with DSL and probably won't cause problems with most modern phones (which have a similar capacitor built in). But it's not going to cause any problems either so I'd leave it alone.

so, after the power cut last night, been dropping in and out all day.. no lucky 1mbit sync for me this time..

turns out, there was a slight bit of miss communication, and the tech was dispatched today to deal with a bad sync speed... thus, he turned up to the cabinet, saw a 45mbit sync and left. did not make contact at all.

wasnt until i pressed snap that i found out, he had been and gone.. starting to get the feeling i need to sit on the cabinet waiting to see a tech and throwing spike strips at it to stop them from running off!


one would think, he would have noticed the connection consistantly dropping afer 5~20 seconds.


captured this from telnet today

excessive errors.. who would have guessed?


there is now a 12 hour test on the line, and we will make progress on a tech tomorrow morning (snap wouldnt put the order through to have a tech explicitly told to visit the place without the big report)

onto questions about the ETP, cable comes into the place in this box


(little google on this thing says its for coax, so that is a tad confusing if this is not the ETP, then i cant for the life of me find one - there was a digital antenna installed before we moved in, and its not a cable area so ild say the option of it being coax is counted out.)

the house is a cojoined rental, so need to have a chat to the neighbours before i go poking around under their side to trace the cables any further.


as for under the floor, heres the cable that comes out of the jack. clearly it isnt a cat cable at all.




oh, and just for kicks, heres the stats from the modem..




im getting to the end of my tether with this.. 3rd day in a row making myself or someone else available all day for the tech to turn up.. increasingly feeling sorry for snap, since they arent to blame for chorus lack of attention, failure to communicate and just general uselessness!

Here you go... get into the gray box and I bet you'll see more joints in there. That's where you splitter will need to go - on the bare incoming black gel-filled cable. Then you run your CAT5 or 6 to the dedicated VDSL jack. As long as you match your pairs correctly you'll be off and laughing in no time. Your splitter should have same writing as the one here http://www.trademe.co.nz/computers/networking-modems/other/photos/a-641577654/p-247779719.htm , so you connect your incoming line to Orange&White pair, Green & White Pair to your newly installed CAT5/6 cable that will go to VDSL jack (make sure your punch down the cores of CAT6 you're connecting to to the right pins on the jack - pins 4 & 5, coded blue and bluewhite) and Blue & White Pair to your existing Phone Line with a few gel filled scotch locks. That is all there's to it.

Not sure why but I think last graph I have posted was rubbish, as you could see that graph was stuck on 8db SNR while in the line stats the SNR was 13. Modem was powered down yesterday and have re-synced at 44.4 with SNR of 12, Latency: Fast and INP 0. Now graph shows only around 6 CRC errors per minute.

But what problems would you envisage with higher CRC error rate, say 15 or 20CRC per minute? And is there a significant difference between DLM1 & DLM2 ?

The tech really should have eliminated the tru-rip cable (the flat white cable).

It isn't the right impedance and will affect VDSL frequency's badly.

Again, a new cable (Cat 5e minimum) needs to be run directly from the ETP to where you want the modem. This is not me recommending, this is what Chorus are actually told and PAID to do. Yes it is peanuts but regardless, if a Chorus Quality Assurance guy checked this connection the tech would be made to fix it all up because it simply isn't up to spec.

6CRCPM on DLM-1 is close to the limit of being pushed back, a 15~20 will indeed shove you back VERY fast.

and yet, a tech who didnt even have any cat5 handy was sent out...

nice to know the name of the wire, i have always just called it speaker wire.. i made it absolutely clear to snap what cable was in there.. including photos, so hopefully they will pass it on..

any idea how one pulls out a quality assurance guy? would love to have their comments on the workmanship lawl..



once again, a case inwhich chorus techs have appalled in their performance... 5th time in a row for me over the years...

We think 6 per minute is ok. The main difference between DLM-1 and DLM-2 is the latency - DLM-2 had 8ms latency. Whether that's something noticeable depends on what you're doing. You'd lose a little speed too.

It's all random. And the sad thing is this job probably won't even get QA'd. The QA fellas are more keen on a tech's penmanship than his actual work. It sucks really.

Don't let this issue slide by, moan and moan until the tech returns.

slide by? im getting to the point of having snap on speed dial..

i do have, no connection currently.. unless busts of 10 seconds, and then a change of ip addresses can be regarded as usable internet..


that is truely a shame then.. was hoping i could find a way to stir that pot up..




as someone who his dyslexic, and does have bad penmanship, ild be very unimpressed with getting spoken to about it while mr numpty working along side of me doesnt give a flying pig as to the quality of his actual work... afterall arent they a lines company! shouldnt the err... lines be the priority? not penmanship...
