You're getting pretty good sync speeds for VDSL too. It might be good to try to nail down exactly where the cabinet is. You can track it down using the Chorus cabinet list at http://www.chorus.co.nz/file/12279/Existing_Distribution_Cabinet_List_May_2013.xlsx. The coordinates in that file are NZ Map Grid coordinates. You can use something like http://apps.linz.govt.nz/coordinate-conversion/ to convert from NZ Map Grid to NZ Geodetic Datum 2000 which gives a latitude and longitude that can be put straight into Google maps.


How can I determine which of these is my cabinet? The ones starting with CH are Christchurch presumably, but how do I narrow it down any more than that with converting the coordinate sand plugging them into Google Maps one at a time? Is there a naming convention that they follow?

There used to be a tool on the Chorus website but unfortunately they've replaced it with the significantly less useful UFB service map. Luckily the old tool is still available here: http://bcc.telecomwholesale.co.nz/ (if it gives you a blank page with a link to the new map just enter the address manually in the browser).

Search for your address and then look at the cabinet names on the right. Find those names in the spreadsheet to get their map coordinates. If you like you can PM me your address and I'll track it down for you.

Brilliant, exactly what I needed. I'm bookmarking that!

240m according to Google Maps, assuming it follows the road.

Ok, going by the stats we've gathered in the first post 8db is about right.

The problem with that tool is that it's significantly out of date, it says broadband probably isn't even available at my address, however I get decent ADSL2 and now VDSL2 connections. My cabinet installed in like 2011 isn't on the map.

Out of date is better than not available at all, IMHO. As far I know there is no alternative short of building your own using the shape files and cabinet locations Chorus provides.

Was good for me to determine what my cabinet name was, and then the up-to-date spread sheet gave me the exact location. So it was very helpful for me as my cabinet obviously predates when they stopped updating it.

Interesting thing happened.

I had emailed Snap a few days ago about my latency getting worse, and I got a response back today:

"...it seems interleaving was switched automatically on based on the automated DLM that chorus uses to improve line quality. It may simply be an issue of this which we can turn off very easily"

That makes it sound that Snap can get Chorus to override DLM changes doesn't it?

I'm still going to redo the cabling before I get them to change anything, but I thought that was an interesting response as I thought we were at the mercy of DLM. Or maybe I'm just talking about stuff I don't properly understand?

Interesting situation going on here. Yesterday just after 12pm VDSL got switched on here. Synced with 7dB attenuation and no added latency, so I take this to mean DLM1.

Because it's kinda mesmerizing I watched the stats off and on during the afternoon, and noted that the CRC rate climbed gradually throughout the afternoon, until by dinner time it was up to 10 per minute.

Around dinner time I did what I'd been meaning to do for a while: rewired the cable from the master filter from connecting to a socket in the wallplate, to an RJ45 plug and whacked it straight into the back of the modem.

From that point on it synced at more or less the same numbers but the errors started climbing even faster. Just got home now from a day away, and CRC count is at 42 per minute. No resync though.


So, questions: is it worth me doing a reset and bumping the SNRM across a notch to stable, or should I wait and see if I get bumped down to DLM2 first?

Second question: if I messed up the polarity of the cable when I crimped on the plug, could that contribute to the error situation? I tried looking online for info, and just found conflicting info and a bunch of flame wars.

For me latency and jitter is way more important than throughput, as the most 'connection dependant' thing I do is video conference. I'd take half the throughput if it meant retaining zero added latency.

Cheers

Hi, all just got my new SNAP connection today. I thought that I was close to the cabinet but unfortunately I am 870m away. Here ar my stats, not good :(

Hi Woody! Yeah, your line is one of the worse off we've seen, but it's due to the distance factor, it's up to you if the extra price is worth the extra speed you get from ADSL.

on the upside, DLM-1, errors are great, you look like you will have some space to SNR tweak once your line settles..

ild still take that over adsl!

This, definitely this. A decent bump in Download, massive increase in upload and  plenty of room to SNR tweak with those errror rates. I'd take that over ADSL any day.

Yeh it is a bit gutting but the speed is way better that adsl especially upload, and I won't get shaped like crazy like I did with Slingshot. Was kind of funny when I canceled my account they were worried why I cancel then said "because you don't offer vdsl," and the guy just said yeah a lot of people doing the same thing.
