Yeh, I know... We should be moaning about drops in speed (as I have done in the past!), but the other day I did a speed test and my speeds have actually shot up on my VDSL connection. Not that I'm complaining mind, but the thing that confuses me is that my upload speed is now hovering at 27Mb/s, when I thought it should be maxed out at just a tad under 10Mb/s (which is what it was for me).

So, my normal speeds before this upswing was 50Mb/s down & 9.7Mb/s up.

I now get this:

Speed Test

Say, what?

I know Chorus have been in the area fiddling with stuff, but can't explain the upload speed? Been like this for a couple of days now.

Sort yourself out, Bigpipe. Can't be doing with these increases in speed.

Chorus are in the process of changing the VDSL band profile (997 to 998) used on their equipment. Would explain why your speeds have increased. :)

I worry what the change is going to do to my line, but awesome to see it has improved yours!

Chorus are currently making changes to their VDSL coverage and speed (specifically band plan change from 997 to 998). For a lot of people this means better upstream speeds due to the removal of the 10Mbps upstream cap.

They're trialling it in a few cabinets round the country; looks like you happen to be one of the lucky first :)

I didn't realise they would go up that much - makes things a little interesting when many of the UFB plans have upload at 10Mbps (do they still do 30/10? ) or 20Mbps... I wonder if this will confuse the issue more with many punters on whether upgrading to UFB is worth it.

The majority of punters have no idea what upstream is. As long as the big number is bigger.

My speeds went up as well, 30/10 to 55/10

I think a lot of people will still upgrade to UFB given the price point between the two. VDSL will still remain a more expensive product at a wholesale level, therefore an RSP level, and if I can get 100/30 for $80 or VDSL where I can potentially get 70/30 for $90, why wouldn't I go for UFB?

Thanks for the replies, peeps. Starting to make sense... Didn't realise they were moving to the 998 VDSL band.

I've just been reading about this upgrade to the 998 band just now to get some more info, and I came across this little snippet:

"The 998 VDSL band plan is more asymmetric, meaning higher download speeds (at the expense of lower upload speeds) compared to speed achieved under the 997 band plans." - http://www.tcf.org.nz/content/576773bf-4406-4a4f-8796-f217148d3201.html

Now, I'm doubly confused :)

998 moves the upload/download frequencies compared to 997. It allocates more of the lower frequency upstream band to download. For good lines this won't matter, as the upload was capped at 10Mbps artificially. I worry though that on poor lines removing the available downstream frequency will reduce upload speeds. Remains to be seen at this stage.

You should post your findings in the big VDSL thread, I'm sure people would be interested to see. In particular, if your modem supports it you should post the frequency allocation graph for your line.

I am on 34/10.

I'll be super excited if I get above 40 download!

Thanks. That makes sense now. I'm actually right across the street from our cabinet.

Keen to see what happens if they change it on my cabinet.... currently sitting on 40/10. Bit more upstream would be nice, will help with Plex :-p

do you have a comparison of the modem stats before and after?

and did the modem disconnect and reconnect prior to your change?

Yup, that makes sense, assuming UFB plans are going up to 100/30 from 100/20

Has anyone seen the test results, particularly for the longer loop lengths. Is there a chance this change will increase the range for VDSL from the exchange/cabinet?
