Hi there,

I was just wondering the difference in speeds for VDSL lines.

http://speedtest.net

Please post your results and the ISP you are with.

NOTE: This is only for VDSL customers thanks.

Might be a better idea if they posted modem sync rate

They can post that additionally if they know how, but I am more interested in what sort of uplink it can pump.

I'll be interested to see if many people can beat this:

10357 kbps /69993 kbps

I am with Unleash and using a Zyxel Modem.

I regularly sustain download rates of over 7.4MB/s

I am on Snap's VDSL service.

Local download speeds are not so flash for some reason.

Can upload data at about 1100KB/s

Speeds are bit better to Telecom speedtest

Napster, interested to know what your modem stats are, including the line attenuation.

Hmmm.. I too am on Snap VDSL. But as of now (7pm), I am only hitting 20/8Mbps in both a normal speedtest and with Telecoms speedtest. That's the first time I have noticed that much of a drop in speed.

My line stats are 46000/10000. Attenuation: 4dB down/0 dB up.

Normally I can download at 3.5MB/s and upload at 1.1MB/s.

Well worth the extra $50 just for the upload IMO.

====EDIT====
Haha, well that was stupid of me... I forgot I was using wireless on my MBP, so I logged on to my hardwired server and I am getting 45Mbps down.

To you guys that have VDSL would you ever go back to ADSL2? Was it worth getting?

My wife and I have just bought a house in tropical Tawa, and it is too far from the exchange to get VDSL... so when we move I will lose it. I do have other options though.

I wonder how Snap deal with that considering I am on a fixed term VDSL plan? I still plan on being with them BTW.

It's going to depend entirely what the connection is for.

ADSL2+ has the ability to have interleaving set to low or off, VDSL2+ is currently fixed on high adding 16ms of latency to a connection. With EUBA Ethernet connections you can do lots of cool things over ADSL2+ that can't be done over UBA/UBS connections such as bonding etc.

The biggest advantage of VDSL2+ is primararily the much better upstream.

Not true on the interleaving front for VDSL.
While it's correct you CAN select the interleaving level on EUBA (ADSL2+) services, it's not selectable when provisioning WVS (VDSL2) and defaults to High.

However, Dynamic Line Management (DLM) will monitor your line proactively and alter your VDSL profile accordingly.
DLM will automagically upgrade/downgrade your profile (i.e.: 8b/17a) and interleaving level.

We have many clients on VDSL who have interleaving on fast (effectively 0ms) - it's all dependent on how good your line is, and how close you are to the exchange.

We are considering a new house, but a prerequisite would be VDSL or UFB Availability on day1.

Heh I could care LESS about the upload, if it was 2Mbit, I'd be happy. I LOVE the 7MB/s I download at.

Except DLM is not available on all cabinets and exchanges, so is currently only available to a small number of VDSL2 installs. All requests for changes to profile or attenuation for VDSL2 are currently rejected by Chorus.

Correct - profile and interleaving are not selectable, nor changeable by request on a WVS service (except in cases it resolves a fault - typically changing interleaving to high from fast).

By far the most common ISAMS/DSLAMs used for WVS are the Alcatel 7302's (and for EUBA too ... they're the preferred ISAM/DSLAM used in the whisper cabinets) - which support DLM inter feature set.
In fact, I'm not sure I've ever seen a WVS service thats not on one now I think about it?
