peza: Congratulations Orcon...

3. It is also a myth that VDSL2 dies or is only useful up to 1.2km~1.5km, I think you were thinking of VDSL1.
The DSL forum has some great tutorials on DSL, and specifically VDSL2
http://www.dslforum.org/learndsl/ppt/VDSL2_Tutorial-2005.ppt



I guess this comment is aimed at me. We'll have to agree to disagree.

But I sat in those wonderful workshops which said GPRS would run at 174kbps (neglecting to mention this was with no error correction, and the device transmitting at an illegal power level), and the other's that said ADSL2+ was 24mbps down (1km from the exchange).

Plus I've seen firsthand what VDSL2 in NZ looks like when it's running. And distance has a huge impact.

It looks like I have raised more questions than answers - wonderful medium Geekzone Cool
I do agree with you Antoniask, that distance has an impact on VDSL2, and the fall rate in the 1km~2km is much higher than ADSL2+.  It is the intentionothat VDSL2 acts (behaves) like ADSL2+ at greater distances....I would love to hear if anyone out there is using a ADSL2+ modem on a VDSL2 line...maybe the Inquistor ? It is my understanding that Belgacom and Germany are deploying large scale VDSL2...any feedback appreciated.
As Antoniosk there are claims made about bit rates - "GPRS would run at 174kbps", I would also like to see the first HSDPA system running at 14.4Mbps (not in a lab).

I am surprised by DTAG problems, once again a nice link to a whitepaper from "Aware" about VDSL2/ADSL2+, see page 8, this also talks about the VDSL2 profile deployment of Deutsche Telekom - with the profile they are using a range is expected of 3kft (1000m). http://www.ictregulationtoolkit.org/en/Document.2957.aspx
I would like to hear more about the chipset interworking and features...Ikanos, Broadcom, and Infineon seem to be the main players.
Infineon Technologies, a vendor of Communication ICs, has announced that T-Com, the Fixed Network business unit of Deutsche Telekom AG will base the rollout of its new hyper-speed VDSL2 network entirely on broadband access systems powered by Infineon’s VINAX chip-set.
It looks like Ericsson are planning to use Broadcom, and most Asian players are looking at Ikanos

The DTAG pricing table that I listed was only indicative purposes (thanks Inquistor) for anyone out there interested in pricing in Germany there are many operators 1und1 (1&1), Arcor/Vodafone, all moving into the VDSL2 space. And if Inquistor gets a chance to go to Berlin BBWF in October http://www.iec.org/events/2007/bbwf/conference/workshop_6.html this would be a interesting workshop to attend, and raise your questions.

An excellent point raise by Inquistor "I wonder what people expect from VDSL2+."  I ask myself the same question with FTTH from my friends in Asia - who have 100Mbit/s FTTH (actual throughput tested - 28Mbit/s within Korea, 2.6Mbit/s from Microsoft in USA), but if they would price it at $50 USD a month I would get it also - so it's more about market perception, and the Smith & Joneses (you know what the neighbours have !)
At the bottom of this link
http://www.computerbild.de/artikel/cb-Heft-Service-zum-Heft-Der-grosse-DSL-Geschwindigkeitstest_1184340.html#
are the download test results from 370k hits, with bit rate vs 1Mbit/s, 2Mbit/s and 6Mbit/s ... if anyone has better results much appreciated (in English please).

And a final comment to Inquistor "it will take years until backbones have been upgraded to the bandwidths VDSL users may require" sure this is true, I believe the Orcon's and CallPlus, iiNETs, Internodes who a now nimble and smaller than the TNZ, Telstra's and don't have the legacy to worry about will be the inovators of the new era of true broadband.
Now that we have five lane drive way, and the streets are still dirt tracks, we have a long way to go.  Considering what has been done over the last five years, we live in an exciting new world !
