Apparently our Pakuranga exchange is ADSL2+ live today. Those of you with ADSL2+ capable modems are you getting a faster connect speed? I'm not sure if this is a closed Pilot or open to others on the exchange with ADSL2+ capable modems, only one way to find out..

My opinions and ideas expressed in posts are solely my own and do not reflect the views of my employer in any way..

Do you have an ADSL2+ modem? have you noticed any increase in speed when testing at speedtest.net?

All I can say is c'mon TAK3.. I'd love to get this ADSL2+ router going to potential :p

Many modems will have an option to force-select ADSL2 negotiation, you could see if you can turn that on and see if it connects. if so, you're in business, if not then your exchange presumably isn't one that's configured for it.

AFAIK ADSL maxes out at Xtras 7Mbps, hence why that's their "as fast as your line allows" (*cough*) limit, ADSL2+ expands this speed up to about 24Mbps, but if it's still capped at 7Mbps for now, then I doubt you'll see any real difference. People in poor signal errors should get a benefit from ADSL2+'s improved efficiency, but if you're already in a good signal area, I wouldn't expect too much until they open things up more on an international basis. And you still only get 1Mbps upstream.

Just noticed a Netgear DG834 firmware update that adds just this selection option, so I'll update it, force ADSL2+ and see if it improves the connection speed from the current 3800Kbps...

*Edit*

Forced an ADSL2+ connect and it connected ok, as I'm pretty sure it's backwardly compatible with ADSL1, that doesn't really mean much as the router isn't actually telling me which protocol it's connected with, but regardless of that, I'm still talking to the net at 3.8Mbit, so I'm guessing the local exchange is still either ADSL1, or I'm just not getting any benefit.

Maybe someone with a more verbose router can provide some more substantial reports of any benefits.

Telecom "Whole Story":

The ADSL2+ roll-out kicks off this month with the Pakuranga exchange in Auckland the first to have new customers connected.

Khandallah in Wellington will follow shortly after as we work to roll out ADSL2+ capability to exchanges in Auckland, Wellington, Hamilton, Christchurch and Dunedin throughout this year. Telecom retail and wholesale customers will gain ADSL2+ capability at the same time.

Wholesale customers are being consulted on a wide range of issues including the roll out schedule and preparations for future services that take advantage of ADSL2+ capability (see story on consultation above).

ADSL2+ is an enhancement to the underlying network technology between the DSLAM and the end-user. End-users’ experience will be affected by the same variables that broadband has currently – such as distance from the exchange, home
wiring and copper quality.

End-users presently on full speed (unconstrained) connections with ADSL2+ capable modems, and who are within two kilometres of an exchange or cabinet, may experience faster download speeds once the bulk migration to the ADSL2+ DSLAMs is completed.

Over time new services will be developed on ADSL2+, following customer consultation.

Beyond 2007, ADSL2+ capability will be progressively deployed to other towns and cities where there is significant demand for the new services or as existing ADSL1 equipment is replaced. Legacy ADSL1 DSLAMs with an economic life will be redeployed to meet demand for broadband elsewhere in New Zealand.

As far as I understand ADSL2+ will only be available to new customers signing up on the Pakuranga exchange, and existing customers will be migrated in the near future. So it means you are unlikely to notice any difference, for now...

Currently when dealing with port speeds, its as fast as the line and standard allow. You won't get much higher than 7mbps (perhaps 7.6mbps) on a DSL exchange. It is highly unlikely that once ADSL2 is enabled on the DSLAM that a connection speed limit of 7mbps would be applied.
Lower speeds despite the higher port speeds generally other factors, for instance - network congestion, backhauls etc.. .

Currently only one exchange has this, and as pointed out - not everyone on that exchange will get ADSL2 straight away. There will no doubt be more information coming to light as it slowly gets rolled out and people with DSL2 ready modems in place, people will notice sooner or later...

cranz: Telecom "Whole Story":

I followed the link to a pdf with a heading "Continuing the momentum" and just had to laugh. It is of course possible to have a momentum of zero.

Or perhaps they mean angular momentum, and it's all spin.
