bisr: I can peak at 30mbits (not bytes, I get 2.2 MegaBytes) per second on my ADSL 2 connection. Seen it with my own two eyes in dd-wrt. And I live near Orewa.


It's simply not possible.

ADSL2+ can offer a maximum theoretical downstream throughput of 24Mbps before all overheads are taken into effect. This means you're typically limited to around 20 - Mbps depending on noise margin on a perfect 24Mbps sync rate (virtually impossible in the real world unless you're connected to a DSLAM), or slightly less if Annex M is used.




Okay I accept that it's possible with the signal delay in measuring the packets coming in where dd-wrt reads a blockage which creates excess flow as a spike in the throughput would result in my misinterpreting the data. Also I think in my brain I have calculated the ratio between bits and bytes backwards and this has given me 'tinted glasses' because when I go back to dd-wrt Iright now it's 18-19 Mbps and 2.2MBps and I am getting it right now as I type this.

TF2 Heavy "Is not possible!"


EDIT: Wait no, that's only ~18mbit/s as you said, which ADSL2 can do. But that's no where near 30mbit/s

'tis, possible, using jdownloader.

EDIT: I was being retarded about the ratio between bits and bytes. See above. :-)

bisr: Given that you can't even get residential Fibre in Auckland CBD and it won't be there for two years, I feel pretty safe in saying that Fibre is not a reality for residential customers in New Zealand yet.


must....resist.....the....bait


Sorry it's not baiting, it's just that I can't get it and neither can my clients. That equals it is not a reality. Just because it's in Ponsonby and Grey Lynn where it has been tested since 2010 does not mean that it is exists as an option for the remaining 90%+ of Aucklanders. And if it isn't a reality for the drastically most populous place in the country... therefore...

The fact that the OP is in the anomalous situation of having fibre as the only option does not adjust my observation.

That said, this isn't really the place for it and if I say anymore I will be derailing I think.... It was just an offhand comment I was making about us talking about fibre. That happens to be a reasonable one.


Auckland CBD is probably going to be one of the more difficult parts considering the work required to dig up streets and the like. I'm not sure how they will deal with multi tenanted (IE ALL) of the city. run a duct into the basement with a single prism for all GPON customers and p2p for others?



Also in regards to unlimited broadband for $60, it's not really unlimited. The cost price for maybe even 1mbit of transit bandwidth for the ISP is probably more than the monthly cost of that plan and that isn't including any tail, handover or backhaul costs.


And lastly I still don't think FTTH was a wise investment given the time. With so much invested in cabinetization, VDSL would have been a better alternative at a much cheaper price at least for the next 10 years. Sure - improving accessibility in commercial/business areas may really help the economy - not watching some cool internet tv on your couch.
