Perhaps what I meant wasn't clear. I meant that even if NBN Co. supplies sufficient bandwidth to a particular node, an ISP's customers still won't get the paid-for speed if the ISP chooses to have contention ratios that are too high. That is, if they fail to pay for sufficient CVC capacity from NBN Co. and/or sufficient backhaul from an upstream carrier. There have previously been cases of people blaming FTTN for slow speeds, when the cause was actually the ISP's contention ratio. See, as one example, the case in this article: The NBN: Truth in the battle of FTTN and avoiding new FUD http://www.pcauthority.com.au/Feature/415565,the-nbn-truth-in-the-battle-of -fttn-and-avoiding-new-fud.aspx (I share the above writer's view to the effect that blaming NBNCo. for things that are not its fault "threatens to derail a lot of the good arguments that are being raised about the MTM" and wastes the time of Senate Committees etc which would be better spent on things that are NBNCo's and/or the gov's fault.) > Do you need a link to NBN Design documents that show how it was > severely hobbled by the honorable (<spit, cough, choke>) current > PM turdBull? > > I envy your FTTP connection, as it should've been for 93% of > Australia. FTTP speeds will also be slow if an ISP's contention ratio is too high. There've also been complaints about that since long before FTTN (nodes) existed.
