The NBN installer came yesterday and put in their gear. A new plate in the wall? Alongside your other HFC connection? Right now I'm still on the ADSL I've always had. No indication of interferences. ADSL uses Telstra's ageing copper. HFC is a completely separate network. Both should never have been used in a new National Broadband Network (NBN). Now we have Malcolm's Terrible Mess (MTM). You are lucky you can co-exist with ADSL. It's the unfortunate users who have been shafted with FTTN that are having issues; they get cut off from ADSL immediately, and if the FTTN doesn't work... weeks of no internet or phone. -andyf PS.

The RSP cannot make it any faster. They must share the limited BW between themselves. 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. I fully understand what you were saying. RSP's need to find the balance between the amount of CVC they purchase and the amount of bandwidth they are selling. (They have to do this 141 times if they want to provide nation-wide.) *My* point is that bandwidth to a node (FTTN) is limited. 1000Mbps. Divide that by 384 users (node capacity). You get 2.6Mbps per user. RSP's can't make it go any faster no matter how much CVC they buy. 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 That article is old - before the RSPs knew what to expect. Most now have a better idea, and increase their CVC appropriately. 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. Again, before RSPs knew what to expect. At least your FTTP is limited to only 2600Mbps / 32 users 81Mbps. See why I'm envious? :) -andyf PS. I'm on Fixed Wireless. There are probably close to 200 users on my tower. Backhaul from the towers is a measly 100Mbps. ___ Link mailing list Link@mailman.anu.edu.au http://mailman.anu.edu.au/mailman/listinfo/link
