    I've seen sync speeds of just over 30000kbps before on an iiNet DSLAM - customer was next door to the exchange

    I would LIKE NBN for home server and interconnecting other family remote connections into a larger network

    It's funny how the ITU specification of G.992.5 states that the maximum downstream rate is 24 Mbps.

    This thread reeks of bullshit. Either that or false reporting by dodgy CPEs.

    NBN is close to 4x the download speed and 40x the upload speed, and has the capacity to going to gigabit since the infrastructure will support it.


    You can keep copper then ill settle for fibre.

    Specification is just that, a spec to follow. It has to adhere to those specifications at minimum really. If the vendor can build something better, but still meets those specifications, why not do it?

    In any case, there is plenty of situations where line rates are higher than 24mbit in real world scenarios, so it is definitely not bullshit.

    No not really. That match-up worked for the chipset that was being used in those 7400's at the time, and the specific DSLAM we were using at the time. Different companies use different DSLAM's which interact with different modem chipsets differently. 7800/N no doubt uses a different chipset to the 7400's and thus may have different compatibility to the different vendors.

    If you are on a 'custom DLSAM' i.e. NOT a Telstra one (iiNet/Internode or TPG or similar), then do some research over at Whirlpool, users tend to sus out which chipsets work better with that companies vendor of choice, or their support desk might even have some suggestions. I've seen some 8mbit connections go upwards of 10mbit+ from just a change of modem.

    My gigabit sychronous fibre connection says you do... and the rest of Australia for that matter.

    (Sweden, unlimited ~$130/month).

    Give me a fundamental reason why someone privately would require such a connection.. blueray streaming is not available in this country. :thumbup:

    It's all about your patterns of usage.

    For instance, I wouldn't recommend my parents above the 25/5 speed for NBN.

    I myself would be going for the 100/40.

    I happen to have multiple devices, that, when running at their best, could all be quite bandwidth hungry. If I'm streaming a video to the lounge room, while the girlfriend is watching youtube or skyping in the other room, while i'm running a backup or downloading some files, I don't want any of them to suffer for the other task.

    Gigabit, though, is probably much more then a sane person could fill for personal,private use (not hosting home servers and the like for public access). Not that it wouldn't be nice :p

    Out of interest - Which PHYR chipset modem do you use? Billion? And which one?

    The upload speed is handy, backing up critical data onto cloud services and so on.

    Netflix via VPN is also very nice.

    I like to think of it as future-proofing. We don't need it now but we may make use of it later on. Building solutions designed for today's needs is narrow-minded.

    Personally though, I have no need for anything higher than ADSL2+, and that's with my own website hosted from home.

    I'd love to just one time when a tech calls me with his JDSU or Sunset connected to a port to try out the high speed profiles.

    Nonetheless I've had a 7800N connected to a port at work with a manually adjusted SNR target on a ADSL2+ standard profile to connect at about 26.5Mbps.
