In the time it takes to have a shower, our broadband connection has been swapped over and we now have ADSL2+!

ADSL1 (Before, Telstra DSLAM) | | Upstream | Downstream | | — | — | — | | SNR Margin | 24.5 dB | 24 dB | | Line Attenuation | 34.5 dB | 20.0 dB | | Speed | 256,000 | 1,536,000 |

ADSL2+ (After, Agile DSLAM) | | Upstream | Downstream | | — | — | — | | SNR Margin | 9.0 dB | 9.0 dB | | Line Attenuation | 38.5 dB | 21.0 dB | | Speed | 942,600 | 11,467,480 |

Internode have the facility to customise the ADSL2+ profile, so tweaking that may improve things slightly. I’ve also got a Central Splitter that I plan to install as part of our house extensions so that should help things slightly too. But you can’t complain about a 10x improvement!
