ADSL1 is a technology, having a max of 8mbit.
ADSL2+ is a technology, having a max of (legally) 20mbit and (actually) 32mbit
if you cant get ADSL2 its cause the DSLAM hasnt been upgraded. i dont think there is any telstra exchange that cant do ADSL2+ and hasnt been for years.
chances are, if your not getting speeds above 8mbit, its cause your too far from the exchange.
haha, thats one of the oldest jokes in the industry. we used it last week talking about a project
