I believe you should read this:
ADSL2+ is the next generation of ADSL broadband with download speeds typically much faster than regular ADSL. Regular ADSL broadband has download speeds between 256kbps and a maximum theoretical speed of 8Mbps. ADSL2+ will allow you to enjoy large file downloads, graphic intensive online gaming, online streaming TV and radio, VoIP phone service as well as new applications and services currently being developed for super speed connections.
To achieve optimal TPG ADSL2+ speeds, customers must use an ADSL2+ capable modem and have filters installed on all telephone outlets. 20%, 50%, 70% of these ADSL2+ customers are achieving speeds of approximately 20Mbps, 15Mbps and 10Mbps respectively. Actual speeds achieved will vary due to a number of factors including distance from the local telephone exchange, network configuration and traffic, the quality of the customer’s copper phone line, EMI, cabling and equipment.
Regarding Dope14, I wonder how he got a speed of +27Mbps even thought that DSLAM used can provide a maximum speed of 25 Mbps at a distance of 300 meters from the CO.
