Your Vigor 2700 or 2800 uses an ADSL2/2+ modem chipset capable of communication at up to 24Mbps over a standard copper phone line. At the telephone exchange your phone line is connected to a DSLAM; which is effectively a group of ADSL modems in one box. With ADSL 1, Telstra provided all the DSLAMs and set them all the same configuration - so DrayTek were able to provide one firmware suitable for all ADSL1 users in Australia.

If you are on a 'normal' (ADSL1) internet connection, you are almost certainly connected to one of Telstra's DSLAMs at the telephone exchange, no matter which ISP you use. DrayTek have provided "Standard ADSL1 for Australia" firmware which is tuned to Telstra's ADSL1 standard configuration; and can be downloaded from the Downloads section of our website.

Since ADSL2/2+ is backward compatible with ADSL1, all the firmware should work on an ADSL1 phone line; and you may find one of the other firmware gives a more stable connection, depending on the distance and quality of your phone line, etc. You are welcome to try any or all of the firmware files to find the best for your individual environment.

If you are on an ADSL2 internet connection or connected to your ISP's ADSL2 DSLAM, your phone line will be connected at the telephone exchange to a DSLAM provided by the ISP. There are several ISPs currently offering ADSL2/2+ and using different DSLAM hardware and configuration parameters.

Unfortunately the high speed of ADSL2/2+ makes it more susceptable to distance from the telephone exchange, number of joints in the cable, and quality of your phone line, etc. Put these issues together and it becomes obvious that no single firmware file can be optimised for all the combinations available in Australia.

Rather than ask customers to adjust configuration parameters which most users would struggle to understand; DrayTek have instead made available a number of pre-tuned ADSL configurations. At the time of writing, DrayTek's international website offers 13 variations of Vigor 2800 firmware v2.7.1 which are tweaked for local conditions (particularly differences in tuning of the ADSL parameters).

Since there is no one standard ADSL2/2+ configuration in Australia, we have made all the AnnexA versions available through our Downloads pages ... so that customers can select the best for their combination of ISP and line.
