A note on modem codes
The firmware labelled 'BT' is the recommended modem code for UK lines.
Other modem codes are available, some are newer and others older than the 'BT' 1232305 modem code. The digits indicate the version number, with a higher number being a later revision. Older modem codes can be considered more conservative, and might not include support for supplementary DSL standards or may have parameter options disabled. New modem codes incorporate improvements and support for later standards and may have options enabled.
