Line Rate Mode
Possible Settings: Hunt, AutoRate, Fixed
Default Setting: AutoRate
Specifies the mode to be used for rate selection.

until training is successful or the unit is reset.
AutoRate – The unit automatically detects the line rate from the network interface.
Fixed – The unit uses the line rate specified by DSL Line Rate.
