Configuring rate adaptation
Automatic-at-startup
This rate adaptation setting selects a rate during the training (startup) process. The line
attempts to initialize at the maximum specified bit rate, and target noise margin. If the line
fails to achieve the maximum bit rate in either direction, it attempts to initialize at a lower
rate until it reaches the minimum specified bit rate. If the line is unable to initialize at the
minimum specified bit rate, then it does not start and sends a message that the requested
bit rate was too high.
Operator-controlled
This rate adaptation setting starts the line at a specific planned bit rate with an acceptable
target noise margin and maintains that rate. The line does not use a higher bit rate, even if
it can support one.
