CLI Command Description
acm
SYNTAX
acm enable <on | off>
acm mod <modulation> enable <on | off>
acm mod <modulation> mse_de <value>
acm mod <modulation> mse_im <value>
DEFAULT VALUE
acm enable: Off
acm mod <modulation> enable: on
acm_mod <modulation> mse_de: see table below
acm_mod <modulation> mse_im: see table below
DESCRIPTION
acm is used to turn on the adaptive modulation feature.
When enabled, the current speed may shift to different
profile (modulation based) based on the current MSE
value. And predefined MSE degrade and imrove
thresholds
ACM is not symmetric and each end can have different
profiles at a given time depending upon the MSE values
on each end.
acm mod is used to enable/disable certain profiles. It
could also be used for changing the value for mse
degrade table or mse improve. When the threshold of the
MSE reach certain value from the table, the profile will
change thus, the modulation for rx will be changed.
Note: This feature is not supported in current release
