"CM-MODE testing" only has 1 action:
action modulation
so the only thing it will do is change modulation
if you add channel-width, that moves from one logical to the other. Obviously each logical-channel needs a separate channel-width. i.e. logical-channel 0 has channel-width 6.4 MHz and logical-channel 1 has channel-width of 1.6 MHz
the order in which you add them to action command determines which action it takes first.
so you probably want a spectrum rule that looks something like this:

How is the UPS interface configuration in "CM-MODE testing" so that the CMs with problems switch to logical-channel 1 ? Thanks kwesibrunee!!
"CM-MODE testing" only has 1 action:
action modulation
so the only thing it will do is change modulation
if you add channel-width, that moves from one logical to the other. Obviously each logical-channel needs a separate channel-width. i.e. logical-channel 0 has channel-width 6.4 MHz and logical-channel 1 has channel-width of 1.6 MHz
the order in which you add them to action command determines which action it takes first.
so you probably want a spectrum rule that looks something like this:

kwesibrunee , What is the recommended minislot when I have both logical channels enabled with different bandwidths?
example:
logical-channel 0 minislot 2 // BW 6.4
logical-channel 1 minislot 16 // BW 1.6
Thanks.
