A.7.2.6 Redundant Mute Mode
The redundant mute mode determines how the backup unit handles the mute state during a
redundant switchover condition. If the redundant mute mode is ON then the backup unit’s mute
state will be the same as the primary unit that it is backing up. Otherwise, if the redundant mute
mode is off the backup unit will unmute its output any time a redundant switchover occurs.
The default redundant mute mode state is OFF (backup unit’s output automatically unmutes
when a redundant switchover occurs).
