Notes:
Audio silence is deemed to refer to embedder audio signals only, unless that embedder is
OFF - in which case de-embedder signals are tested for silence.
If silence is sustained for more than the silence detect delay the assigned GPO will be
asserted low as an alarm when ‘flag’ is selected.
If an ‘input missing’ flag is effectively turned off by the ‘inmsk’ or ‘rfmsk’ setting it will
also be ignored in the ‘Auto’ menu (all menu levers ON/UP, SEL=0) as an error
condition.
