Function
A change in at least one of the M4 Bits
will be passed via MON-2 only after
valid triple last look
A change in at least one of the M4 Bits
will be passed via MON-2 only if the
CRC is valid for the last two
superframes, not including the current
one.
A change in at least one of the M4 Bits
will be passed via MON-2 only after
valid triple last look, and if the CRC is
valid for the last two superframes, not
including the current one
Every change in at least one of the M4
Bits will be passed via MON-2
A change in at least one of the
Additional Overhead Bits will be
passed via MON-2 only after valid
triple last look.
