Parameter
Description
Quality Level Mode
Enabled
: the user can set the equipment synchronization to take into account the SSM synchronization
sources (Synchronization Status Message)
Disabled
: the device ignores the SSM synchronization source.
Reversibility level
mode
Enabled:
the status machine of the equipment only considers for synchronization source, a source that
does not show timing flaws and where the Reversibility Time has expired. If the quality/priority of this
source (depending on the current configuration of the Quality Level Mode) is higher than the current
source, the equipment will use this quality/priority source. Otherwise the source is not changed.
Disabled:
a source that has been previously considered invalid will only be used for synchronization, if
the current source fails and if there is no other source with a higher quality/priority
