What is acSysTDMClockAutoFallBackRevertingEnable?

This OID controls whether the system automatically reverts to the original primary clock source once it recovers from a failure. Operators enable this to ensure long-term stability by always preferring the primary clock when it becomes available again. Setting this to 1 means the system will switch back to the primary PSTN clock automatically when it recovers, rather than staying on the backup.
