What is acSysTDMClockAutoFallBackEnable?

This OID enables or disables automatic fallback when the primary PSTN trunk clock source becomes unavailable. Engineers turn this on to ensure continuous operation even if the trunk used for clock synchronization fails. Enabling this (setting to 1) allows the system to switch to a secondary clock source automatically when the PSTN clock fails.
