This value configures how a Symmetricom timing output port behaves while the system clock is in free-run state (running on its own internal oscillator without an external reference), choosing on(2), squelch(1), or AIS(3), as one of four clock-state-specific settings in this output-generation table. A telecom engineer sets this to control whether downstream devices keep receiving a (now less accurate) timing signal or get an alarm indication during free-run. For example, setting outGenConfigFreerun to ais(3) would cause the port to emit an AIS alarm signal to alert downstream equipment that timing quality has degraded.
