This value configures how a Symmetricom timing output port behaves specifically while the system clock is in its warm-up state, choosing between on(2), squelch(1), or AIS(3) alarm-indication-signal output, as one of four per-clock-state settings in this output-generation table. A telecom engineer sets this so downstream equipment doesn't receive a misleading timing signal while the clock reference hasn't stabilized yet. For example, setting outGenConfigWarmup to squelch(1) on a given port would silence its E1/T1 output entirely until the clock leaves warm-up.
