Procedure F. Power-Up (continued)
Step
33 When the GPS signals have been acquired and the outputs are stable enough to output a
signal, the TimeSource enters a settling period. During the settling period, the following
conditions exist:
• Status GPS lamp is green
• Status SYS lamp is green
• Any Span or Remote Oscillator lamp is green when its input is connected, entered,
contains valid framing, and is usable for ensembling.
• All outputs are functioning according to specifications or in a slightly degraded mode.
• A TL1 autonomous "settling period" event message exists.
Notes:
1. The nominal time to reach the beginning of the settling period is 20 min. If this state has not
been reached after 40 min., refer to the Troubleshooting chapter.
2. The settling period is the condition where this clock is beyond the warm-up state but not
yet in steady state operation. Steady state operation is indicated by the clearing of the
"settling period" event.
3. The TimeSource 3000 develops and sends timing within the PRS specification during
steady state operation and during any event (other than settling period) or minor alarm,
but not during a major or critical alarm.
