34 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 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. In roof antenna installations, the nominal time to reach normal operation
(output a PRS signal) is 20 min. If normal operation 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. In window or wall antenna installations, the nominal time to reach normal
operation (output a PRS signal) is variable, depending on the view of the sky and
the satellite positions at the time of power-up, and may take up to several hours.
If normal operation is not reached, refer to the Troubleshooting chapter.
4. The TimeSource 3600 develops and sends timing within the PRS specification
during normal operation and during any event or minor alarm, but not during a
major or critical alarm.
