31 Use the Copy Memory command to copy the database from volatile to
nonvolatile memory within the TimeSource 3500.
CPY-MEM:[tid]:TS3500:<ctag>::WKG,,AUX:DATA;
Note:
Although the database is automatically copied to nonvolatile memory
once per hour, it is recommended that the Copy Memory command be
executed each time the database is changed.
32 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 3500 develops and sends timing within the PRS
specification during normal operation and during any event (other than
settling period) or minor alarm, but not during a major or critical alarm.
