CDMA Frequency Transient Event

The CDMA receiver performs a complete update of the current
time (clock bias) every 2 seconds. The TimeSource 2700 compares
the current frequency estimate of the corrected local oscillator,
with respect to CDMA, and declares a CDMA Frequency Event, if
the magnitude of the offset is greater than the threshold of
0.02 ppm.
Maintenance action required - None.

CDMA Frequency Event

The CDMA Frequency Transient Event data is processed through
a leaky-bucket alarm manager to control escalation to an event.
CDMA Clock Bias Transient Events and Time Accuracy Transient
Events are included in this general frequency event category. A
frequency event represents an error in the CDMA receiver output
state, or a failed oscillator. The nominal time to escalate to an
event condition is 2 minutes. The maximum time to retire an event
is 5 minutes.
Maintenance action required - None.

CDMA Frequency Alarm

The CDMA Frequency Event data is processed through a leaky-
bucket alarm manager, to control escalation to an alarm.
Maintenance action required - If a PLL alarm is also present,
replace the shelf.
