7.6 RadioBlade Alarm Handling
The iDEN RadioBlades track various faults and report those to the RadioBlade controller. These
faults are monitored and if the rate at which these faults occur surpasses a threshold, the blade is
locked. The RB will generate these faults as the result of normal actions such as re-syncing the
blade, locking and unlocking the RB and locking and unlocking the BR. For these reasons, only if
the blade continues to generate these faults under normal operating circumstances is an alarm
generated.
The RadioBlade tracks the following faults:
i. PLL1 Errors – The Phase Lock Loop #1 went out of lock.
ii. PLL2 Errors – The Phase Lock Loop #2 went out of lock.
iii. PLL3 Errors – The Phase Lock Loop #3 went out of lock.
iv. Tx Underrun – RB did not receive a packet in time to transmit.
v. Tx Overflow – RB received too many packets to transmit.
vi. Rx OverFlow – Sample buffer overflowed.
vii. Slot mismatch – Received packets were not consecutive.
viii. CRC errors – Received Ethernet packets had CRC errors.
If a RadioBlade generates enough errors such that it crosses the Bounce and Duration threshold
for that particular error, an alarm will be generated. This alarm will also cause the RadioBlade
Locking Policy to lock that RadioBlade. The following table lists the number of faults and the fault
period for an alarm to be generated.
Alarm Bounce Threshold (counts) Duration Threshold (minutes)
PLL 1 75 12
PLL 2 75 12
