8.5 RadioBlade Transceiver Alarm Handling

The iDEN RadioBlade transceivers cabinet various faults and reports to the

RadioBlade controller. These faults are monitored, and if the rate at which these

faults occur surpasses a threshold, the RadioBlade transceiver (blade) is locked. The

blade will generate these faults as the result of normal actions such as re-syncing the

blade, locking and unlocking the blade 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 transceiver faults are listed in Table 8.9.

Table 8.9 Faults by the Transceiver

If a RadioBlade transceiver 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

transceiver. Table 8.10 lists the fault count and fault period for an alarm to be

generated.

Fault Description

PLL1 Errors The Phase Lock Loop #1 went out of lock.

PLL2 Errors The Phase Lock Loop #2 went out of lock.

PLL3 Errors The Phase Lock Loop #3 went out of lock.

Tx Underrun RadioBlade transceiver did not receive a packet in time to transmit.

Tx Overflow RadioBlade transceiver received too many packets to transmit.

Rx OverFlow Sample buffer overflowed.

Slot mismatch Received packets were not consecutive.

CRC errors Received Ethernet packets had CRC errors.
