TRADE SECRET INFORMATION 
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. 
 
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 29 lists 
the fault count and fault period for an alarm to be generated.

In addition to the above-mentioned errors, if the system loses communication with a 
RadioBlade transceiver or is unable to read the EEPROM from the blade, then that blade 
is put into an error state and if a standby blade is available it will switch over 
automatically. 
7.6.1  RadioBlade Locking Policy 
The RadioBlade locking policy defines the actions taken by the system when a 
determination is made that a RadioBlade transceiver should no longer be allowed to 
remain active. This could be the result of an alarm, insertion, removal or intervention (the 
user specifically locking the RadioBlade transceiver). 
In general, the policy is that if a blade is taken out of service and a standby RadioBlade 
transceiver is available, then the standby RadioBlade transceiver will go into service. If no 
standby RadioBlade transceiver is available then the associated BR(s) will be locked. 
(For the Multi-Channel RadioBlade transceiver, the locking event locks all carriers.) 
The RadioBlade locking policy is enabled by default and in effect at all times.  
7.6.1.1 Standby 
Blade 
A Standby Blade is an extra RadioBlade transceiver that is installed in the system but 
does not have a configured BR with which to register. To setup Standby Blades, make 
sure that there are more RadioBlade transceivers for each RBS Group than Base Radios 
configured in the iDEN configuration page.
