This clear code is mainly mapped from external clear code. Please check document “Mapping of External Data”3rd March 2009 at 09:35 #56062RAYGuest
i have checked the document “Mapping of External Data”and found
0x66/102 recvry_on_timer_expiry –> 0x0822 n_recovery_timer_expiry
i understand its a external code 66 but what to check after that..

Now check from additional field from what PRB it comes. Start failed call observation on clear code 822 and you will get all information.4th March 2009 at 09:56 #56064RAYGuest

i have identified the POI and point code..can i do some modification that would reduce 822.9th March 2009 at 18:02 #56069MikeGuest
What is POI? Before do modification it is required to understand why CC822 is coming.13th March 2009 at 14:05 #56070RAYGuest
