- RNC Important Alarms:- Alarm type Alarm severity Alarm name RNC10 RNC20 RNC30 RNC40 Comments Fault Warning Cell Congested 648 137 404 170 This alarm is reported when the RNC detects the cell in congestion status according to the specified criterion. This alarm can be cleared when the cell is no longer congested, or the relative common measurement is rebuilt, or the cell is removed/deactivated Event CN Originated Reset Resource 4 15 6 2 Cause: RNC receives the RESET RESOURCE message from MSC Major Cell Unavailable 77 219 32 347 Cause: NCP faulty or cell setup failed Cell Common Measurement Setup Failed 45 60 115 Cause: NodeB Unavailable NodeB Unavailable 11 42 61 Cause: NCP and CCP faulty RFN-BFN Drift Over Threshold 5 1 3 Cause: the difference float between the RNC clock reference RFN and the NodeB clock reference BFN is higher than the threshold. Cell Common Measurement Fault 85 12 18 Minor Cell HSDPA Reconfiguration Failed 10 Cause: The NodeB sends PHYSICAL SHARED CHANNEL RECONFIGURATION FAILURE to RNC. The NodeB does not send PHYSICAL SHARED CHANNEL RECONFIGURATION RESPONSE/FAILURE for a specified period of time. The cell fails to allocate code resource Common Channel Setup Failed 69 104 Common Channels of RNC and NodeB Mismatching 62 Cause: the AUDIT RESPONSE message reported by the NodeB includes the transport channel information that is not recorded on the RNC side. NodeB Audit No Rsp Cause: the RNC has not received audit response from NodeB. Cell HSUPA Unavailable Cause: either the local cell does not support HSUPA or E-DCH resoure operational state is disable. Cell HSDPA Unavailable Cauase: NodeB unavailable EMS User Login Failed Cause: the EMS user failed to login to system Cell Setup Failed 13 Cause: cell max DL power mismatch or common channel setup failed Cell Max DL power mismatch Cause: the Max DL power is mismatch between the cell and the local cell. Cell HSDPA Setup Failed
