小区级告警查看：ZEOL，ZEOH（历史告警） BSC级告警查看：ZAHO，ZAHP（历史告警）。 故障载频、小区查看：ZEEL:BL:; 小区闭锁：闭锁: ZEQS:BTS=[BTS ID]:L; 解锁： ZEQS:BTS=[BTS ID]:U; 载频闭锁：闭锁： ZERS:BTS=[BTS ID],TRX=[TRX ID]:L:; 解锁： ZERS:BTS=[BTS ID],TRX=[TRX ID]:U:; 重启BCF： ZEFR:[BCF ID]:; ZEAO Nokia常见故障分析分析 TR掉话 小区的TCH TR Fail类型的掉话可能由载频故障引起，或是基站分枝表和Abis口上的时隙不一致引起。可以查看2993告警是否存在。指令：ZAHO 2993 BTS AND TC UNSYNCHRONIZATION CLEAR CALLS ON ABIS INTERFACE Meaning Calls have been cleared three successive times on the same Abis interface channel due to BTS and transcoder unsynchronisation. Supplementary information fields 1 identifier of the base station 2 identifier of the TRX 3 identifier of the radio time slot 4 number of external PCM circuit 5 time slot of external PCM circuit 6 sub-time-slot of external PCM circuit 若是一个BSC下较多的小区都存在TCH TR Fail的掉话，则可能是ET_PCM电路上的某个时隙出现问题。可以查看是否存在2992告警。指令：ZAHO。 2992 BTS AND TC UNSYNCHRONIZATION CLEAR CALLS ON A INTERFACE Meaning Calls have been cleared repeatedly on the same A interface circuit due to BTS and transcoder unsynchronisation and the number of successive releases has exceeded the limit defined in the PAFILE alarm parameter (alarm limit for successive remote tc failures). Supplementary information fields 1 number of PCM circuit Indicates: - number of external PCM circuit if GSW and unsubmultiplexed A interface are in use - number of SMUX PCM circuit if GSW and submultiplexed A interface are in use - PCMCON record index if GSWB is in use 2 time slot of the above-mentioned PCM circuit 3 circuit identification code 4 PCM circuit part of the circuit identification code In T1 (ANSI 1.544 Mbit/s) environment the value is 0xFFFF. 5 time slot part of the circuit identification code In T1 (ANSI 1.544 Mbit/s) environment the value is 0xFF. 6 number of external PCM circuit 7 time slot of external PCM circuit 8 sub-time-slot of external PCM circuit 9 number of trans
