最近几个月时间，经常有小区出现不固定时间的PCM无可用参考源告警，对应的告警代码为RXOTF-1B-1,时间不固定，出现此告警表现在话务统计上为小区可用率不足（小区倒站后会重启恢复正常），其他无异常，现在已经更换DXU单板和重新IDB数据，但依旧无效。现在不知道从何处入手，请指点。谢谢！

AO TF I1B:1 RBS 2202
Fault Name:DXU-opt EEPROM checksum fault
Remark:Onl in DXUs using 5 MHz optional sync referencey
Related fault:SO CF I2A:10 - DXU optional EEPROM checksum fault
Description:The EEPROM of the DXU optional synchronisation board contains corrupted data. This data is necessary for the CPU to control the 13 MHz VCO. The TU is unable to synchronise
Possible reasons:Probably a HW fault
Action:Try to power off/on the DXU. If this does not help, replace DXU.
正常情况下更换DXU可以解决的
