Abstract The base station control maintenance module standby system includes two base station control maintanance modules (CMM0 and CMMH1), the described two modules are connected to Abis interface and data clock interface, and it is characterized by that it also includes standby control device connected between first module and second module. It possesses duplex machine warm standby function, and utilizes main interface unit and standby interface unit to make main CMM and standby CMM retain layout data cynchronization and clock and frame number cynchronization between them, and when the main board is faulted, it can automatically switched to standby board, and the switching between main module and standby module does not result in chain breakage of traffic and signalling chain link so as to greatly raise the reliability of base station system.
