ABSTRACT:
An apparatus for and a method of duplex operation and management for an SMX-1 system, capable of minimizing a failure of the system and ensuring the consistency of data between the contents of database and the data being currently operated by two operation management subsystem modules (OMMs) operated in a fashion that when a failure occurs in one of the OMMs, the other OMM executes the function to be executed by the one OMM. The OMMs are connected to the target system by a highway interface unit and connected to a remote signalling network operations system (SIGNOS) by an X.25 network using a modem, one of the OMMs being in service to execute a management of network resources and a management of states of signalling networks, while the other OMM being standby.
