METHOD FOR RESTARTING ATM PVC CONNECTION IN OPEN ATM SWITCHING SYSTEM

摘要

PURPOSE: A method for restarting ATM(Asynchronous Transfer Mode) PVC connection in an open ATM switching system is provided to promptly restore connection information even if a switching system or work station is gone down. CONSTITUTION: If an AIM(ATM Interface Module) is gone down, a GSCCF(GSMP Slave Connection Control Function)(242) of an SMC(Switch Management Controller)(24) resets ATM PVC(Permanent Virtual Connection) with having connection information existing in a memory database. If the SMC(24) is gone down, the GSCCF(242) of the SMC(24) resets ATM PVC point-to-point and point-to-multipoint connection to the AIM with connection reset information and restores ATM PVC point-to-point and point-to-multipoint connection information in a database existing in the SMC(24). If a work station is gone down, a TMN(Telecommunication Management Network) agent(15) reconstructs an MIB(Management Information Base) with root and leaf connection information which are point-to-point and point-to-multipoint connection information searched for from a database of an ACC(ATM Call Controller).
