ABSTRACT:
A method of identifying a segment and end-to-end OAM flow VPC context table for one of a plurality of VCCs corresponding to the VPC. Each VCC has a context table. Each VCC context table has a pointer. The pointer contains the address of the context table for the segment and end-to-end OAM flow VPC. Provisioned connections supported by the ATM switching system are repeatedly scanned. If a VCC has an active F4-to-F5 OAM process, the pointer is extracted from that VCC's context table, identifying the context table of the corresponding segment and end-to-end OAM flow VPC. If the VPC is in the VP-AIS alarm state, the current VCC outputs a VCC-AIS cell. A continuity check is repeatedly performed by updating the appropriate F4 OAM connection context table whenever a VCC cell is received on a corresponding F5 connection, preventing the F4 connection from raising a continuity check alarm.
