Handling redundancy events

After binding to an ISUP user SAP, the application receives a status indication indicating the MTP redundancy or run state on the board. The event type associated with status indication (EVTSITSTAIND) indicates one of the following states:

State

Description

MTPSTANDALONE

Application is in a non-redundant configuration. Normal operation can begin.

MTPPRIMARY

The run state of MTP is primary on this board in a redundant board pair. Normal operation is allowed as long as the board remains primary.

MTPBACKUP

The run state of MTP is backup on this board in a redundant board pair, monitoring the status of the primary board. No active traffic passes through this SAP until the board becomes the primary member of the pair.
