Coordination request message

The coordination request message is used by the application to request a coordinate state change to a subsystem (SCCPCoordRqst) or to accept a coordinated state change (SCCPCoordResp) request from a backup signaling point. This message is also received by the application to indicate an incoming coordinated state change request from a backup signaling point (SCCPCOORDIND) or to indicate an incoming coordination confirmation from a backup signaling point (SCCPCOORDCFM).

This message is also used as an indication to the application of an unsolicited subsystem state change or signaling point state change.
