A circuit group unblock response (CIRGRPUNBLKRSP) indication is delivered to the application when the ISUP layer receives a circuit group unblocking acknowledgment message (CGUA) from the far exchange. The application must consider the referenced circuits to be locally unblocked.
The rangStat member of the status event (SiStaEvnt) structure is populated when CIRGRPUNBLKRSP indications are delivered to the application.
