Circuit group block response

A circuit group block response (CIRGRPBLKRSP) indication is delivered to the application when the ISUP layer receives a circuit group blocking acknowledgment message (CGBA) from the far exchange. The application must consider the referenced circuits to be locally blocked.

The rangStat member of the status event (SiStaEvnt) structure is populated when CIRGRPBLKRSP indications are delivered to the application.
