The SCP uses the N-EVENT-REPORT to inform the SCU of the verification status. See Section BBB.3 “Use Cases” in PS3.17 .

If the Event Type ID = 1 then the verification is still in progress, and the SCU must wait until another event is received. See Section BBB.3.2.2 “Transactions and Message Flow” in PS3.17 .

If the Event Type ID = 2 then the verification process has been completed. The SCU may use the returned value of the Treatment Verification Status (3008,002C) to determine whether or not the beam is ready to be delivered, or if a machine adjustment or override needs to be made. See Section BBB.3.2.2 “Transactions and Message Flow” in PS3.17 .
