The proposed standard mandates an immediate electronic acknowledgement by the CAD System back to the alarm monitoring company’s software application server.  

• If the CAD System rejects the call for some reason, the CAD will send a Rejection Response Transaction (RRT) back to the alarm company that clearly states the reason for the rejection.  The alarm monitoring company operator will then take appropriate action according to the company’s policies and practices. 
• If the CAD System accepts the new event, the CAD will send an Accept Response Transaction (ART) back to the alarm company that contains the PSAP’s event number(s) associated with the newly created call-for-service.
