Response: THE RESPONSIBILITY FOR PRIMARY NOTIFICATION OF MUTUAL AID, HOSPITAL AND AMBULANCE SERVICES HAS BEEN REMOVED FROM THE COMMUNICATIONS CENTER AND PLACED WITH THE DEPARTMENT OF PUBLIC SAFETY EMERGENCY OPERATIONS CENTER. A TELEPHONE DATABASE HAS BEEN INSTALLED AND ACTIVATED ON AN IBM-AT PERSONAL COMPUTER FOR THE PRIME PURPOSE OF ALERTING DISASTER RESPONSE FORCES. THE SOFTWARE DELIVERS A SELECT MESSAGE TO PREDETERMINED TELEPHONE NUMBERS AND ELICITS ACKNOWLEDGING RESPONSES FROM OPERATORS ANSWERING THAT NUMBER. THE CALL LIST IS ENCODED IN PRIORITY LEVELS FOR CALLOUT MESSAGES. MESSAGES MAY BE ENTERED BY THE EMERGENCY OPERATIONS CENTER COORDINATOR FOR TRANSMISSION IN SUCH A MANNER AS TO ALLOW UPDATING OF INCIDENT INFORMATION AS IT PROGRESSES. ONCE ACTIVATED BY THE EMERGENCY OPERATIONS CENTER COORDINATOR, THE SYSTEM REQUIRES NO FURTHER ACTION FROM THE OPERATOR OTHER THAN MONITORING AND ACKNOWLEDGING INCOMING CALLS. THE SYSTEM, AS TESTED IN THE PRESENCE OF FAA REPRESENTATIVES, HAS CONTACTED AND RECEIVED ACKNOWLEDGEMENTS FROM THE PRI MARY RESPONSE AGENCIES WITHIN 6 MINUTES.
