Emergency communication systems, Orange County, Florida, Telephone systems
Several alternate systems for use in implementing the 911 emergency system in Orange County, Florida were investigated. The proposed systems were compared with the already existing systems on the basis of reliability, response time, and cost. System reliability was the prime consideration of the study. Flow charts of each system were formulated in order to determine the functions required of equipment and humans. The reliability was then determined by examining the difficulty of the tasks that each was required to perform. Reliability models of the present and proposed systems were constructed. By examining these models and comparing the reliabilities, response times, and costs, the most advantageous system configurations were determined. Two systems, Emergency Operator Call Transfer and Emergency Operator Call Relay, were selected as the most desirable; there were no appreciable differences in their reliability, response time, and cost.
