This blog post is the second in a two-part series with two MCP experts, John Cunnington and Nancy Pollock, who together have more than of 80 years of experience in public safety communications. This blog post is part of our Let's Evolve 911 campaign that commemorates the 50th anniversary of the first 911 call, which took place 50 years ago this year.
In a previous post, Nancy Pollock and John Cunnington shared their perspectives on the evolution of 911 service in the United States over its first half century. In this post, they pick up where they left off, finishing with their insights regarding the sector’s future.
MCP Insights: In the previous post, you spoke of the addressing challenges that existed in the early stages of 911 service. But eventually, ANI/ALI and selective routers became ubiquitous—so the next big step forward was the introduction of CAD.
Nancy: To understand how important the introduction of CAD was, you have to understand how things were done before it arrived.
John: There was a manually created “run card” for every physical location—on that card was a list of the various emergency services that could be dispatched to that location. These run cards were the precursors of the datasets that are contained in today’s CAD systems. When a call came in, the dispatcher would pull the run card and use it to make the appropriate dispatching decisions. It was important that the run card was put back in its rightful place, so that it would be available for the next incident at that location. Keeping the cards updated was a major effort.
