Operations and Call Processing

Core concepts

Call processing is the disciplined sequence: answer, gather, triage, dispatch, and document. Telecommunicators must master call prioritization, emergency medical dispatch (EMD) protocols, law/fire pre-arrival instructions, radio discipline, and CAD data entry. The questioning sequence (location, callback number, nature of emergency, injuries) is foundational; location and callback are gathered first because they survive a dropped call.

Operational traps

Questions test whether you know the difference between call-taking and dispatching, and the role of call triage when resources are scarce. Be precise about transfer vs. conference, abandoned/ silent calls, and abusive/ prank calls. Also recognize active assailant, hostage, and suicidal caller procedures as distinct protocols with specific do's and don'ts.

Quality and documentation

Every call should be time-stamped, and CAD narratives must be objective, factual, and free of opinion. Understand unit status (available, en route, on scene, transporting, out of service) and call disposition codes.

Worked example

A caller reports a house fire but cannot give an address. Rule of thumb: location first, then callback, then nature. Use ALI/ANI, ask for cross streets or landmarks, and confirm the callback number before gathering fire details. If the call drops, you still have the two elements that let you send help and re-establish contact.
