Which typical component is NOT included in a communication center?

The selection of "Media line" as the component not typically included in a communication center is accurate. In a public safety communication center, the primary components focus on efficient emergency response and communication with the public and law enforcement.

911 incoming telephone lines are essential for receiving emergency calls directly from the public. Teletype systems, while less common today, were historically used for messaging and are still relevant in some contexts for inter-agency communication. Computer-Aided Dispatch (CAD) systems are critical for managing the logistics of emergency response, allowing telecommunicators to track incidents, deploy resources, and provide real-time information to responders.

In contrast, a media line, which refers to a line designated for communication with the press or media outlets, is not a standard function of a communication center. These centers are primarily focused on public safety operations rather than managing external communications with media, which is typically handled by specialized public information officers or departments. Therefore, recognizing that a media line does not fit the essential functions of a communication center clarifies why it is the correct choice in this context.
