9-1-1 equipment allows communication centers to receive emergency calls utilizing the 9-1-1 network. This includes Automatic Location Identifier (ALI), Automatic Number Identifier (ANI), ______________.

The correct answer highlights the essential components that work in conjunction with the 9-1-1 network to enhance emergency response capabilities. In particular, mapping systems provide dispatchers with crucial geographic information, allowing them to identify the location of incidents more accurately and efficiently. This is vital for directing emergency responders to the scene as quickly as possible.

Recording equipment is similarly important in a communication center as it ensures that all calls are documented. This is necessary not only for quality assurance and training purposes but also for legal records in the event of inquiries or disputes related to the calls.

Computer Aided Dispatch (CAD) systems integrate the mapping and call information to streamline the dispatch process. They allow for real-time management of resources, tracking the status and locations of emergency services.

Other options, while they may mention relevant technologies, do not encompass the full set of systems that work integrally with the 9-1-1 network in the way that mapping systems, recording equipment, and Computer Aided Dispatch do. This combination is essential for an efficient and effective response to emergencies.
