E911 and Cisco Emergency Responder Terminology (continued)
Emergency service zone. The area covered by a given PSAP. This area usually
includes several police and fire departments. For example, a city and its suburbs
might be serviced by one PSAP.
Each ESZ is assigned a unique emergency service number (ESN) to identify it.
Master street address guide. A database listing of all valid street address ranges
within a community, the contents of which is typically managed by a local
government organization. The MSAG database service can be managed by a local
government organization, an incumbent local exchange carrier, or by a database
service provider (often the same as the ALI database service provider).
National Emergency Number Association. The organization that recommends
data and file formats for ALI definitions and other emergency call requirements
in the United States. Cisco Emergency Responder uses the NENA formats for
ALI data export files. Your service provider might have additional restrictions on
data format, so ensure that your ALI entries abide by your service provider's
Public safety answering point. This is the organization that receives emergency
calls, for example, the 911 operator. The PSAP is staffed by people trained in
handling emergency calls. The PSAP talks to the emergency caller and notifies
the appropriate public service organizations (such as police, fire, or ambulance)
of the emergency and its location.
