9-1-1 Database Maintenance
Nortex works with the local counties on updating and managing the 9-1-1 GIS (Geographic Information System) database. The GIS database provides 9-1-1 telecommunicators location information related to the calling telephone number. The telephone company or mobile service provider may provide in addition to the calling party phone number an address associated with that 10-digit phone number. A name also may be displayed in the ALI (Address Location Information) window, much like caller ID features.
The information is displayed on a computer screen in front of the telecommunicator along with pertinent information about emergency responders for that location.
Nortex maintains maps at the Public Safety Answering Point detailing a more exact location of the caller which could then be passed on to the emergency responders; law enforcement, fire or medical.
