Public Safety Answering Point (PSAP)
The final destination of an E911 call (where the 911 operator sits) is a Public Safety Answering Point (PSAP). There may be multiple PSAPs within the same exchange or one PSAP may cover multiple exchanges. The territories (Emergency Service Zone) covered by a single PSAP is based on the dispatch and response arrangements for the fire, police, and medical services for a particular area. Most PSAPs have a regional Emergency Service Number (ESN), a number identifying the PSAP.
The Caller Location Information (CLI) provided is normally integrated into emergency dispatch center's computer-assisted dispatch (CAD) system. Early CAD systems provided text display of the caller's address, call history and available emergency response resources. In 1994, working in cooperation with the emergency response agencies of Covington, KY, 911 Mapping Systems, Inc. founded in 1992 by Robert Graham Thomas Jr., implemented the first real-time on-screen E911 street map display to highlight the caller's position, nearest available emergency responders and other relevant information such as fire hydrants, hazardous materials and/or other data maintained by the city. Shortly thereafter, integrated mapping became a standard and integral part of all CAD systems and continues to evolve alongside 911 response technology. For Wireline E911, the location is an address. For Wireless E911, the location is a coordinate. Not all PSAPs have the Wireless and Wireline systems integrated.

Famous quotes containing the words public, safety, answering and/or point:
“Mass ought to be in Latin, unless you cd. do it in Greek or Chinese. In fact, any abracadabra that no bloody member of the public or half-educated ape of a clargimint cd. think he understood.”
—Ezra Pound (1885–1972)
“Perhaps having built a barricade when you’re sixteen provides you with a sort of safety rail. If you’ve once taken part in building one, even inadvertently, doesn’t its usually latent image reappear like a warning signal whenever you’re tempted to join the police, or support any manifestation of Law and Order?”
—Jean Genet (1910–1986)
“Politeness is as much concerned in answering letters within a reasonable time, as it is in returning a bow, immediately.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“The end of all stories, even if the writer forebears to mention it, is death, which is where time stops short. Sheherezade knew this, which is why she kept on spinning another story out of the bowels of the last one, never coming to a point where she could say: “This is the end.” Because it would have been.”
—Angela Carter (1940–1992)
