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.

“We might make a public moan in the newspapers about the decay of conscience, but in private conversation, no matter what crimes a man may have committed or how cynically he may have debased his talent or his friends, variations on the answer “Yes, but I did it for the money” satisfy all but the most tiresome objections.”
—Lewis H. Lapham (b. 1935)
“There is no calamity which a great nation can invite which equals that which follows a supine submission to wrong and injustice and the consequent loss of national self-respect and honor, beneath which are shielded and defended a people’s safety and greatness.”
—Grover Cleveland (1837–1908)
“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)
“A poet’s work is to name the unnameable, to point at frauds, to take sides, start arguments, shape the world, and stop it going to sleep.”
