HISTORY OF 9-1-1
On January 12, 1968, in response to the urging of concerned citizens and officials for a standard, dedicated emergency telephone number, the American Telephone and Telegraph Company (AT&T) announced 9-1-1 would be made available throughout the country.
U.S. Government Code Section 531000 required the implementation of 9-1-1 emergency telephone systems throughout California. These systems established uniform emergency telephone communications for emergency police, fire, medical and ambulance services. Statewide implementation, including coin-free access from pay telephones was accomplished by December 16, 1985. California was the second State in the U.S. to have completed a 9-1-1 system.
Folsom’s 9-1-1 system was implemented in the early 1990’s. The system has been further upgraded with digital hardware offering many features enhancing the ability of the Public Safety Answering Point (PSAP) to determine caller location and phone number, and to deal with problematic calls.
Features of the Folsom Police Department’s 9-1-1 System include:
- Emergency Service Number - a code that designates each unique combination of public safety services within the City’s jurisdiction.
- Master Street Address Guide - a document prepared by the telephone company and the county 9-1-1 coordinator containing an alphabetical list of street names, address ranges, postal communities, and Emergency Service Numbers for each address where a telephone is located.
- Selective Routing - each telephone call is routed to the Public Safety Answering Point (PSAP) having law enforcement jurisdiction over the location of the calling instrument, as reflected by the Emergency Service Number.
- Automatic Location Identification - telephone database information on calling telephone number and location is displayed at each Public Safety Answering Point.(PSAP)
- Single Button Transfer - any 9-1-1 telephone call can be transferred by a Public Safety Answering Point (PSAP) to any other Public Safety Answering Point (PSAP) or to any telephone number as needed.
- Translation Services - the State of California provides a transfer number for translating services for 9-1-1 telephone calls in foreign languages. Folsom Police subscribes to AT&T Language Line Service, a commercial service providing telephone translation in over 124 languages.
- TTY/TDD - every Pubic Safety Answering Point (PSAP) must have a device capable to communicate with a hearing impaired caller.
