Bandwidth Glossary

sometimes it's not elementary


An enhanced version of the 9-1-1 system used in the United States for calls for emergency assistance from police, fire, and ambulance services. Calls to 9-1-1 are routed to a public safety answering point (PSAP). E9-1-1 identifies the location of the caller, routes the call to the appropriate local PSAP, and provides the PSAP with location information in order to speed response. Landline and cell service providers both are required by the Federal Communications Commission (FCC) to support E9-1-1.
