| 单词 | E911 (Enhanced 911) |
| 释义 | E911 (Enhanced 911) An enhanced version of the 911 system used in the United States for calls for emergency assistance from police, fire, and ambulance services. Calls to 911 are routed to a public safety access point (PSAP). E911 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.Wireline and cellular service providers both are required by the Federal Communications Commission (FCC) to support E911. VoIP over the Internet presents considerable E911 difficulties as the location of the caller can be difficult, if not impossible, to determine. See also 911, FCC, Internet, PSAP, and VoIP. |
