26.11 Emergency E911 Phone Number Services

This section describes the device's support for emergency phone number services. The
device supports the North American emergency telephone number system known as
Enhanced 911 (E911), according to the TR-TSY-000350 and Bellcore's GR-350-Jun2003
standards. The E911 emergency system automatically associates a physical address with
the calling party's telephone number, and routes the call to the most appropriate (closest)
Public Safety Answering Point (PSAP), allowing the PSAP to quickly dispatch emergency
response (e.g., police) to the caller's location.
Typically, the dialed emergency number is routed to the appropriate PSAP by the
telephone company's switch, known as a 911 Selective Router (or E911 tandem switch). If
the PSAP receives calls from the telephone company on old-style digital trunks, they are
specially formatted Multi-Frequency (MF) trunks that pass only the calling party's number
(known as Automatic Number Identification - ANI). Once the PSAP receives the call, it
searches for the physical address that is associated with the calling party's telephone
number (in the Automatic Location Identification database - ALI).
