Emergency 911 calls

The Enhanced 911 (E911) systems installed in many jurisdictions in the U.S. are equipped so that by
dialing a service code (911 in the U.S.), a victim of a fire, accident, crime, or medical emergency may
quickly access a public safety agency that will dispatch the appropriate response. The public E911 system
maintains a database that stores location and background information to aid public safety agencies in
responding quickly with the appropriate assistance. Information about the calling party can be triggered
by the transmission of a Caller's Emergency Service Identification (CESID) number over Centralized
Automatic Message Accounting (CAMA) trunks when the call originates from behind a PBX. 911 calls
from a station on a PBX not equipped with CAMA trunks (or an adjunct computer system associated with
CAMA trunks) will not provide the E911 system with the information required to identify the location of
the person placing the call. Instead, the E911 system will only be able to identify the location of the trunk
termination at the PBX.
Enhancement to E911 includes the ability to report the Emergency Location Extension as the CPN. You
can manually correlate the CPN with the phone location after the phone is moved, instead of having to
update the Automatic Location Information database for the PSTN after every telephone move.
Detailed description
The Enhancement to E911 feature allows transmission of identifying information (in the form of the
CESID over CAMA trunks or the CPN over ISDN trunks) as to the extension number of a DID station
associated with the calling party. The calling party may be at or near a station on a remote port network,
or may be at a remote location served by an off-premises station.
