Due to the critical nature of E911 service, the control and timely repair of troubles is demanded. As the primary E911 customer contact, the SSC/MAC is in the unique position to monitor the status of the trouble and insure its resolution.
System Overview
~~~~~~~~~~~~~~~
The number 911 is intended as a nationwide universal telephone number which provides the public with direct access to a Public Safety Answering Point (PSAP). A PSAP is also referred to as an Emergency Service Bureau (ESB). A PSAP is an agency or facility which is authorized by a municipality to receive and respond to police, fire and/or ambulance services. One or more attendants are located at the PSAP facilities to receive and handle calls of an emergency nature in accordance with the local municipal requirements.
An important advantage of E911 emergency service is improved (reduced) response times for emergency services. Also close coordination among agencies providing various emergency services is a valuable capability provided by E911 service.
1A ESS is used as the tandem office for the E911 network to route all 911 calls to the correct (primary) PSAP designated to serve the calling station. The E911 feature was developed primarily to provide routing to the correct PSAP for all 911 calls. Selective routing allows a 911 call originated from a particular station located in a particular district, zone, or town, to be routed to the primary PSAP designated to serve that customer station regardless of wire center boundaries. Thus, selective routing eliminates the problem of wire center boundaries not coinciding with district or other political boundaries.
The services available with the E911 feature include:
Forced Disconnect Default Routing
Alternative Routing Night Service
Selective Routing Automatic Number
Identification (ANI)
Selective Transfer Automatic Location
Identification (ALI)
