E9-1-1 Call Taker (PSAPs) voice and data network services Creates options for deployment configurations and service delivery Extend integration and collaboration to broader community Mediates or facilitates access to services Opt-in subscription models PSAPs pulls info and controls information that can be pushed Creates context for an emergency service request Emergency context over request and service response A foundation for additional value-add services Integrated voice and data via IP and VoIP technologies Extensible to deliver various application services ATIS ESIF TF34 - Emergency Services Network (ESNet)
Emergency Services Network Standards Allows ESNet to mediate and present services for the PSAP. Services can be accessed directly as deemed appropriate.
Service C (EPES) Service A (EPES) Service B (EPES) ESMI and EISI Service Interaction Example ESNet PSAP Service Mgmt EISI ESMI CESE Response Gateway EISI ALI becomes a special case of a “Service”. Communication to the PSAP is generalized.
