12. ATIS ESIF TF34 - Emergency Services Network (ESNet) 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

13. Emergency Services Network Standards Allows ESNet to mediate and present services for the PSAP. Services can be accessed directly as deemed appropriate.
