NEXT GENERATION 9-1-1OVERVIEW

ESINET AND I3 FUNCTIONAL ELEMENTS

ESINET

“An ESInet is a managed IP network that is used for emergency services communications, and which can be shared by all public safety agencies. It provides the IP transport infrastructure upon which independent application platforms and core functional processes can be deployed, including, but not restricted to, those necessary for providing NG9-1-1 services.”

I3 FUNCTIONAL ELEMENT

Functional elements are the applications, databases and hardware that are attached to the ESInet. These components perform the following functions:

1. Routing2. Call Setup3. Service Provider Connectivity4. Security5. Information Services

MOVING FORWARD

ACHIEVABLE GOALS (2013-2014)

• Deployment of the ESInet• Identification of secure/hardened facilities

• i3 Functional Elements and/or Collocation Space• Deployment of i3 Functional Elements to support

improved wireless call routing capability• ECRF with PSAP Polygons

• Service provider connectivity• LNG, BCF, etc.

• PSAP connectivity / policy development• LPGs & ESRP/PRF

ACHIEVABLE GOALS (2015-2016)

• Full functional element deployment• ECRF/LVF – Address data not completely ready for use

until 2015• LIS & CIDB – Will require new service provider processes,

vendor processes and training
