OVERVIEW
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 NG91-1 services.”

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
