i1 = document older strategies for VoIP into
9-1-1
i2 = standard way to support VoIP on current
E9-1-1 using mechanisms developed for
wireless

All new network, databases, interfaces,
procedures, etc
Having said that, the basic process of how we
answer calls doesn’t change
All of public safety on an IP network =
Emergency Services IP Network (ESInet)

Is the Geographic Information System
Created as part of “Phase 2” wireless
upgrades
“Map” of service area
Contains political boundaries, streets,
addresses, service boundaries
Routing for lat/lon is point in polygon
Routing for civic is (theoretically) geocode +
PinP
Layer replication from GIS to ECRF
NENA 08-751 – Requirements
NENA 08-002 – Architecture (Stage 2)
NENA 08-003 (in review) – Detailed interface
& functions
Legacy Selective Router Gateway
Uses Tandem to Tandem transfers to allow
◦ ESInet originated call to terminate/transfer to
Selective Router terminated PSAP
◦ Selective Router originated call to
terminate/transfer to ESInet terminated PSAP
Uses ALI with E2 to interwork location
Comprehensive “what has to be done” to
move the entire system
Creation/upgrade/maintenance of databases
