NENA development step: i 1

NENA standard name: (Immediate, early methods) not a standard

Description: Supports fixed VoIP callers and delivers calls to either a 10-digit emergency line or thru a CLEC interconnection (traditional E911). Location information is not provided. No PSAP equipment changes.

NENA development step: i 2

NENA standard name: 08-001 Interim VoIP Architecture for Enhanced 911 Services (dated December 2005)

Description: Supports ANI, ALI and selective routing. Delivers calls from both fixed and nomadic VoIP users. No PSAP equipment changes — requires wireless-type ALI interface (such as E2), and a new IP-based call originating network interfacing to current E911 systems. Note: Current forms of VoIP to E911 are not full Interim Solution, although they are often referred to a i2. They are actually pre-i2 as they do not provide all major aspects of the Interim Solution design.

NENA development step: i 3

NENA standard name: 08-00x Functional and Interface Standards for Next Generation 9-1-1 (expected approval 4Q2006), includes architectural design

Description: Basis for Next-Generation 911 (NG911). Supports ANI, ALI, Selective Routing functionality, real-time text messaging and multimedia (still images and full streaming video). Delivers calls from fixed, nomadic and mobile VoIP caller and from ILEC, CLEC and cellular wireless networks via IP transport. Supports extended IP and data capabilities at the PSAP, access to a wide variety of distributed databases and elimination of the physical selective router switch. Will be fully integrated into the National Emergency Calling IP Network.
