This presentation provides a high level functional comparison between the legacy 9-1-1 and NG9-1-1 NENA i3 model including an overview of the major steps involved with migrating from legacy 9-1-1 to a NG9-1-1 NENA i3 model. A subjective review of the two different transition strategies published by NENA and ATIS (RFAI) will be discussed. The presentation will also discuss pro/cons between CPE and hosted applications that can be supported by an Emergency Services IP Network. These topics would be of interest to PSAP leadership, GIS support personnel as well as IT support personnel. 1 Myron S.

T IME AND M ONEY Illustration by Scott Chan When drafting a NG9-1-1 transition plan, ask the following: What operational capabilities are provided by the interim transition solution that are not already available in the legacy system? If not planned properly, the wrong transition strategy could be a very expensive diversion to NG9-1-1. 4 Synergem © 2011 All Rights Reserved.

RFAI P URPOSE – T RANSITION TO NENA I 3 Specifically, the RFAI architecture is intended to define a new interface between the new functional network elements, IPSR and RFAUA. These new functional elements serve to provide a transitional step from a legacy TDM environment to an IP environment that serves a PSAP. (ESIF-NGES-2009-028R17. DOC, P AGE 1)ESIF-NGES-2009-028R17.

RFAI T RANSITION As emergency service networks transition away from SRs, NENAs intent for NG9-1-1 is to smoothly transition to the NENA i3 defined architecture, ensuring a consistent environment among PSAPs and between ESInets. When the NENA i3 architecture is implemented, the RFAI is no longer needed. (ESIF-NGES-2009-028R17. DOC, PAGE 1)ESIF-NGES-2009-028R17.
