9-1-1 Goes to Washington

Interconnection & Security Committee

Submit an Issue to the

NENA Development Group



This committee is focused on the technical development, maintenance and evolution of NG9-1-1 systems architecture, both for real-time interfaces within the ESInet as well as those external interfaces into the system.

These would include aspects such as system management, architecture and interfaces definitions. The committee also oversees the technical integration and operational impacts of existing and newly formed security (encryption, authentication etc.) technologies on the overall ‘system’.

  • NG9-1-1 Architecture Evolution - Chair, Terry Reese
    The mission of the NG9-1-1 Architecture Evolution Subcommittee defines issues that involve the ESInet architecture, as well as the i3 functional elements that ride on it and their associated interfaces. It is also expected to handle both the evolution of the i3 ESInet and interconnection with evolving originating and PSAP networks.

    • Workgroups

      This Work Group will:  (1) Analyze current Wireless Home Phone (WHP) deployments with regard to wireline and Interconnected VoIP E9-1-1 parity for devices that are not generally mobile and provide as appropriate new recommended NENA standards to allow the most precise location information.  (2) Analyze current Femtocells and Small Cell deployments in regard to wireline and Interconnected VoIP E9-1-1 parity for devices that are not generally mobile and provide as appropriate new recommended NENA standards to allow the most precise location information.  (3) Analyze the greater growing use of CMRS wireless handsets with Wi-Fi voice capability or Wi-Fi only handsets for indoor Wi-Fi calling situations that are not generally mobile and the current default to wireless E9-1-1 Phase 1 and Phase 2 calling.  (4) Analyze other similar current and near-term potentially problematic cases and expected new situations, and either include in a standard to formally establish expected methods or define for additional future work.

    • Emergency Services IP Network Design, ChairJim Lockard & Joel McCamley:                                                                                                                                        This group will review the existing NENA 08-506 in order to improve several areas:  Assignment of Autonomous System Numbers (AS) Numbers - including interaction with American Registry for Internet Numbers (ARIN);  Uniform DNS entries for ESInet's   and  Coordinate & document .empirical testing on the performance thresholds described in the document. 

      The EIDD is the mechanism to move data between Public Safety Agencies, Systems and Applications. This WG will develop a standard specification for the sending and receiving EIDDs, enabling data exchange interoperability between and among i3-compliant PSAPs and their associated response agencies.


  • Emerging Topics - Chair,Paul McLaren 
    The Emerging Topics Sub-Committee is responsible for developing standards, requirements documents or information documents for all issues related to future products and services that may affect 9-1-1.  The committee’s goal is to monitor industry, science, and technology activities for any such items with implication for 9-1-1, research possible impact and draft appropriate documents that can be forwarded to other NENA Committee's or regulatory and industry standard organizations in order to ensure all devices may access 9-1-1 anytime and anywhere.  The Sub-Committee pools the respective knowledge of its members to understand new technology implications, bring appropriate technologies to the attention of the 9-1-1 community and describe the impact on emergency call services.
