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 - Co-Chairs, Terry Reese & Guy Caron ENP
    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 will review and add to the current NENA standard for the i3 architecture that provides call and data handling functionality between 9-1-1 call originators and 9-1-1 call centers (PSAPs). Planned future work is listed in Section 2.6 of version 2. Major topics planned for updating in version 3 of the standard include: (1) Network routing, performance and security; (2) Core, ancillary, and transitional functions; (3) Data definition, including location, GIS, and additional data, including XML; (4) Next generation 9-1-1 PSAP multimedia and other data interfaces; and (5) PSAP management-testing interface. ANSI project initiation notice was published in May 2015 for version 3. Estimated to begin review process 1Q2018. Calls are Thursday's at 10:30 am to Noon ET. 20161003_ISF i3 v3 (ANS)_CharterApproved 20161025

      • Conveyance of Emergency Incident Data Document (EIDD), Co-Chairs Henry Unger,  Tony Dunsworth & Rick Blackwell ENP    The Conveyance of EIDD Working Group will focus on developing an ANSI accredited NENA/APCO Standard for transporting (conveying) Emergency Incident Data Documents (EIDDs) between systems (FEs). The data elements contained in EIDDs are defined in a soon to be released joint APCO/NENA ANS. The new Standard to be developed by this NENA/APCO working group will define how EIDDs are exchanged and transported from NG9-1-1 networks and systems. Expertise in information sharing and specifically in using web services and other protocols is desired. Operational expertise familiar with the needs for exchanging data between call takers and dispatchers, emergency responders and other user systems is also highly sought. We are looking for a well-balanced group that will include contributions from technical and operational subject matter experts. ANSI project initiation notice was published in May 2015. Calls are Friday's at  2-3 pm ET.  20160201_ISF-EIDD conveyance_20160823 CharterAppvd


  • Emerging Topics - Co-Chairs, Paul McLaren & Randall Gellens 
    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. Calls are the 2nd Thursday of every month at 4 pm ET for 1 hour.
  • Internet of Things (IoT) & & External Applications WG, Co-Chairs Randall Gellens & Dwight Purtle, ENP     A new Working Group on IoT (Internet of Things) and Apps (external applications) is seeking volunteers to assist in creating a document describing the impact of IoT devices and emergency applications on NG9-1-1, in cooperation and with input from NPSTC and other Public Safety organizations. This document will provide guidance to 9-1-1 professionals, application/device vendors, and data management/monitoring entities for NENA-endorsed methodology for NG9-1-1 interaction by IoT devices and emergency calling applications. The group may also determine mechanisms by which attachments (such as static image and video media) are either conveyed with or made available within a 9-1-1 call and determine how data provided by applications or devices is made available to and accessed by call takers and responders. Additionally, the WG may determine mechanisms (signaling etc.) by which applications and devices place automatic or manual 9-1-1 calls, including situations where the person initiating the call is remote, or gets bridged into a 9-1-1 call.                   Calls are Tuesdays 1:30-2:30 ET.
