Public Safety Technology Leaders Announce Unprecedented Support for NENA Next Generation 9-1-1 Architecture Interface Standard known as i3

April 28, 2011

• Formal ratification of the NENA i3 standard is urged for optimum public safety communications performance and interoperability
• 911 Datamaster, Avaya, Cassidian Communications, Digital Data Technologies (DDTI®), GeoComm, RedSky Technologies, Solacom and TeleCommunication Systems demonstrate unprecedented collaboration in support of standards-based public safety technologies
• Public safety agencies encouraged to procure and implement NG9-1-1 solutions to fully align with the i3 standard in order to provide optimum mission critical communications performance and interoperability

Arlington, VA, April 28, 2011 — Today, eight leading vendors providing application and network functionality for public safety announced unprecedented collaboration in support of the immediate ratification of the National Emergency Number Association (NENA) i3 document (Functional and Interface Standards for Next Generation 9- 1-1, Standard 08-002 v1 and 08-003 v1) as the sole NG9-1-1 network architecture and interface standard. The NENA i3 standard represents an evolutionary standard(s) progression that masterfully builds upon previously- published and approved i1, i2 and i3 requirements and architecture documents.

The ability to dial 9-1-1 for emergency-related requests is a fundamental component of the public safety service delivery system in the United States, North America and abroad (via various dialing numbers (112, 611, etc). As such, the public expects 9-1-1 to work whenever and wherever it is needed. This level of 9-1-1 service availability has been achieved through the establishment of rigorous standards. Over time, these critical standards have evolved to adapt to the changes in technologies as well as requirements from the public safety community of users.

“We fully advocate that NENA remain the „Voice of 9-1-1‟ and continue its NG9-1-1 standards development and evolution efforts. Doing so will enable the public safety community [end-user agencies and business ecosystem members] to enhance and accelerate the development and deployment of NG9-1-1 emergency communication solutions,” said representatives from each company. “This will ensure that public expectation for a 9-1-1 system that has become the world‟s benchmark will remain robust and continue to protect life and property.”

NENA has been an active player in the 9-1-1 standards effort. Over the years, NENA has led the way in the development and evolution of essential technical, operational and administrative standards related to 9-1-1 service delivery. NENA‟s leadership and ability to pull together key members of the public safety community has truly enabled advances in overall service reliability and delivery for 9-1-1 communications.

The global shift to broadband, Internet Protocol (IP)-based communications and services, such as the internet, instant messaging, text messaging, video, and voice-over-IP (VoIP) requires a commensurate shift in 9-1-1 service standards. Once again, NENA has led the way in the standards development process through the evolution and approval of NG9-1-1 standards such as i1 and i2, which deal with VoIP technology integration.

As a result of their experience and expertise, NENA also recognized that a single NG9-1-1 network architecture and interface standard would be imperative to foster competition, control costs and accelerate NG9-1-1 adoption.

“In conclusion, a single comprehensive and open (non-proprietary) standard such as i3 is absolutely essential to achieve reliable, fully interoperable NG9-1-1 communications; and to realize the full potential and benefits associated with receiving non-traditional data types to 9-1-1,” company representatives further stated.
