NG9-1-1 is expected to be an interconnected system of local/regional emergency services
networks. The boundaries of emergency service networks may vary, depending on local
requirements and organizational frameworks. However, at the core, each local NG9-1-1
network would include one or more PSAPs and the corresponding public safety
dispatching capabilities.7 Network interfaces will be needed for incoming calls, call
transfer to other PSAPs or dispatch centers outside the local network, and access to
databases and services outside the network
As is the case today, personal communication devices and commercial networks will
remain outside the emergency services internetwork. These devices and networks will
play an integral role as they interface with the NG9-1-1 network, but their deployment is
beyond the scope of this project. Call access using these technologies will be enabled by
corresponding standards, protocols, policies and operational procedures.

Introduction
The purpose of this document is to provide a preliminary Concept of Operations for the
Next Generation (NG9-1-1) system (or “system of systems”). The U.S. Department of
Transportation (DOT) understands that access to emergency services provided by 9-1-1
in today’s world of evolving technology will ultimately occur within a broader array of
interconnected networks comprehensively supporting emergency services, from public
access to those services, to the delivery and facilitation of the services themselves. More
specifically, DOT views NG9-1-1 as expanding and improving the capabilities of Public
Safety Answering Points (PSAPs) through new internetworking1 technologies.
