Technology and standards identified and considered within
this document are expected to support a number of system
engineering qualities, including scalability, extensibility,
reliability, configurability, and most important, interoperability.
The system must support scalability so that it can be sized to fit the
needs of PSAPs and 9‑1‑1 authorities of differing sizes. PSAPs
that protect the nation’s largest cities (or states or regions) as
well as those that protect individual communities will be able to
implement an NG9‑1‑1 system or connect to an NG9‑1‑1 network
to access the features and services of NG9‑1‑1. The scalability of
the system should also permit horizontal and vertical scaling to
allow individual NG9‑1‑1 systems to expand or change to manage
such factors as additional call volume and increased network
traffic, the addition of PSAPs, consolidation of PSAPs, addition
of roadways, and changes in jurisdictional boundaries. System
scalability should also make the system more affordable to 9‑1‑1
authorities because they can implement a system that is appropriately
sized for their operations rather than having to adhere to a “one
size fits all” rationale.

Scalability limits are expected to depend
on conditions such as political boundaries at state or sub-state
levels, realistic bandwidth limitations in the networks, and database
size and security management issues. System components and
subsystems would be selected that support scalability needs.
The system must be extensible in that it must permit future
technologies to be woven into the system without requiring
wholesale replacement. Although future advances in technology
cannot be predicted with certainty, the design principles of the
system support quick adaptation of emerging technologies.

Introduction

The purpose of this document is to provide an Architecture Analysis
for the Next Generation 9‑1‑1 (NG9‑1‑1) System (or “system
of systems”). The U.S. Department of Transportation (USDOT)
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 facilitation of the services, to the delivery of the
emergency information to dispatchers and first responders.
