Emergency Alert System
Manufacturers and Service Providers Develop Profile for Using
Common Alerting Protocol in Broadcast EAS
Collaborate on Utilizing Open Standard to Facilitate
Interoperability of Advanced Emergency Alert System
Capabilities in the U.S.
25 September 2008 — The EAS-CAP Industry
Group – a broad coalition of equipment, software and service
providers to the Emergency Alert System - today announced that
its members have released a draft profile for the effective use
and translation of the open, non-proprietary Common Alerting
Protocol (CAP)1 for the next
generation of broadcast EAS.
The profile will be
an important step towards improving interoperability across
agencies, jurisdictions, systems and vendors, helping to ensure
that the public benefits from improved capabilities to
communicate weather, civil, AMBER and other alerts via broadcast
The Industry Group will provide this
profile as a recommendation to U.S. governmental agencies and
industry associations on the use of CAP for EAS purposes,
including the FCC, FEMA, National Weather Service, and other
organizations. Group members intend to rapidly implement the EAS-CAP
within their own systems and equipment.
The EAS-CAP profile provides developers and
manufacturers guidelines as to which elements in a CAP message
are required for an EAS message, identifies how a mandatory
alert from a state/territorial Governor would be identified,
describes basic authentication and security features, recommends
accepted formats for audio messages, and other features.
The output of the Group’s work is publicly accessible on its
website www.eas-cap.org, and the Group will offer a mechanism
for public comment on that site. The Group plans to continue its
work to solicit feedback and provide recommendations to EAS
The Group was established in response to the July 2007 decision
by the Federal Communications Commission (FCC) to maintain EAS
and have all U.S. EAS participants adopt an ability to receive
messages using the Common Alerting Protocol (CAP) within 180
days after the Federal Emergency Management Agency (FEMA)
formally adopts CAP version 1.1 as a standard for EAS.2
FEMA’s announcement on CAP adoption is expected in the first
quarter of 2009.
The Common Alerting Protocol
(CAP) is a simple but general format for exchanging all-hazard
emergency alerts and public warnings over all kinds of networks.
CAP allows a consistent warning message to be disseminated
simultaneously over many different warning systems, such as
computers, wireless communications, alarms, and television radio
and cable via broadcast EAS.

About the EAS-CAP Industry Group:
The EAS-CAP Industry Group is an informal coalition of Emergency
Alert System equipment, software and
service providers. Using the best available information, the EAS-CAP
Industry Group has collaborated to
develop a voluntary profile for the interoperability of advanced
Emergency Alert System (EAS) capabilities in the United States
using the Common Alerting Protocol (CAP). Specifically, the
Industry Group collaborated to coordinate interoperable data
standards among Emergency Alert System equipment, software and
service providers. Further, the Industry Group will seek to
provide recommendations to U.S. governmental agencies and
industry associations on the use of CAP for EAS purposes.
The EAS-CAP Industry Group’s intention is to offer an
interoperable EAS-CAP data profile that is a freely
available resource for EAS participants, equipment, software and
service providers, to the benefit of public alert and warning
capabilities throughout the United States. It is the intention
of the Industry Group that any work product of the group be free
of copyright and intellectual property constraints.
