EAS-CAP Industry Group Publishes Profile for the Common Alerting Protocol.

Contents

Members of the EAS-CAP Industry Group (ECIG) have announced the release of initial draft text for EAS-CAP Industry Group EAS-CAP Profile Recommendation EAS-CAP-0.1 with an invititation for public comment. The Common Alerting Protocol (CAP) specification was approved as an OASIS Standard in October 2005 and as an ITU-T Recommendation X.1303 in 2007-09.

CAP is a "simple but general format for exchanging all-hazard emergency alerts and public warnings over all kinds of networks. It allows a consistent warning message to be disseminated simultaneously over many different warning systems, thus increasing warning effectiveness while simplifying the warning task. CAP also facilitates the detection of emerging patterns in local warnings of various kinds, such as might indicate an undetected hazard or hostile act."

The CAP standard has now been implemented by dozens of companies, agencies and organizations. On July 30, 2008, the U.S. Department of Homeland Security's Federal Emergency Management Agency (FEMA) announced its intention to adopt an alerting protocol in line with CAP Version 1.1 as the standard for the Integrated Public Alert and Warnings System (IPAWS), during the first quarter of calendar year 2009. IPAWS is a network of alert systems through which FEMA is upgrading the existing Emergency Alert System (EAS).

The EAS-CAP Industry Group was formed as a broad coalition of equipment, software and service providers in response to a 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 FEMA formally adopts CAP version 1.1 as a standard for EAS.

Members of EAS-CAP Industry Group believe "the integration of this EAS-CAP profile into existing and planned systems will lay a foundation for migration to an upcoming FEMA CAP profile. Prior to the formation of the EAS-CAP Industry Group, numerous progressive companies were already involved in CAP messaging for EAS. However, each vendor used its own method for transporting the EAS parameters within a CAP message, raising the potential challenge of various EAS equipment and systems not being able to communicate with each other. The advent of this EAS-CAP profile will provide the basis for interoperability both among next generation EAS equipment and services, as well as between the EAS community and other communications channels."

ECIG is providing the 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 profile within their own systems and equipment. 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 media."

The draft Profile is based upon the CAP standard and FCC EAS Rules. "Public warnings intended for transmission over the Emergency Alert System (EAS) can be encoded in Common Alerting Protocol (CAP) messages in various ways. The EAS-CAP Profile represents a consensus among EAS equipment manufacturers and warning practitioners regarding a single recommended pattern for compatible encoding."

According to the published ECIG FAQ document, "The Industry Group is currently developing Test Vectors for all vendors to use in testing their devices on an individual basis, but no live device-to-device testing is planned at this time. We feel that each vendor using the individual tests within the Test Vector suite to be certain that their device reacts properly to each test will result in adequate compatibility testing... The purpose of the group is solely to develop technical standards to promote interoperability among EAS vendors in the context of the CAP 1.1 Standard. Issues of price, availability, and other marketing and sales questions are outside the scope of the group..."

Abstract: "Public warnings intended for transmission over the Emergency Alert System (EAS) can be encoded in Common Alerting Protocol (CAP) messages in various ways. A consensus among EAS equipment manufacturers and warning practitioners regarding a single recommended pattern for compatible encoding — the EAS-CAP Profile — is documented along with related recommendations.

Excerpts from the EAS-CAP Profile Recommendation

The following excerpts are adapted from the EAS-CAP Profile Recommendation EAS-CAP-0.1

From Section II, (EAS-CAP Industry Group Participants and Activities): "In May, 2008 an ad-hoc Industry Group of EAS equipment manufacturers and other interested parties convened for the purpose of facilitating the incorporation of the Common Alerting Protocol version 1.1 into the national Emergency Alert System (EAS) by devising a workable EAS-CAP Profile and associated technical and procedural recommendations. The Industry Group conducted an initial telephone conference call and thereafter utilized an online forum for the discussion of issues and the drafting of this document.

From Section IV, (Definitions): An EAS-CAP Profile Decoder is "a device or software application that performs one or more of the following tasks: (1) Using the EAS-CAP Profile, converts a CAP alert into the CFR 47 Part 11 Emergency Alert System (EAS) format, commonly referred to as the ZCZC string; (2) Using the EAS-CAP Profile, converts a CAP alert into a text string intended for display as video, or input into a Text to Speech converter, or as input for any other text display; and used in conjunction with an EAS alert.

From Section VI, (Discussion of items omitted or included in the Profile):

  • A. Included: for rendering of both text-to-speech and video display of EAS alerts from CAP messages, a method to announce and display [...] useful and specific information derived from the CAP message elements that can be used as part of the EAS alert broadcast [rather than generic information derived from the EAS Header Code]
  • B. Included: both a proprietary and non-proprietary audio format for use with attached audio files. While the non-proprietary WAV PCM audio files are free of any licensing fees, they will be significantly larger in file size than the proprietary, licensed-format MP3 files. This gives the individual CAP network architects the option to choose between low cost or low file size.
  • C. Not included: methods to originate and render CAP alerts using additional languages for EAS alert use; await forthcoming decisions by the FCC
  • D. Not included: recommended default values for the CAP Urgency, Severity, and Certainty element values corresponding to each EAS Event Code; leave this to system vendors and clients
  • E. Not included: definition of requirement for text-to-speech technology in an EAS-CAP Profile Decoder

From Section VII, (EAS-CAP Profile) Best practices which must be observed when encoding CAP messages intended for EAS broadcast... [see the Profile document for details]

From Section VIII, (CAP Message Processing for EAS)

A. One of the main purposes of this Profile is to ensure that CAP messages are rendered in EAS such that duplicate messages can be detected once the message is forwarded in the EAS domain. This means that for a given CAP message, all vendors must emit the exact same CFR 47 Part 11 "ZCZC" string. All characters, starting with the ZCZC header and ending with the hyphen before the LLLLLLLL field, must be identical.

B. Further, the Profile defines the content of the text string used as input to a Text-To-Speech element, or to a video character generator element. While there may be some local user and vendor customization, the intent here is that the generated audio and video is as similar as possible between EAS vendors. This intentional consistency among vendors allows CAP origination software to offer its users a reliable "preview" of what an EAS alert will look and sound like on air, regardless of which vendors equipment is used at the receiving end.

From Section IX, EAS Relay Network Security: While the EAS-CAP Industry Group does not propose to specify relay network or networks for EAS, it does make the following recommendations regarding EAS network security... Section 3.3.2.1 of the OASIS CAP 1.1 Specification includes the W3C recommendation for Digital Signatures and specifies an "enveloped" digital signature as the preferred mechanism for ensuring CAP message authenticity and integrity. The Industry Group recommends the implementation of this technique. This recommendation is not meant to preclude the use of additional methods for encryption and authentication within EAS Relay Networks...

From Appendix B CAP-V1.1 to EAS Validation Criteria: Incoming CAP-V1.1 messages SHALL be subjected to a validation step prior to acceptance for translation to an FCC Part 11 EAS alert. The purpose of this step is to determine whether or not to continue the translation based upon basic syntax and semantic requirements. It is recommended that the EAS-CAP Profile Decoder log any useful information about message validation. This step does not address message authentication. The source will be trusted based upon other authentication steps taken in a different layer of the communication.

Validation Philosophy: In this document we discuss the rules for validation of EAS-CAP Profile messages. There are also assumed rules for basic CAP validation. As of this writing, the "conformance rules" are not part of the CAP 1.1 Specification. There may be conformance rules that are being generated as part of future type acceptance of CAP 1.1 devices. This EAS-CAP Industry Group has wrestled with the issue of strict adherence to the CAP schema versus the potential rejection of a valid alert due to a trivial formatting error. We do not further address the issue of CAP conformance here, other than to say that if there are rules for CAP conformance that affect certification of EAS-CAP devices, then validation based on those rules will be performed first.

Error Signaling Philosophy: We realize that EAS-CAP is a part of the larger CAP community, and that messages that are in error for EAS renderers are not necessarily errors to the CAP community. Therefore, we have taken the following approach: if a message has an error that would be an error to any CAP receiver, we signal an error. If the message is in error only to an EAS-CAP Profile Decoder, we signal acceptance of the message, but do not act on it. Our intent is that the CAP community is not subjected to what they would consider to be erroneous Error messages.

Validation Overview: The CAP-to-EAS message validation procedure described below details the minimum requirements to enforce basic message verification. Specifically, the purpose of this validation step is to: (1) reject improperly formatted, improperly constructed, or damaged CAP messages. (2) ignore messages that do not contain sufficient information for the generation of a unique EAS message. (3) ignore CAP messages that are not intended for EAS translation. Once a CAP message passes the validation step, it may be subjected to an additional set of filters that will decide if a particular alert is to be placed on the air by a particular user...

CAP Required Elements: In the EAS-CAP Profile, we do not require that all CAP-required elements be present. We assume that a processing element in the chain before the EAS-CAP Profile Decoder has verified the format of the alert, and that the authentication scheme has delivered an intact message to the EAS-CAP Profile Decoder.

EAS-CAP Required Elements: "In order to translate a CAP message into an EAS message, another set of optional CAP elements are required. These elements have been defined in the EAS-CAP Profile in order to guarantee consistent translation into an EAS message. These elements of the CAP message are not necessarily required as elements in CAP, but are required by EAS. Some elements are required for proper translation into an EAS message, and thus are included in a specific minimum set of EAS-CAP required elements. Other elements may be considered of lesser importance. Some of these elements will have defined default values..."

From the ECIG Announcement

September 25, 2008.

The EAS-CAP Industry Group (ECIG) — 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)* 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 media.

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 profile 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 stakeholders.

Background

The EAS-CAP Industry Group was established in response to the July 2007 decision by the U.S. 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.** 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 FCC Emergency Alert System (EAS)

The Emergency Alert System (EAS) is a U.S. national public warning system that requires broadcasters, cable television systems, wireless cable systems, satellite digital audio radio service (SDARS) providers and, direct broadcast satellite (DBS) service providers to provide the communications capability to the President to address the American public during a National emergency. The system also may be used by state and local authorities to deliver important emergency information such as AMBER alerts and weather information targeted to a specific area.

The FCC, in conjunction with Federal Emergency Management Agency (FEMA) and the National Oceanic and Atmospheric Administration's National Weather Service (NWS), implement EAS at the federal level. The President has sole responsibility for determining when the EAS will be activated at the national level, and has delegated this authority to the director of FEMA. FEMA is responsible for implementation of the national-level activation of EAS, tests, and exercises. The NWS develops emergency weather information to alert the public of imminent dangerous weather conditions.

The FCC's role includes prescribing rules that establish technical standards for EAS, procedures for EAS participants to follow in the event EAS is activated, and EAS testing protocols. Additionally, the FCC ensures that EAS state and local plans developed by industry conform to the FCC EAS rules and regulations.

[As of 2008-09], the FCC continued to implement its EAS responsibilities in an on-going rulemaking proceeding. In its July 12, 2007 Second Report and Order and Further Notice of Proposed Rulemaking issued in EB Docket 04-296, the FCC addressed various aspects of the current EAS and also explored necessary steps to advance the so-called 'Next Generation EAS.'

The Commission stated that a reliable "wide-reaching public alert and warning system is critical to public safety" and that the EAS network should permit "officials at the national, state and local levels to reach affected citizens in the most effective and efficient manner possible." Among actions taken by the Second Report and Order, the Commission ordered that all EAS Participants must be able to receive messages formatted pursuant to the Common Alert Protocol (CAP 1.1) within 180 days of the adoption of said protocol by FEMA. The Commission also allowed mandatory use of the EAS by a state governor following introduction of CAP, providing that the delivery and transmission of such messages is described in a state EAS plan that is reviewed by the FCC...

Title 47: Telecommunication, Part 11: Emergency Alert System (EAS)

This part [Part 11] contains rules and regulations providing for an Emergency Alert System (EAS).

With the push of a button, the customer's receiver can be used to hear the NOAA simulcast. However, any emergency transmission will override the NOAA broadcast... Interoperability and promoting standards for emergency communications is very important to WSI. Consequently the company is active in several important emergency management and technical associations. We are also proud to have been recognized for contributions to emergency management, interoperability, and community service. WSI regularly participates in joint technology demonstrations utilizing CAP to enable interoperable alert and warning solutions... WSI was chosen to participate in the first pilot phase of FEMA's Integrated Public Alert and Warning System (IPAWS) for CAP based EAS activation, and is under contract to Sandia National Labs to provide EAS and RF activation for phase two of the Web Alert and Relay Network (WARN) pilot portion of IPAWS...

About the EAS-CAP Industry Group (ECIG)

The EAS-CAP Industry Group (ECIG) is a coalition of Emergency Alert System equipment, software and service providers. The EAS-CAP Industry Group is working 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).

The ECIG has been established in response to:

  • A perceived need among EAS industry participants for interoperability among advanced Emergency Alert System (EAS) capabilities in the United States, equipment and services that will map Common Alerting Protocol (CAP) emergency messages into the legacy EAS protocol.

  • A 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 1.1 as a standard for EAS.

  • The need to establish a community and stakeholder process for CAP for the needs of EAS industry participants, including vendors, service providers and broadcasters, cablecasters, wireless cable systems, and satellite program providers.

ECIG Mission Statement:

Using the best available information, the EAS-CAP Industry Group will collaborate to seek agreement on 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 is collaborating to coordinate interoperability data standards among Emergency Alert System equipment, software and service providers. Further, the Industry Group may 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.

In June 2008, "the EAS-CAP Industry Group held its first meeting by teleconference, establishing the overall objectives of the group. ECIG members agreed on the mission of defining an interoperability profile within CAP 1.1 that allows an EAS device to be able to receive a CAP alert from anywhere, and render it into a consistent EAS message. Members at this founding meeting included Digital Alert Systems, Hormann America, Monroe Electronics, MyStateUSA, Sage Alerting Systems, SpectraRep, TFT, and Trilithic."

About the Common Alerting Protocol (CAP)

Common Alerting Protocol Version 1.1. OASIS Standard. Edited by Elysa Jones (Warning Systems, Inc) and Art Botterell. Produced by members of the OASIS Emergency Management Technical Committee. Reference identifier: 'CAP-V1.1'. October 2005. 35 pages. Note that the OASIS Emergency TC is developing several related specifications, including: CAP (Common Alerting Protocol); EDXL-DE (Emergency Data Exchange Language Distribution Element); EDXL-RM (Emergency Data Exchange Language Resource Messaging); HAVE (Emergency Data Exchange Language Hospital AVailability Exchange - HAVE).

"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, thus increasing warning effectiveness while simplifying the warning task. CAP also facilitates the detection of emerging patterns in local warnings of various kinds, such as might indicate an undetected hazard or hostile act. And CAP provides a template for effective warning messages based on best practices identified in academic research and real-world experience.

The Common Alerting Protocol (CAP) provides an open, non-proprietary digital message format for all types of alerts and notifications. It does not address any particular application or telecommunications method. The CAP format is compatible with emerging techniques, such as Web services, as well as existing formats including the Specific Area Message Encoding (SAME) used for the United States' National Oceanic and Atmospheric Administration (NOAA) Weather Radio and the Emergency Alert System (EAS), while offering enhanced capabilities that include:

  • Flexible geographic targeting using latitude/longitude shapes and other geospatial representations in three dimensions
  • Multilingual and multi-audience messaging
  • Phased and delayed effective times and expirations
  • Enhanced message update and cancellation features
  • Template support for framing complete and effective warning messages
  • Compatible with digital encryption and signature capability
  • Facility for digital images and audio

Key benefits of CAP will include reduction of costs and operational complexity by eliminating the need for multiple custom software interfaces to the many warning sources and dissemination systems involved in all-hazard warning. The CAP message format can be converted to and from the 'native' formats of all kinds of sensor and alerting technologies, forming a basis for a technology-independent national and international 'warning internet'...

Applications of the CAP Alert Message: The primary use of the CAP Alert Message is to provide a single input to activate all kinds of alerting and public warning systems. This reduces the workload associated with using multiple warning systems while enhancing technical reliability and target-audience effectiveness. It also helps ensure consistency in the information transmitted over multiple delivery systems, another key to warning effectiveness.

A secondary application of CAP is to normalize warnings from various sources so they can be aggregated and compared in tabular or graphic form as an aid to situational awareness and pattern detection. Although primarily designed as an interoperability standard for use among warning systems and other emergency information systems, the CAP Alert Message can be delivered directly to alert recipients over various networks, including data broadcasts. Location-aware receiving devices could use the information in a CAP Alert Message to determine, based on their current location, whether that particular message was relevant to their users. The CAP Alert Message can also be used by sensor systems as a format for reporting significant events to collection and analysis systems and centers...

History: The National Science and Technology Council report on Effective Disaster Warnings released in November, 2000 recommended that 'a standard method should be developed to collect and relay instantaneously and automatically all types of hazard warnings and reports locally, regionally and nationally for input into a wide variety of dissemination systems'. An international working group of more than 130 emergency managers and information technology and telecommunications experts convened in 2001 and adopted the specific recommendations of the NSTC report as a point of departure for the design of a Common Alerting Protocol (CAP). Their draft went through several revisions and was tested in demonstrations and field trials in Virginia (supported by the ComCARE Alliance) and in California (in cooperation with the California Office of Emergency Services) during 2002 and 2003.

In 2002 the CAP initiative was endorsed by the national non-profit Partnership for Public Warning, which sponsored its contribution in 2003 to the OASIS standards process. In 2004, CAP version 1.0 was adopted as an OASIS Standard..."
