P25 compliant, P25 CAP compliant, P25 compliant with the Statement of Requirements (P25 SOR) -- what does it all mean?

P25 CAP, a voluntary program, allows suppliers to publicly attest to their products' compliance through P25 CAP testing at DHS-recognized laboratories. As proof, suppliers are required to submit Summary Test Report (STR) and Supplier’s Declaration of Compliance (SDOC) documents. These documents are available on the Approved (Grant-Eligible) Equipment page. It is this list, and only this list, which is referenced by several federal grant programs, including the Federal Emergency Management Agency, as allowable equipment to be purchased. The varying P25 labels can be confusing, and our guide on P25 terminology explains the program and how the terms apply.

    Program Updates

    P25 Accreditation Bodies Ready for ISSI/CSSI Interoperability

    November 18, 2019 -- P25 CAP is officially incorporating ISSI/CSSI equipment as part of its program.

    Two DHS-recognized accreditation bodies – the American Association for Laboratory Accreditation (A2LA) and ANSI National Accreditation Board (ANAB) – are ready to accept requests from testing laboratories to be accredited for ISSI/CSSI Interoperability testing. Once the laboratories are accredited by their respective accreditation body, they will be able to test manufacturers’ ISSI and CSSI equipment to P25 CAP’s interoperability requirements.

    As vendors complete one set of tests (e.g., Interoperability), DHS will post test results on an “ISSI/CSSI Equipment Testing in Progress” page. Once vendors successfully complete both sets of tests for Interoperability and Conformance, DHS will publish completed results in the Approved (Grant-Eligible) Equipment List on the P25 CAP website. S&T is currently validating an ISSI/CSSI Conformance testing tool and anticipates that an accredited laboratory should be ready for Conformance testing by spring of 2020. For questions on accreditation and testing, or to participate in pilots with vendors of CSSI and ISSI equipment for independent validation and verification of tools, please contact P25CAP@hq.dhs.gov.

    Past Events and Announcements

    Baseline ISSI/CSSI Interoperability CAB and Templates Published

    October 16, 2019 -- The Baseline Inter-Radio Frequency Sub-System Interface and Console Sub-System Interface (ISSI/CSSI) Interoperability Testing Requirements Compliance Assessment Bulletin (CAB) and accompanying Supplier’s Declaration of Compliance (SDOC) template have been published. We appreciate the input we received during the public comment period and have also published public comment tables with the comments and our responses. For a copy of the Summary Test Report (STR) template, please contact P25CAP@hq.dhs.gov.

    Testing Rules CAB Published

    October 9, 2010 -- DHS S&T has issued multiple P25 CAP Common Air Interface (CAI) Testing Requirements CABs. This Testing Rules CAB provides rules for the application of the different CAI CAB versions. We are currently developing rules for the application of the ISSI/CSSI CABs. For any questions, exceptions or waivers to these testing rules, please contact P25CAP@hq.dhs.gov.

    P25 CAP AP Task Force now under SAFECOM

    September 5, 2019 -- DHS has moved the P25 CAP Advisory Panel (AP) under the SAFECOM governance structure, which is managed by the DHS Cybersecurity and Infrastructure Security Agency (CISA). This transition provides P25 CAP activities with a broader audience via SAFECOM users and leverages the legislative authority that SAFECOM maintains in support of emergency communications. The current AP membership will remain the same with the P25 CAP AP Task Force (TF). This transition only involves the AP changing to a SAFECOM TF. There are no changes to P25 CAP at large, which remains under DHS S&T.

    About P25 CAP

    The P25 CAP is a partnership of the U.S. Department of Homeland Security’s Science and Technology Directorate, SAFECOM, industry and the emergency response community. The initial program focus is on the Common Air Interface, which allows for over-the-air compatibility between radios and tower equipment. While P25 CAP testing is not currently available for ISSI/CSSI, DHS S&T is working with the Department of Interior to establish an ISSI/CSSI test lab and formalize test procedures to include as part of P25 CAP.

    For more information on P25 CAP, watch the video and read the following overview documents listed below:

    • The Project 25 Compliance Assessment Program (P25 CAP) establishes standards and compliance test protocols for ensuring the interoperability of the digital communications equipment emergency responders use. The P25 CAP video highlights the P25 CAP Advisory Panel’s efforts to review, evaluate and update the standards to keep pace with advances in digital communications.
    • The P25 CAP Compliance: What Should it Mean to You? document provides definitions for common P25 terminology.
    • The P25 CAP Fact Sheet describes how the P25 CAP works, the value of the program to public safety, and the program’s long-term-goals.
    • The P25 CAP Charter provides an overview of the program, the program’s operating framework, and the roles and responsibilities of the involved parties.
    • The P25 CAP FAQs document addresses commonly asked questions about the program.

    P25 CAP activities are supported by Congress.

    The Intelligence Reform and Terrorism Prevention Act of 2004 established the Office for Interoperability and Compatibility (OIC) within the S&T Directorate to carry out responsibilities and authorities relating to the SAFECOM Program. The DHS Appropriations Act of 2007 refined and expanded the authorities of OIC within S&T to: support the creation of national voluntary consensus standards for interoperable emergency communications; establish a comprehensive research, development, testing and evaluation program for improving interoperable emergency communications; and encourage more efficient use of existing resources, including equipment, to achieve interoperable emergency communications capabilities.
