Project 25 Documents & Standards Reference

Revised Jan 18, 2012

Compliance Assessment Program

The P25 CAP (Project 25 Compliance Assessment Program) provides emergency response agencies with evidence that the communications equipment they are purchasing meet P25 (Project 25) standards for performance, conformance, and interoperability. Equipment suppliers can participate in the voluntary program to formally demonstrate their products’ compliance with a select group of requirements within the P25 suite of standards. The program requires test laboratories to demonstrate their competence through a rigorous and objective assessment process. Such a process promotes the user community's confidence in, and acceptance of, test results from recognized laboratories.

All equipment suppliers that participate in the P25 CAP must use recognized laboratories to conduct performance, conformance, and interoperability tests on their products. Those who participate submit SDoC (Supplier’s Declaration of Compliance) documents and Summary Test Reports to the RKB (Responder Knowledge Base) web site (https://www.rkb.us/) for DHS/OIC (Department of Homeland Security/Office for Interoperability and Compatibility) review and approval of eligibility for grant procurement. The following documents provide more information about the P25 CAP.

  • Charter for the Project 25 Compliance Assessment Program (Apr 2008)

  • The P25 CAP charter outlines the roles and responsibilities of the parties involved in the P25 CAP program. It includes an overview of the program including what is required of testing laboratories, vendors, and other participants.

  • Compliance Assessment Requirements (Mar 2010)

  • This document provides the requirements for the P25 CAP, including an overview of the P25 interfaces that are currently covered by the P25 CAP, and when the applicable SDoC documents and Summary Test Reports are required.

  • Supplier’s Declaration of Compliance Requirements (Sep 2009)

  • This CAB (Compliance Assessment Bulletin) identifies uniform format requirements for use in preparation of SDoC documents. These documents are submitted to the RKB for DHS/OIC review and approval.

  • Summary Test report Requirements (Sep 2009)

  • This CAB identifies uniform format requirements for use in preparation of Summary Test Report documents. These documents are submitted to the RKB for DHS/OIC review and approval.

Once approved, SDoC documents and associated Summary Test Reports can be viewed publicly at the RKB. Follow these steps to view approved SDoCs and associated Summary Test Reports at the RKB:

  1. Go to the Certifications and Declarations page of the RKB.

  2. Click P25 SDoCs in the left column.

  3. Click the title of the supplier’s equipment for which you want to view declaration information.

  4. At the bottom of the page under Additional Information, click the SDoC and Summary Test Report links.

Performance, conformance, and interoperability issues are likely to occur in all communications technologies and especially in ones like P25 with protocols that constantly adapt to changing user requirements. Such problems should be resolved within the P25 CAP, and notably, before product launch and deployment. Further, the declaration of compliance-related documents developed by program participants will provide useful technical information about the equipment.

The P25 CAP will provide emergency response agencies nationwide with a consistent and tractable perspective of P25 product compliance. It will also provide a means of verifying that Federal grant dollars are being invested in standardized solutions and equipment that promotes interoperability.
