These areas organize P25 CAP Compliance Assessment Bulletins (CABs).
For DHS-authorized accreditation bodies and DHS-recognized laboratories
Laboratory Recognition Conditions and Criteria Agreement (August 2016) — A conditions and criteria agreement signed by laboratories seeking DHS recognition as P25 CAP laboratory. A prerequisite is a P25 CAP accreditation in accordance with the polices of the DHS-authorized accreditation body the laboratory selects.
Accreditation Body Authorization Conditions and Criteria Agreement (December 2014) — A conditions and criteria agreement signed by DHS-authorized accreditation bodies to operate the P25 CAP accreditation program.
P25 CAP Defining Documents
P25 CAP Minimum Feature Requirements (November 2017) — Defines the minimum interoperability features and capabilities required for P25 subscriber and repeater equipment capable of conventional operation to be eligible to be considered P25 CAP Compliant.
P25 CAP Encryption Requirements (March 2017) — Provides the encryption requirements for P25 CAP and an accompanying comment matrix.
To request the editable version of any SDOC template in Microsoft Word with built-in 508-compliance attributes defined or STR template in Microsoft Excel, please contact P25CAP@hq.dhs.gov.
Supplier’s Declaration of Compliance (SDOC) Requirements (2018) — Identifies uniform format requirements for use in preparation of SDOC documents. These documents are submitted to DHS for review and approval. Once approved, SDOC documents can be viewed publicly at the P25 CAP Approved (Grant-Eligible) Equipment page of this site.
Summary Test Report (STR) Requirements (2018) — Identifies uniform format requirements for use in preparation of STR documents. These documents are submitted to DHS for review and approval. Once approved, Summary Test Reports can be requested via email (P25CAP@hq.dhs.gov).
Baseline Common Air Interface Testing Requirements (October 2018) — Applies to P25 Subscriber Equipment, Repeater, and Base and Fixed Station products. Update to the p2017 Common Air Interface Compliance Assessment Bulletin (CAB). This CAB eliminates some test cases for subscriber direct interoperability testing, subscriber repeat interoperability testing and base station repeat interoperability. It also removes the requirement to report 700MHz Adjacent Channel Power Ratio test case results, as the 700MHz Adjacent Channel Power Ratio test results were submitted for FCC equipment authorization
ISSI/CSSI Interoperability Testing Requirements CAB, Revision 2 (June 2021) — This document replaces the previous ISSI/CSSI Interoperability Test Requirements CAB (October 2019) to add a new Appendix B. This CAB lists interoperability test cases for the P25 Console Subsystem Interface (CSSI) and the P25 Inter-RF Subsystem Interface (ISSI).
ISSI/CSSI Conformance Testing Requirements CAB (December 2020) — This document replaces the Baseline Inter-Radio Frequency Subsystem Interface (ISSI) and Console Subsystem Interface (CSSI) Conformance Testing Requirements (May 2019) CAB. P25 CAP ISSI/CSSI Conformance testing validates the protocol and messages that are exchanged across a P25 wireline interface.
Additionally, we have updated related documents including the ISSI/CSSI Conformance Pass/Fail Criteria document and all of the following ISSI/CSSI Conformance Test Case Documents:
- ISSI-RFSS Conformance Test Case Doc (DEC 2020)
- CSSI-RFSS Conformance Test Case Doc (DEC 2020)
- CSSI-CSS Conformance Test Case Doc (DEC 2020)
To review any of the ISSI/CSSI Conformance Test Case documents listed above, please contact P25CAP@hq.dhs.gov to receive it via email.
Compliance Testing Rules (October 2019) — Provides rules for the application of the different Common Air Interface (CAI) CAB versions.
P25 ISSI/CSSI Conformance Test Tool Validation (August 2023) - The purpose of this document is to clearly convey the procedures, requirements, and guidance used by the Department of Homeland Security Science & Technology (DHS S&T) P25 Compliance Assessment Program (P25 CAP) for approving and recognizing an Inter-subsystem interface/Console sub-system interface (ISSI/CSSI) Conformance Test Tool (ICCTT) for the conduct of the P25 Compliance assessment.
Testing Requirements (November 2023) - This document defines various aspects of P25 CAP, including new Participating Equipment Manufacturer Requirements to maintain equipment on the Approved (Grant-Eligible) Equipment list that will help ensure the accuracy of equipment on the list. In addition, this document outlines Interoperability Testing and Retesting Requirements for Common Air Interface equipment.
Baseline Inter-Radio Frequency Sub-System Interface and Console Sub-System Interface (ISSI/CSSI) Conformance Testing Requirements (May 2019) — P25 CAP ISSI/CSSI Conformance testing will validate the FNE equipment under test portion of the SIP, SDP and RTP messages that are exchanged during specific test cases between the FNE equipment under test and the conformance test tool. The conformance test tool solution enables conformance testing of these interfaces in the P25 public safety network. The test tool simulates RFSSs, console subscriber units and mobile subscriber units to test FNE equipment with the P25 ISSI/CSSI interfaces
Baseline Common Air Interface Testing Requirements (July 2017) — Applies to P25 Subscriber Equipment, Repeater, and Base and Fixed Station products and includes Time Division Multiple Access (TDMA) testing requirements.
DHS Consolidated Comments Matrix (December 2020): The ICC Test Tool Verification CAB was finalized after a 30 day public comment period. The DHS Consolidated Comment-Resolution Matrix details all comments received as well as resolution details for each.
P25 CAP provides the public with an opportunity to review and comment on Compliance Assessment Bulletins and reporting templates before they are finalized and published. All comments received are adjudicated and addressed, and are available for review.
