U.S. Department Of Homeland Security Conducts ISSI / CSSI Testing Under P25 Program

Date:Nov 28, 2019



The US Department of Homeland Security (DHS) announced the Project 25 (P25) Standard Compliance Assessment Program (CAP), adding Inter-RF subsystem interface and console subsystem interface (ISSI / CSSI) equipment. The extension allows testing of interoperability of P25 ISSI / CSSI equipment through accredited laboratories.

The Department of Homeland Security's Science and Technology Agency (S & T) is working to authorize laboratories to conduct testing. American Laboratory Accreditation Association (A2LA) and ANSI National Accreditation Board (ANAB)-both DHS accredited certification bodies that provide on-site assessment of test laboratories as part of the P25 standard-now ready to test ISSI / CSSI interoperability Testing laboratory for certification.

Once laboratories are accredited by their respective accreditation bodies, they can test manufacturers' ISSI and CSSI equipment for compliance with the interoperability requirements of the P25 standard.

S & T issued a Compliance Assessment Bulletin (CAB) earlier this year outlining test requirements for ISSI / CSSI interoperability and ISSI / CSSI compliance. The next step in the certification of the laboratory for ISSI / CSSI interoperability testing brings the program closer to being able to incorporate ISSI / CSSI equipment into its approved equipment, which can be purchased through government funding.

When the supplier completes a set of tests, DHS will publish the test results on the "ISSI / CSSI device ongoing testing" page. When the supplier successfully completes the two sets of interoperability and conformance tests, DHS will post the complete results in the "Approved (Eligible) Equipment List" on the P25 standards website.

S & T is validating ISSI / CSSI compliance testing tools and expects certified laboratories to be ready for compliance testing by spring 2020. At the same time, S & T is also collaborating with multiple suppliers to pilot their CSSI and ISSI equipment for independent tool verification and validation, and to reduce procedural risk.

In addition, the US Department of Homeland Security's approval from the Office of Management and Budget's Reduced Paperwork Act expired on June 30, resulting in the temporary inability to issue compliance statements for suppliers of P25 products. However, DHS determined that the number of manufacturers in the P25 product market caused SDOC / Summary Test Report collection to be non-compliant. Upon confirmation from the Office of the Chief Information Officer of DHS, S & T can publish the submitted SSC again and provide the STR upon receiving an email request.

S & T is updating all P25 standard templates to remove the burden statement from the U.S. Administration and Budget. For SDOC / STR submissions submitted before June 30 and currently posted on the "Approved (Eligible) Devices" webpage, no further action has been taken until these test documents will be updated. DHS will not make any changes to these files.

As more manufacturers may enter the market in the future, S & T will continue to seek permits to make the P25 standard compliant in this case.
