Minimum Feature Requirements Compliance Assessment Bulletin – Published

November 13, 2017 -- The Minimum Feature Requirements Compliance Assessment Bulletin (CAB) is now finalized and can be accessed on the P25 CAP Bulletins page. Thank you to all those who have submitted their comments. There is an accompanying comment matrix that is also published outlining the comments received. The Minimum Feature Requirements CAB defines the minimum interoperability features and capabilities that are required for P25 subscriber and repeater equipment that are capable of conventional operation to be eligible to be considered P25 CAP Compliant. This document defines which Telecommunications Industry Association (TIA)-102/P25 CAP conventional interoperability test cases shall be passed in order for the equipment to be eligible to be considered P25 CAP Compliant and for the equipment’s SDOC and STR to be eligible for posting on the P25 CAP Approved (Grant Eligible) Equipment page.

Industry Response to Encryption Requirements CAB

November 2, 2017 -- Earlier this year, DHS OIC published the Encryption Requirements Compliance Assessment Bulletin (CAB), which outlines P25 CAP requirements for encryption. The Encryption Requirements CAB resulted in some manufacturers’ equipment no longer being identified as P25 CAP Compliant. Since then, all affected manufacturers have engaged with DHS OIC to identify the process for bringing their equipment into compliance with the Encryption Requirements CAB and have done so. Each piece of equipment currently found on the Approved (Grant-Eligible) Equipment page is P25 CAP Compliant. 

DHS OIC, with permission from each manufacturer, is making the correspondence received available. The manufacturers’ correspondence explains, in each manufacturer’s own words, the process each manufacturer is using to bring its equipment into compliance with the Encryption Requirements CAB and the process each manufacturers’ customers would follow to ensure the equipment they are going to purchase or have already purchased would be or would be made P25 CAP Compliant.

2016 CAB Exception for Conventional Interoperability with Dispatch Console Testing

August 28, 2017 -- Until February 28, 2018, DHS OIC is granting an exception for “rule of three” conventional interoperability testing for specific test cases. This exception is being granted due to delays in getting a sufficient number of P25 Test Labs accredited for conventional interoperability testing. The test cases receiving the exception are in Table 16. Conventional Interoperability Tests – FNE Includes Dispatch Consoles Mode of the Project 25 Compliance Assessment Program Baseline Common Air Interface Testing Requirements (P25-CAB-CAI_TEST_REQ  August 2016).

For the equipment submitted under this exception, DHS OIC will add a note on the P25 CAP web page that states the equipment was submitted with an exception for Conventional Interoperability with Dispatch Console testing.

The SDOC that is submitted shall state in the P25-CAB-CAI_TEST_REQ – AUGUST 2016, Section 2.1.3.2 paragraph: “Conventional Interoperability Tests – FNE Includes Dispatch Consoles Mode testing was not completed when submitted.”

The STR that is submitted shall display a test case result of ‘E’ for all test cases where the exception is being claimed for the test cases listed under INTEROPERABILITY TESTING (700 MHZ, 800 MHZ) – CONVENTIONAL FNE INCLUDES DISPATCH AND OTHER MONITORING CONSOLES (REPEAT MODE (SU-TO-FNE-TO-SU) OR DIRECT MODE).

A new comment row shall be added in the STR Comments table. The row shall state “E: Exception to Conventional Interoperability Tests – FNE Includes Dispatch Console Mode”.
