News Release: DHS S&T Showcases Tech Advances at IWCE 2019

WASHINGTON – The deadline for submitting comments on the Project 25 Compliance Assessment Program (P25 CAP) draft Compliance Assessment Bulletin (CAB)  has been extended to March 31. Issued by the U.S. Department of Homeland Security (DHS) Science and Technology Directorate (S&T), this draft CAB addresses P25 Baseline Inter-Radio Frequency Sub-System Interface (ISSI) and Console Sub-System Interface (CSSI) Conformance Testing Requirements.

This bulletin expands the P25 CAP’s testing scope to allow a more diverse set of equipment becoming a part of the program.

Project 25 (P25) is a suite of standards that enables interoperability among digital two-way land mobile radio (LMR) and standardizes interfaces between the various components of the LMR systems that first responders use. P25 CAP is a voluntary program that allows communications equipment manufacturers to publicly attest to their products’ compliance through testing at DHS-recognized laboratories. All approved equipment is eligible to be purchased using federal grant funding.

After the comment period, DHS S&T will review comments, incorporate feedback, as appropriate, and finalize the CAB. The final CAB and adjudicated comments will be posted to the P25 CAP website. For more information, visit
