P25 Standards Update January 2022

DHS CISA publishes a new guide for Emergency Alarm across Multiple P25 Systems

Project 25 Inter-RF Subsystem Interface and Console Subsystem Interface Features and Functions

The DHS Cybersecurity & Infrastructure Security Agency (CISA) recently published a new guide to inform the P25 User Community about important considerations when applying the Emergency Alarm Function across multiple P25 Systems using the ISSI/CSSI.

The document can be downloaded using the link below:

https://www.cisa.gov/sites/default/files/publications/21_1025_fpic_p25_issi-cssi-features-and-functions_emergency-alarm-call_508c_0.pdf

This document is part of a series of Project 25 (P25) Inter-Radio Frequency (RF) Subsystem Interface (ISSI) and Console Subsystem Interface (CSSI) Features and Functions write-ups designed to increase awareness of P25 features, terminology, and implementation considerations learned during ongoing discussions within the Federal Partnership for Interoperable Communications (FPIC) ISSI/CSSI Focus Group. The document uses vendor neutral P25 Standards terminology, but the reader should be aware that different manufacturers and user communities often use different terms to describe these features.

Harmonized radio behavior and interoperability across multi manufacturer implementations is the goal for Emergency Alarm operations. It should be noted that the issues identified in the guide occur only in specific combinations of manufacturers equipment and in specific conditions. Therefore, they are often difficult to identify and resolve due to their level of complexity and the number of permutations that exist. Additionally, existing implementations conform with the current P25 standards; as such, issues can only be identified through extensive interoperability testing and/or during live operations.

DHS CISA releases a New Project 25 Video:

“The Funding and the Future of P25”

The Project 25 Technology Interest Group is pleased to offer a link to the latest P25 Video from DHS Cyber Security & Infrastructure Security Agency (CISA)

“The Funding and the Future of P25” is an overview of the value and advantages of Project 25 (P25) as a long-term investment in a community’s public safety.

The video can be accessed using the link below:

https://www.youtube.com/watch?v=Hq5CozWWFN4

DHS CISA Website Overview:

“Presented through interviews of emergency communications practitioners and managers nationwide, the six-minute video focuses on the features and comparative costs of P25 standards-based systems versus non-P25 systems, the practical value of P25 technology in public safety operations, and recommendations for funding P25. Looking ahead, the presenters discuss the current states of P25 and long-term evolution (LTE) broadband technology, emphasizing the durability, transmitting power, one-to-many communication, and emergency push-to-talk features of P25 radios. Their conclusion: P25 and LTE are not exclusive options but likely complimentary components of public safety communications in the future.”

Key Messages from the Video:

• Project 25 is a great value for Public Safety.
• A Multi-vendor market drives competition.
• P25 Sharing = Cost Savings.
• Grant Funding is available.
• P25 LMR is here to stay for the foreseeable future.
• P25 works when the network is down. Direct mode is important to public safety.
• P25 “One to Many” PTT comms are essential to Users.
• Agencies need to prioritize continued funding and development for P25 technology.
