CISA Video: Basics of P25

By: Jim Downes, P25 Steering Committee Chairman

One only has to talk with public safety personnel who routinely use P25 to get a real sense of its value to communities nationwide. A new five-and-a-half minute CISA video—” Basics of P25”—does just that. Through interviews with responders, communications managers and engineers, emergency operations managers, and Statewide Interoperability Coordinators (SWICs) from across the Nation, the video covers:

  • P25’s role in public safety
  • Its value in both daily operations and emergencies involving mutual aid partners and outside agencies
  • Its advantages for enhancing personnel safety and operational efficiency
  • Cost savings it offers communities, and
  • Practical recommendations for planning and implementing a P25 radio system.

For agencies considering a P25 system, the video offers a clear, practical overview of the technology’s ever-increasing role in law enforcement, fire, and emergency medical organizations and a foundation for exploring P25 in greater detail through CISA’s and SAFECOM’s library of P25 documents.


CISA Video: Encryption in Three Minutes

Drawn from interviews with emergency communications practitioners nationwide, “Encryption in Three Minutes” presents an overview of LMR and P25 encryption in public safety operations. The video outlines encryption’s role in protecting sensitive tactical and operational communications as well as the personal identifiable information and medical status of civilian patients during emergencies. Discussion focuses on implementing a practical, reliable encryption system while preserving interoperability with mutual aid partners and outside agencies. Special attention is given to selecting the most secure encryption algorithm. It is an ideal brief overview of LMR encryption aimed at community leaders and public safety administrators, officials, and responders.

Project 25 Standards Update: February 2021 presented at the P25 Steering Committee Web conference.


Andy Davis, Chairman, TIA TR-8 Committee

This document highlights TR-8 accomplishments and work in progress for The Project 25 Suite of Standards in 2021. The document will be updated after every TR-8 face to face meeting and at a regular intervals during the COVID period when face to face meetings have been discontinued.  The filename reflects the date of the latest update.

After the first 2021 version, each update will use blue font to indicate the updates.

Zetron-Motorola Solutions CSSI Interoperability Testing

Testing was completed during the week of January 4, 2021. 

The full report can be downloaded using the link directly below: 

Zetron-Motorola Non CAP CSSI Interoperability Test January 2021


Testing Configuration Info:

  • Motorola Solutions lab connected to Zetron lab via VPN. Intra System configuration (i.e. matching WACN ID + System ID)
  • The Motorola RF Subsystem (RFSS) was configured as the ""Home"" subsystem for all talkgroups used in the testing.
  • The Zetron Console Subsystem (CSS) was configured as the ""Serving"" subsystem for all talkgroups used in the testing and consisted of console equipment only. "
  • MSI software versions: ISGW-Astro-
  • Zetron software versions:ACOM Novus ASB57


Non CAP Interoperability Testing Background

Manufacturers have been doing lab to lab testing of commonly supported ISSI/CSSI standard feature sets for some time now.

A template is available defining a method for reporting ISSI and/or CSSI P25 Interoperability testing results outside CAP.

At the time of this template’s publication, there were no ISSI or CSSI testing results available yet from the DHS OIC Compliance Assessment Program (CAP)

The template allows reporting on interoperability of testing equipment from two manufacturers. That testing may have been performed in a single lab, in a lab to lab setting or in an installed customer setting. That testing may have been performed by personnel with or without ISO/IEC 17025 recognition.

The template does not intend to prescribe a list of standard functionality that could or should be tested. The functionality covered by a published report should be determined by the manufacturers completing the report.

The Project 25 Consolidated Communications Network of Colorado (CCNC) proves to be a Game-Changer for multi-agency coordination as well as preserving life safety during the recent 2020 wildfires in the state.

By: Sheriff Justin Smith, Larimer County Colorado


PTIG Thanks Sheriff Smith for this excellent story and poictures depicting the use of Project 25 for Interopreability and multi-agency coordination during the 2020 wildfires in Colorado.  Please download the full story using the link below.

Colorado P25 CCNC Game Changer for Interoperability in 2020 Wildfires Dec 2020


Larimer County P25 interoperability During 2020 Wildfires

With shared talkgroup access between first responder agencies and several locally established mutual aid paths to facilitate regional shared communications, agencies across Larimer County have grown to depend on the communications made possible under the P25 standards.

However, beginning on August 13 of 2020, we tested the limits of the system and enjoyed the benefits of a statewide P25 system when we organized our response to the Cameron Peak Fire- a Rocky Mountain wildfire that over the following 3 months grew into Colorado’s largest single wildfire on record.

Once the response grew beyond county-based agencies, Larimer County requested and received permission to secure a regional mutual aid channel (MAC) under the CCNC system. Having access to that MAC assured that any first responder agency in the state who sent resources could immediately be in communications with local resources without having to issue cache radios or reprogram radios brought by those first responders.

That capability proved a game changer for coordination as well as preserving life safety throughout the fire.

Assisting resources from around the state were advised of the communications plan prior to arrival and we able to communicate with Larimer County agencies seamlessly.
