New PTIG Whitepaper: What is P25 Compliance?

This paper is intended to explain different levels of compliance statements that may be used by customers or consultants when specifying an equipment purchase or used by manufacturers promoting equipment capabilities.

In general, “Project 25 (P25) compliance” is typically interpreted as: “adherence to the P25 standard”.

The P25 Standard is composed of over 80 documents that cover multiple interfaces, multiple services and multiple features associated with each interface or service. Therefore, questions or statements about compliance to the “P25 standard” are really too vague to provide the understanding typically desired by those asking the questions or making the statements. Questions or statements about any level of compliance are more effectively expressed in the context of a specific interface, a specific service or a specific feature that is covered by a published P25 standard document or in the context of a specific standard document. For example, the statement: “My equipment is P25 compliant” is difficult to correctly interpret because it does not identify any P25 standard interface or service or document or set of features. A better statement would be along the lines of: “My radio is compliant to the P25 FDMA Air Interface, Trunking service, Group Voice Call feature.”

Four levels of assessing compliance are commonly used and are discussed in the Whitepaper. The P25 user and manufacturer community should use the four levels of compliance when referring to the requirements or capabilities of P25 products, features and services.

ISSI/CSSI Non-CAP Interoperability Testing Template  January 2019

P25 Manufacturers have been doing lab to lab testing of commonly supported ISSI/CSSI standard feature sets for some time now.

This template describes 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 PTIG P25 Capabilities Guide may be used as a reference for P25 features and testing methods included in published P25/TIA-102 standard documents.

PTIG P25 Update for IACP Communications and Technology Committee October 2018

 
The Department of Homeland Security Office of Emergency Communications (OEC) and the Project 25 (P25) Steering Committee sponsored a P25 Executive Summit in Portland, Oregon, May 16 and 17, 2018. Leaders from P25 public safety user agencies at all levels of government and the P25 vendor community were invited to address P25 Land Mobile Radio (LMR) user concerns. Topics included P25 LMR interoperability successes and challenges and opportunities to collaborate to ensure the future sustainment of critical LMR capabilities.
 
This two day event included an opportunity for the user community to share concerns and lessons learned, and identify topics on specific agenda items to discuss with manufacturers as the Summit progressed. On the second day, both users and vendors met to address key P25 issues and concerns from both the user and manufacturer perspectives and develop collaborative approaches to effectively address the improving and sustaining LMR capabilities.
 
GOALS AND OBJECTIVES
The primary goals and objectives of the Summit were to provide participants with a better understanding of how the P25 user community and the vendor community can develop an enhanced dialog outside of marketing pressures to resolve the challenges that face public safety, specifically to:
 
 Address how disparate systems and manufacturers’ interpretations of the standards can negatively impact interoperability
 Develop a process that will lead to an environment where all P25 compliant equipment, regardless of make or model, are interoperable upon delivery
 Articulate the importance of interoperability and critical activities to improve user-to-user communications and user-to-vendor interactions
 Obtain commitments from participants to support identified actions
