P25 Steering Committee, CISA release P25 resource

The P25 Steering Committee, with support from the US Government’s Cybersecurity and Infrastructure Security Agency (CISA), has developed the Statement of Project 25 User Needs (SPUN) to help users better understand P25 technologies and identify their communications needs.

According to Jim Downes, CISA Branch Chief, “Most LMR users lack both access to the P25 Standards and the time to read through volumes of technical documentation to fully grasp all the features and capabilities that P25 systems can provide or to engage in the standards development process.”

The SPUN provides high-level explanations of P25 system architecture, features and functions as defined in the Telecommunications Industry Association 102 Suite of Standards (P25 Standards) and recognised by P25 users and system administrators.

The SPUN is divided into two sections:

• P25 Overview (Main Document), covering P25 general features, functions and services; interfaces; system types and modes; and system components.
• P25 User Needs List (Appendices), covering specific user needs across different system modes (ie, trunking and conventional) and user needs for different P25 interfaces.
   

The SPUN translates the more than 70 P25 Standards into relatable content to help public safety agencies understand all the capabilities available to them through the standards.

It also provides a way for users to know if the standards can address their unmet needs and how to frame their input to the P25 Steering Committee.
