The New Primer offering a comprehensive overview of the P25 Inter-RF Subsystem Interface (ISSI) and Console Subsystem Interface (CSSI) is now available and can be downloaded off the PTIG as well as DHS websites.

This document’s purpose is to introduce the Inter-RF Subsystem Interface (ISSI) and Console Subsystem Interface (CSSI) technologies and highlight potential benefits and uses, discuss the existing Project 25 (P25) LMR standards that govern the technologies, briefly introduce some of the challenges associated with the implementation of the standards, and discuss how best to address these challenges in the future.

The document was developed by SAFECOM, The Federal Partnership for Interoperable Communications (FPIC) and the National Council of Statewide Interoperability Coordinators (NCSWIC)

The document provides a high-level overview of a broad range of introductory topic areas relevant to ISSI and CSSI, including:

  • •Overview of ISSI/CSSI technology,
  • •Benefits of ISSI/CSSI,
  • •How Project 25 standards address ISSI/CSSI,
  • •ISSI/CSSI planning and implementation challenges,
  • •Resources for effective ISSI/CSSI implementation, and
