P25 Steering Committee and CISA release Statement of Project 25 User Needs

Jim Downes, Cybersecurity and Infrastructure Security Agency (CISA), Branch Chief

To help Project 25 (P25) users navigate the continuing evolution of P25 systems and the complex world of P25 Standards, the P25 Steering Committee, with support from CISA, developed the Statement of Project 25 User Needs (SPUN) as a framework for users to better understand P25 technologies and define their communications needs.

CISA at 2019 APCO: Day 1

APCO 2019, APCO International’s Annual Conference and Expo, is the premier event for public safety communications officials, from frontline telecommunicators to communications center managers to public safety communications equipment and services vendors.

ISSI and CSSI Implementation Guidance

The Federal Partnership for Interoperable Communications (FPIC), in conjunction with SAFECOM and the National Council of Statewide Coordinators (NCSWIC), has published a guidance document for the emergency communications user community concerning implementation of Project25 (P25) Inter-RF Subsystem Interface (ISSI) and Console Subsystem Interface (CSSI) technologies.

 

ISSI and CSSI Implementation Guidance Document Now Available

The Federal Partnership for Interoperable Communications (FPIC), in conjunction with SAFECOM and the National Council of Statewide Coordinators (NCSWIC), has published a guidance document for the emergency communications user community concerning implementation of Project25 (P25) Inter-RF Subsystem Interface (ISSI) and Console Subsystem Interface (CSSI) technologies.

As the public safety community continues to recognize the importance of land mobile radio (LMR) operability and interoperability, interest in ISSI and CSSI technology has increased. Given this heightened interest in both technologies, the FPIC developed an ISSI/CSSI User Focus Group to:

  • Explore the ISSI/CSSI technology offerings;
  • Document successful deployments, existing challenges, and impediments to deployments;
  • Illustrate the complexities of ISSI/CSSI implementations; and
  • Identify actionable solutions for addressing implementation challenges.

The ISSI/CSSI User Focus Group developed the Best Practices for Planning and Implementation of P25 Inter-RF Subsystem Interface (ISSI) and Console Subsystem Interface (CSSI): Volume I to address pre-planning, partnerships, and governance practices that are essential for planning an ISSI and/or CSSI implementation. The document—which is the first in a series of “best practices” documents—includes a one-page “Best Practices Checklist,” incorporating important steps such as developing a thorough understanding of what ISSI- and CSSI-enabled systems can and cannot do, and coordinating ISSI governance with existing systems management and governance. Volume 1 also details benefits of interoperability enhancements and the potential for infrastructure sharing through an ISSI/CSSI for those agencies interested in implementing either or both technologies.

The best practices contained in Volume 1 are an extensive collaborative effort of the FPIC ISSI/CSSI User Focus Group, which primarily consists of non-federal (state and local) public safety entities. The Joint SAFECOM-NCSWIC Technology Policy Committee also reviewed and approved the document prior to approval by the SAFECOM and NCSWIC Executives Committees (ECs).

The Best Practices for Planning and Implementation of P25 Inter-RF Subsystem Interface (ISSI) and Console Subsystem Interface (CSSI): Volume I document is available at www.dhs.gov/technology. For those interested in learning more about ISSI and CSSI implementation, or for those interested in FPIC-related activities, please visit www.dhs.gov/safecom/fpic for more information.

Technology

Technology is a critical tool for improving interoperability that should meet the needs of practitioners on the front lines and should address regional needs, existing infrastructure, cost verses benefits, and sustainability. The resources below provide examples of the technology currently used in the public safety environment.
