There were 194 New P25 Trunking Systems Identified since the list was last published in 2017. Other major trends include a strong migration from P25 Phase 1 to P25 Phase 2 Systems. P25 Phase 1 Systems are down from 728 systems to 652 Systems while Phase 2 systems are up from 188 to 364 known systems. In addition, 93 P25 Systems have been merged or consolidated into larger Regional or State-wide P25 systems and are no longer listed as stand-alone systems. The net total with consolidations removed is up 101 systems from the 2017 list.
P25 Conventional Systems are found on a separate list on the PTIG website. There are 1334 Conventional Systems on that list. The grand total of P25 Systems both Conventional and Trunking is 2351.
The P25 Trunking System List Includes System Name, P25 Phase 1 or P25 Phase 2, Primary User designation, Statewide System Designation, and the Frequency Band in use.
Public Safety remains the primary user type with DoD and Federal Agencies being the other primary user Groups. Additional P25 systems were recognized for Public Works, Utilities, Corrections (non Federal), Business, Airport/Transportation, and Universities. There are 37 Statewide P25 Trunking Systems recognized.
Frequency Bands in use remain dominated by 800 MHz, 700 MHz and UHF LO (380-420 MHz).
PTIG Publishes New P25 ISSI/CSSI Best Practices Guide from FPIC/SAFECOM/NCSWIC
Details
The Project 25 Technology Interest Group (PTIG) is pleased to publish a new Best Practices for Planning and Implementation of P25 Inter-RF Subsystem Interface (ISSI) and Console Subsystem Interface (CSSI): Volume I. This document is a result of an extensive collaborative effort of the Federal Partnership for Interoperable Communications (FPIC) ISSI/CSSI Focus Group supported by supported by the Department of Homeland Security Cybersecurity and Infrastructure Security Agency Emergency Communications Division.
Executive Summary
Project 25’s (P25) open standards define features and functions and the interfaces of P25-compliant radio systems. Two of these interfaces, the Inter-RF Subsystem Interface (ISSI) and the Console Subsystem Interface (CSSI), are designed to enhance the operability and interoperability of new or existing land mobile radio systems.
ISSI technology allows for multiple radio core systems or RF subsystems to link together and form larger wide-area networks, supporting the “system-of-systems” concept. The CSSI interface provides interoperability among multiple dispatch console vendors and system infrastructure manufacturers, which enables third party P25 console options.
Given increased interest in both ISSI and CSSI technology, the Federal Partnership for Interoperable Communications, supported by the Department of Homeland Security Cybersecurity and Infrastructure Security Agency Emergency Communications Division, established the ISSI/CSSI User Working Group (comprised of users and manufacturers) and the Focus Group (users only) to explore the ISSI/CSSI technology environment including but not limited to, successfully connecting single and multiple manufacturer ISSI or CSSI systems, collecting user and manufacturer implementation procedures, troubleshooting methods, and identifying best practices.
This document’s purpose is to outline components for practitioners to consider when planning for and implementing an ISSI or CSSI implementation. The high-level components are rooted in best practices observed during all project phases by local, county, regional, and state agencies implementing ISSI/CSSI and are provided as a resource for others in the community who may be contemplating or implementing ISSI/CSSI. The six components are listed below; the first two are addressed in this volume while the other four will be addressed in a future volume.

Groton CT Police find Cost Savings through P25 Sharing
Details
Many Public Safety and government agencies are realizing significant Cost Savings through P25 Sharing. The Project 25 Technology Interest Group (PTIG) is pleased to share a recent example from the "The Submarine Capitol of the World", Groton Connecticut Police Department.
" Some of the advantages for the town include greatly enhancing police radio coverage and communications interoperability with neighboring departments to include Stonington, Groton Long Point, Environmental Conservation Police and the State Police. Communications interoperability is an important aspect of modern day policing and can greatly assist on a daily basis, during large scale events, joint operations and ultimately with officer safety. There are additional benefits to joining the state system to include the fact that the town will now maintain less infrastructure, utilize resources from the State of Connecticut and realize savings due to economies of scale by working with other communities and agencies who utilize this system."
"Comparable systems can cost in excess of 3.5 million dollars and the Town of Groton was able to join the state system at a fraction of the cost".
