Catalyst Announces System Release 6.2

August 17, 2015 – 81st Annual APCO Exposition, Washington, DC:  Catalyst Communications Technologies, Inc., a leading provider of IP-based solutions for Critical Communications, announced System Release 6.2 for its dispatch and interoperability solutions. This latest version of Catalyst software includes an enhanced Project 25 Console Subsystem Interface (CSSI) that routes Unit IDs from other radio systems to P25 subscriber units and supports distributed CSSI gateway hardware for redundancy and agency autonomy. This innovative embodiment of the P25 standards enables intelligent interoperability across the most widely used proprietary and standards-based radio systems in the United States. Release 6.2 also provides additional flexibility for dispatcher controls and other enhancements to the Catalyst product suite.

The P25 CSSI is the wireline interface described in the TIA standards and provides direct control of P25 trunked radio systems. With it, dispatchers are able to pre-empt subscriber units, monitor large numbers of talk groups, and maximize spectrum utilization. Previously Catalyst demonstrated the CSSI interface for its dispatch and interoperability solutions, including patching the audio with other radio systems. Now Catalyst customers can also pass the Unit ID of a subscriber radio using a different system to a P25 subscriber radio. Neighbors with legacy systems like SmartNet™, EDACS™, and MDC 1200 as well as those with more recent systems like Digital Mobile Radio, cellular PTT, and even other, independent P25 systems or P25 talk around users, can be identified by ID or alias on the display of a P25 portable or mobile radio. The CSSI interface is available for dispatch solutions using the Catalyst IP|Console™ and Interoperability-only solutions using IntelliLink™. Existing Catalyst systems can be upgraded to include CSSI functionality.

Public Safety, Federal, and other P25 users value robust solutions that can be controlled by their agency. Release 6.2 further addresses these requirements with the enhanced CSSI interface. Now each agency can connect to a P25 network with its own CSSI hardware, configured to optimize its unique requirements. For instance, certain talk groups may be given priority to insure that those First Responders are heard by dispatchers or other field personnel; call recorders can be controlled as needed, and the CSSI gateway hardware can be independently located to further enhance the robustness of the solution.

Catalyst president, Robin Grier, praised his team, saying, “The innovators at Catalyst have done it again!  I’m so proud of the leadership our products group continues to demonstrate, bringing valuable new capabilities to First Responders, Federal agents, and others using Project 25.”

Catalyst is currently shipping systems with Release 6.2.
