Catalyst Communications Technologies, Inc. demonstrated new capabilities for bridging traditional Land Mobile Radio systems and emerging Broadband systems. The company showed its Persistent Patch solution that enhances the robustness of connections between disparate communications systems. The company also showed how powerful wireline interfaces like the Project 25 Inter-RF Sub-System Interface (ISSI), Console Sub-System Interface (CSSI), and the Digital Fixed Station Interface (DFSI), as well as the Digital Mobile Radio Application Interface Specification (AIS), are linked to one another, to other traditional Land Mobile Radio (LMR) protocols, and to Broadband systems. The presentation emphasized Catalyst’s state-of-the-art platform that includes Windows 10-based user interfaces that can be easily adapted to work alongside emerging technologies ranging from on-scene video to the Internet of Things.
As Public Safety, Utilities, Federal, Education, and other agencies move toward leveraging broadband for push-to-talk voice communications, interoperability with LMR systems has grown as a priority. Catalyst displayed innovations that build on its well-established IP LinkTM technology to maintain connectivity between field personal using different types of devices. With Persistent Patch, these agencies can be confident that their audio will be routed to its destination despite dynamic environments. The demonstration showed Catalyst IP ConsoleTM and PropulsionTM consoles interfacing to P25, DMR, NXDN, MDC-1200, and EDACS-capable radios on the LMR side, and LTE on the broadband side.
Standards-compliant wireline interfaces provide powerful connectivity to traditional LMR systems, and the demonstration included products that support the P25 ISSI/CSSI and DFSI as well as the DMR AIS. These interfaces allow Catalyst interoperability and dispatch solutions to monitor large numbers of talk groups through a single interface in a spectrum-efficient manner. With newly available software from Catalyst, agencies are able to better prioritize the call flow through these interfaces to manage Critical Communications.
