Inter-RF Subsystem Interface (ISSI) and Console Subsystem Interface (CSSI) have shown immense potential as the preferred interfaces for interconnecting Project 25 (P25) LMR systems with long-term evolution (LTE) and other land mobile radio (LMR) networks. While these interfaces are standardized, the growing number of available offerings have introduced additional complexity and confusion for agencies looking to adopt ISSI/CSSI solutions. Our panel of experts will share what they've learned from their own implementations and help the audience understand what to expect when integrating new ISSI/CSSI-based capabilities into existing LMR networks and/or interconnecting LTE functionality.


During this presentation, attendees will gain from this presentation and how it will benefit the IWCE ecosystem:
1. How Standards-based ISSI and CSSI have immense potential as the primary interfaces for connecting multiple manufacturers' P25 LMR Systems, as well as integrating LTE systems
2. What early ISSI/CSSI adopters learned through implementation and suggested actions for future ISSI/CSSI functionality
3. Address the opportunities and challenges that exist when deploying ISSI/CSSI, including current efforts to improve the operability and interoperability of various P25 features
4. Address the future of ISSI/CSSI and alternative cloud-based solutions and the potential impacts on interoperability across both LTE and LMR systems when using non-standardized products
