Interoperability Overview
Interoperability has emerged as the greatest challenge in Land Mobile Radio (LMR) and Broadband Push-to-Talk (PTT) communications, and ESChat does Interoperability better than anyone. Our interoperability solutions address Inter-Agency Interoperability, Inter-System Interoperability, Inter-Product-Interoperability, Inter-Carrier Interoperability, and Inter-Vendor Interoperability.
Inter-Carrier Interoperability
You’d think that providing secure PTT communication across wireless carriers would be fundamental to all PTT services, but it’s not. ESChat provides cross-carrier interoperability without the need for gateways, special applications or incremental fees.
Inter-System Interoperability
Inter-System Interoperability is the ability to seamlessly communicate between ESChat and other communication platforms, including Land Mobile Radio (LMR) networks, Dispatch Console systems and Logging Recorder Systems. ESChat can interface with any LMR network, regardless of frequency band or protocol. ESChat provides both basic Gateway based interface solutions for Inter-System Interoperability, and also advanced Wireline interfaces solutions. Wireline solutions communicate without gateways, using standards-based protocols that include the P25 Inter Sub System Interface (ISSI) and OTAR/KMF Encryption Key Management Facility, as well as the DMR Application Interface Specification (AIS) for for DMR Radio and and Dispatch systems. Mission Critical call recording is available for SIPREC enabled logging recording solutions.
Inter-Product-Interoperability
ESChat’s Inter-Product Interoperability enables third parties to integrate ESChat technology into their own products and solutions with our Software Development Kits (SDK’s) and Application Programming Interfaces (API’s). ESChat technology is currently embedded into numerous Dispatch Console systems, LMR Gateway products, IoT Radios, and most recently, EF Johnson Technologies announced Viking Connect, Powered by ESChat.
Inter-Agency Interoperability
ESChat for Government is a hardened version of the ESChat broadband communication, collaboration, and interoperability platform. Our ‘Self Discovery’ feature provides public safety agencies a mechanism to ‘negotiate’ Inter-Agency Pathways which enable secure communication Talkgroups/Channels for Mutual Aid and Tactical Communications. In addition to PTT voice, the Inter-Agency pathways also support ESChat’s secure Multimedia Messaging and Location Sharing.
Inter-Vendor Broadband PTT Interoperability
Our commitment to interoperability extends beyond our platform. We’d prefer every customer selected ESChat as their broadband PTT solution of choice, but that’s not a realistic expectation. Therefore, we’re committed to ensuring there are methods to interoperate with competitive solutions in order to ensure our customers can communication with others who are using competitive products.
