The IntelliLink Gateway interoperability solution links multiple talk groups or channels between two or more different Land Mobile Radio systems including DMR, Project 25, LTR, SmartNet, EDACS, LTE, analog conventional and others.
Patches between the radio systems – whether wireline interfaces to DMR and P25 or with donor radios to legacy systems – are implemented between specific networks and do not rely on the Configuration and Monitoring tool to remain connected once the patch is established. Unlike other solutions, this methodology eliminates the “single point of failure.” Donor radios for the legacy system and the interfaces for the DMR or P25 systems can be tuned to establish interoperability with any talk group programmed into those particular donor radios or available in the DMR/P25 system. The IntelliLink(tm) Gateway does not require the use of a Catalyst Dispatch Console and may be used by agencies that either do not need a console or already have a console from a different manufacturer.
This solution is superior to other solutions because it manages the flow of audio between two radio systems to guard against lost audio. Catalyst provides an advanced interface to both the legacy radios and the wireline interfaces of DMR and P25. When talk groups on the two systems are patched together using the IntelliLink™ Gateway, Catalyst buffers the audio until the target radio system is ready to re-transmit it so that the complete transmission is routed between the legacy system and DMR. Rather than VOX, Catalyst uses the digital message from each system, when available, to know when each call starts and stops, creating a more reliable and faster interoperability solution. The IntelliLink™ Gateway also creates a visual record of every call to and from both systems so that the System Administrator can review the call flow after an incident.
A strong application for the IntelliLink Gateway involves older legacy radio systems striving to migrate to DMR. The IntelliLink Gateway provides a migration between these two radio networks, eliminating a “forklift” replacement of one radio system for the other. Instead, a graceful migration is accomplished on a timeframe that manages as user’s budget and operations capabilities. Advanced gateway connections between legacy mobile radios that have RF linkage are made between Legacy radio systems and a wireline Application Interface Specification (AIS) connection to the DMR Tier III system.
