IntelliLink™ Gateway

The IntelliLink™ Gateway links multiple talk groups or channels across frequency bands and over the air protocols including DMR, Project 25, LTR, SmartNet, EDACS, analog conventional, and others. Special packages are available supporting two, three or four donor radios and custom configurations are available with no limits on audio paths and supporting both wireline and wireless interfaces.

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 legacy control stations (SmartNet, EDACS, LTR, etc.), modern control stations (DMR, P25, NXDN), and to the wireline interfaces for DMR, P25, and LTE. 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 the new one. Rather than VOX or COR, Catalyst uses the digital messaging, when available, from each system to know when each call starts and stops, creating a more reliable interoperability solution. The IntelliLink™ Gateway also creates an electronic record of every call to and from both systems so that the System Administrator can review the call flow after an incident.

Up to four mobile radios are controlled by each server PC. There is no limit on the number of talk groups or patches supported. The donor radios and their server PC may be located in different geographic regions, connected by an Internet Protocol network. If one PC is taken off-line, the others can continue to route audio. One of the PCs will also include configuration and monitoring tools; a single monitor, keyboard, and mouse are user provided to manage the applications on all PCs. Once the patch is set, the server PCs can operate independent of the configuration tool.

Patches between radio systems – whether through wireline interfaces (DMR, P25, LTE, conventional) or utilizing donor radios – are implemented directly between specific networks and do not rely on a console type device to remain connected once the patch is established. Unlike other solutions, this methodology eliminates the “single point of failure.” Donor radios for both legacy and modern systems as well as infrastructure interfaces to DMR, P25, LTE and conventional systems can be configured to establish interoperability between any specific talk groups programmed into those particular donor radios or available via the wireline interface.

A strong application for the IntelliLink™ Gateway involves a smooth migration from older legacy radio systems to DMR, P25, or LTE systems. Intelligent gateway connections between mobiles radios that have legacy RF linkage and gateways with a wireline DMR (using the Application Interface Specification AIS) or wireline P25 or LTE (using the Console SubSystem Interface CSSI) connection comprise a powerful configuration. A graceful migration is accomplished on a timeframe that can be managed to best meet an agency’s budget and operational requirements.

The IntelliLink™ 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.

Notice anything different? We'll be updating everyone this month with news about what is going down at IWCE in Orlando March 5-8. We're excited to tell you we'll have a major new product announcement. Here's a spoiler alert! Can you guess???
