Intellilink - Catalyst Communication Technologies

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.

Migration from legacy radio systems to next generation networks – whether P25, DMR, NXDN, LTE, FirstNet™ or others – is the primary application to take advantage of the benefits of the IntelliLink™ Gateway. IntelliLink™ Gateway creates interoperability between radios, channels and talk groups of legacy and new radio systems. As an EDACS™ user migrates to P25, for example, an IntelliLink™ Gateway connecting a Harris M7300 EDACS™ mobile radio with a P25 mobile radio can insure that radio communications between subscriber devices on these different systems is not lost during the transition. A similar application can be envisioned for legacy Motorola Smartnet™ users electing to migrate to a new DMR based system. Intelligent gateway connections between mobiles radios that have legacy RF linkage and gateways with a wireline DMR (using the Application Interface Specification or AIS) or wireline P25 or LTE (using the Console SubSystem Interface CSSI) connection comprise a powerful configuration.

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 can be 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. As IP Networks can be used to make the connection between IntelliLink™ Gateways, different architectures can be envisioned that solve specific migration problems.

Key Features

Key features include the complete flexibility to patch any two (or more) disparate radio systems, regardless of frequency band, manufacturer, or control protocol. Establish multiple simultaneous talk group patches to manage migration from legacy radio system to new standards based systems.

Connecting Networks

The IntelliLink™ Gateway can link two mobile radios together to patch radio communications between different networks. Through advanced control of certain radio systems, Catalyst technology dynamically manages the audio flow so that syllables are not lost. Trunked radio systems vary in the amount of time it takes to gain access to a channel. IntelliLink™ Gateways can store the audio until the trunked system is ready to receive it and then transmit the audio to the intended recipients.

Interoperability without Dispatch

Many interoperability solutions in the marketplace provide the ability to patch together one or more radios through a configuration setting established through a Dispatch Console. Catalyst technology manages interoperability at the Gateway, eliminating the need for a Dispatch console.

Wireline And Wireless

IntelliLink™ Gateway is infinitely flexible, and can patch a legacy analog radio through 2 or 4 wire audio and tone control to a P25 infrastructure using the CSSI Digital Ethernet interface. Many other configurations are possible. 

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.

Additional Features


A single IntelliLink™ Gateway can be configured to manage two, three or four multiband and/or multiprotocol radios that can be used to provide interoperability between Low Band, VHF, 700 MHz, and 800 MHz as well as Project 25, EDACS™, MDC-1200, DMR, NXDN, and conventional.

Simple and Intuitive Functionality

Catalyst can configure these units with a custom layout and stage it with your radios so that when you need communications, it will be ready. Just turn it on and immediately enhance your communications and record keeping.
