IntelliLink™ Gateway from Catalyst Connects Disparate Networks

Intelligent Interfaces to Radio Networks Redefines Interoperable Radio Communications

IWCE 2017, Las Vegas, NV – March 28, 2017

Catalyst Communications Technologies, Inc., a leading provider of IP-based Dispatch and Interoperability solutions for Critical Communications, today announced the IntelliLink™ Gateway. This flexible Interoperability solution links multiple talk groups or channels between different Land Mobile Radio systems including Digital Mobile Radio (DMR), Project 25 (P25), LTR, SmartNet, EDACS, and analog conventional to one another as well as to LTE-based systems.

Patches between the radio systems – whether through wireline interfaces to DMR and P25 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 such “single points of failure.” Donor radios for both legacy and modern systems as well as infrastructure interfaces to DMR and P25 systems can be configured to establish interoperability between any specific talk groups programmed into those particular donor radios or available in the DMR/P25 system. The IntelliLinkTM 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 also superior to competing 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.

A strong application for the IntelliLink™ Gateway involves migration from older legacy radio systems to DMR, P25, or LTE systems. Catalyst president Robin Grier points out “the IntelliLink™ Gateway facilitates a gradual migration process between the two radio networks, eliminating a ‘forklift’ replacement of one radio system for the other. This graceful migration is accomplished on a timeframe that can be managed to best meet the agency’s budget and operational requirements.” Intelligent gateway connections between mobile radios that have legacy RF linkage and gateways with a wireline DMR (using the Application Interface Specification or AIS) or wireline P25 (using the Console SubSystem Interface or CSSI) connection comprise a powerful configuration.
IntelliLink™ Gateway demonstrations at the International Wireless Communications Exposition (IWCE) will take place in Catalyst Booth #1445 throughout the day on March 29 & 30 at the Las Vegas Convention Center. Catalyst personnel will exhibit Innovation Everywhere including Dispatch Console solutions, Radio Interface technology, DMR capabilities, and new Hardware and Packaging innovations. They will also be on hand to discuss critical communications solutions specific to visitor’s applications.
