LINc™ Multi-Level Secure Communications System

LINc Delivers Unmatched Security, Connectivity and Operator Flexibility for your Mission

LINc’s operator-focused design combines audio communications across multiple levels of classification in a standard headset using a single, intuitive control interface. LINc distributes industry standard network audio (ex: VoIP, SIP and RTP) at all classifications, analog red/black radios and other audio sources to mission operators.

LINc provides the most demanding aircrews with the most secure and capable communications package. LINc’s flexible control and architecture enables tight integration with aircraft mission systems, ensuring operator efficiency and capability across mission sets. Operators can access multi-level mission audio through LINc, as well as interface with existing equipment to minimize platform modification.

Quick-View Status and Alerts/Warnings

System-Wide Activity Indicators

Emergency call bus switch to allow hardwired communications in the event of system failure

Local Conference for Trainer/Trainee Operations, or Shared Equipment

Page Navigation

Focus: deafen audio from all sources except the current selection, to prioritize the current audio; quickly adjust the global audio settings of all non-selected conferences to a configurable value, allowing the operator to focus their attention on their currently selected asset temporarily

Local position brightness adjustment

Menu setting and configuration

Channel Volume: adjust the volume of the currently selected audio source

Azimuth: Configure the perceived physical direction of the currently selected audio source. This can be to the left, right, in front, or somewhere in-between. This is useful for segregating similar audio sources to increase operator awareness during high-communications bursts.

Deselect (DESEL): transition the currently selected audio source to the inactive state (no longer heard)

Default (DFLT:) return local position to the power-up default settings and selections; reset all audio conferences to the initial configuration present at system power-up, resetting all individual volume adjustments as well

Local positions master volume control

Reduce Risk - Expedite Integration

LINc provides unified voice interoperability across joint and multi-domain operations. It connects similar and dissimilar manned and unmanned assets using connected line-of-sight (LOS) and beyond-line-of-sight (BLOS) links, while interfacing with command-and-control centers, ships and ground-based operators. LINc serves as the nervous system for sending and receiving cross-domain audio communications on the modern battlefield, connecting all endpoints together in a secure, reliable manner.

LINc interconnects ships, aircraft, ground vehicles, command-and-control facilities and individual personnel (including software-only ATAK-style operations). LINc interfaces with existing LOS/BLOS military radios (UHF, VHF, HF, etc.), mission-system audio, Voice over IP (VoIP) and networked audio, voice-capable military data links (for example, Link-16 J-Voice), and air-traffic communication radios.
