The Digital Communications Network (DCN) provides the communication infrastructure for ground combat training systems. It the radio-frequency link between the Exercise Control (EXCON) center and the soldier/vehicle instrumentation, allowing real-time monitoring of the players and mission control.

Components include the main DCN computer, antenna masts, relay radios, player units, and EXCON/AAR products such as PC-RIS, and antennas. Antenna mast variations range from fixed 100 meter towers to small transportable units.

Cubic has various digital communications designs with a range of robust data protocols and operational frequencies in the VHF, UHF and cellular bands. In all cases, Cubic's DCN equipment is:

• Highly dependable, both physically and in data throughput
• Graceful coexistence with other battlefield communications systems
• Transparency to the warfighter in size, weight and power demands

Cubic DCNs currently in use include:

• CMTC: 12 networks, approximately 1,000 instrumented players, 3 second reporting rate,
• JRTC: Three networks, approximately 2,000 instrumented players, variable reporting rates,
• AWES: Four networks, approximately 1,500 instrumented players, variable reporting rates
