iDirect DLC-R Line Card


The DLC-R is a next generation defense receive line card compatible with both the Evolution® and Velocity™ platforms. The DLC-R features TRANSEC, FIPS 140-2 Level 3, Adaptive TDMA, multi-channel support and a path to higher symbol rates. Designed for high throughput satellites (HTS) networks.


The Defense Receive Line Card (DLC-R) is suited for supporting secure voice, data, and video communication links for missioncritical military applications in conjunction with a modulator card (such as DLC-T). The DLC-R provides FIPS 140-2 Level 3 security with the introduction of an on-board TRANSEC module. The line card features a multi-channel demodulator with up to 16 channels operating in either multi-frequency Adaptive TDMA or Adaptive SCPC Return mode and with aggregate return channels of up to 29 Msps. The specifications below represent the full capability of the DLC-R. Actual performance is based upon the software release deployed.
