iDirect DLC-T Line Card


The DLC-T is a next generation defense transmit line card compatible with both the Evolution® and Velocity™ platforms. The DLC-T features TRANSEC, FIPS 140-2 Level 3, DVB-S2, linear pre-distortion, higher MODCODs, and is DVB-S2X ready. Designed for high throughput satellites (HTS) networks.


The Defense Transmit Line Card (DLC-T) is suited for supporting secure voice, data, and video communication links for mission-critical military and COTM broadband applications. It provides 125 MHz analog passband capability across the TxIF L -band spectrum and features DVB-S2 Adaptive Coding and Modulation (ACM) on the outbound channel. The DLC-T provides FIPS 140-2 Level 3 security with the introduction of an on-board TRANSEC module. The DLC-T is compatible with series 15100 and 12200 hub chassis models and synchronized in timing/frequency to PPS/10 Mhz references distributed across the backplane. The specifications below represent the full capability of the DLC-T. Actual performance is based upon the software release deployed.
