Why the Comtech DMD20 LBST Stands Out

The DMD20 LBST modem is not just another piece of hardware; it is a complete communication enabler. With support for data rates up to 20 Mbps, it covers virtually all applications in IP, telecom, video broadcasting, and Internet services. Its modular design, field-upgradeable software, and broad compatibility make it ideal for industries that require scalable, dependable, and cost-effective satellite links.

Key Highlights

• DoubleTalk® Carrier-in-Carrier® Technology – Patented adaptive cancellation allows transmit and receive carriers to overlap in the same transponder, dramatically improving bandwidth and power efficiency.
• Wide Modulation Support – BPSK, QPSK, OQPSK, 8PSK, 8-QAM, and 16-QAM provide flexibility for different link budgets.
• Flexible Data Rates – From 2.4 kbps up to 20 Mbps, supporting everything from narrowband to broadband applications.
• Advanced FEC Options – Viterbi, Reed-Solomon, Trellis, Sequential, Turbo Product Code (TPC), and LDPC provide unmatched error correction capabilities.
• Comprehensive Interfaces – Ethernet, HSSI, DVB-ASI/SPI, G.703, RS-422/530, and V.35 ensure compatibility with legacy and modern systems.
• Smart BUC Support – Integrated FSK communications channel for monitoring and controlling smart BUCs.
• Remote Management – Web-based GUI, SNMP, and Comtech’s RLLP protocol for full monitoring and control.
• Compact Design – 1RU rack-mount unit (8.5 lbs), suitable for mobile, government, and enterprise deployments.
