DMD20 Universal Satellite Modem
The DMD20 Satellite Modem breaks new ground in flexibility, operation and cost. With standards including
IDR, IBS and DVB, and covering data rates up to 20 Mbps, this 1RU duplex modem covers virtually all your
Satellite IP, Telecom, Video and Internet applications. Switch between spur-free 70/140 MHz operation
and L-Band without any configuration changes. It's all in the same box!
DMD20 now offers DoubleTalk Carrier-in-Carrier bandwidth compression. DoubleTalk Carrier-in-Carrier,
based on patented “Adaptive Cancellation” technology, allows transmit and receive carriers of a duplex link
to share the same transponder space. DoubleTalk Carrier-in-Carrier is complementary to all advances in
modem technology, including advanced FEC and modulation techniques. As these technologies approach
theoretical limits of power and bandwidth efficiency, DoubleTalk Carrier-in-Carrier utilizing advanced signal
processing techniques provides a new dimension in bandwidth and power efficiency.
The extensive list of software options allows for budgeting the modem for today's needs while covering
tomorrow's plans. These options can be purchased and then activated in seconds via the front panel.
Additional hardware options like Turbo Product Code (TPC), Low Density Parity Check Code (LDPC),
interface expansion, high-stability and DC operation complete the modem's dynamic feature coverage.
Stock this modem at its minimum configuration (and cost) locally for immediate distribution. Then configure
on-site, allowing huge savings in time and dollars with just-in-time feature installation.
The DMD20's impressive remote accessibility surpasses all others in the field. Remote control via the RLLP
(Radyne Link Level Protocol), Ethernet 10Base-T (SNMP and Web browser) includes control of all the
modem's features plus software maintenance. Additionally, the two-line backlit LCD can be supplemented
with terminal software running on a PC or laptop. The modem now presents its entire monitor and control
functions on the big screen.
Supported by an extensive line of redundancy switches, converters, encoders and decoders, the DMD20
can be built into any satellite requirement. The DMD20 is compatible with DMD15, DMD50, CM701,
MD2401 and CDM-600.
