Comtech Radyne DMD2050 Universal Satellite Modem

The Comtech Radyne DMD2050 Military Standard Universal Satellite Modem is designed to comply with the widest possible range of
U.S. Government and commercial standards and is compatible with a largest number of satellite modems in the industry.

This item is now configurable for easy on-line purchase!

The DMD2050 provides highly advanced and bandwidth-efficient forward error correction (FEC). Advanced FEC options include Turbo Product Codes (TPCs) and Low Density Parity Check (LDPC). Legacy support for Viterbi, Trellis, Concatenated Viterbi Reed-Solomon, and Sequential FEC are also included. A complete range of modulation types is supported including BPSK, QPSK, OQPSK, 8-PSK, 8-QAM, and
16-QAM.

Advanced FEC and modulation capabilities are integrated with the revolutionary DoubleTalk® Carrier-in-Carrier® bandwidth compression allowing for maximum state-of-the-art performance under all conditions. This combination of advanced technologies enables multi-dimensional optimization, allowing satellite communications users to:

  • Minimize required satellite bandwidth
  • Maximize throughput without using additional
    transponder resources
  • Maximize availability (margin) without using
    additional transponder resources
  • Enable use of a smaller BUC/HPA and/or
    antenna
  • Or, a combination of the above to meet
    specific mission needs

Data rates range from 2.4 kbps to 52 Mbps and symbol rates from 4.8 ksps to 30 Msps.

The modem provides a standard MIL-STD-188-114 (EIA-530 / RS-422), serial interface. It can optionally be configured with EIA-613 (HSSI), G.703 (T1/E1/T2/E2 & T3/E3), DVB ASI/SPI and 10/100/1000 BaseT Ethernet Interfaces. Drop & Insert functionality is supported on the G.703 interface.

A dual IF interface supports low IF (52-88, 104-176 MHz), and L-band (950-2000 MHz) frequency ranges.

Cost-effective, ultra-high reliable systems are enabled in conjunction with the RCS-11 1:1 redundancy switch, and/or the RCS-20 M:N redundancy switch.

Adtec Encoders Send Four Concurrent GIGE Routes per Destination

Adtec’s HD422 Encoders can send Four CONCURRENT (same time) GIGE routes (IP destinations) of the transport stream with unique configuration and FEC (SMPTE 2022) setting per destination! These routes are concurrent with ASI operational and internal constant capture with the hard drive if the TS rate is lower than 40 Mbs (old PATA hard drive limitation).

Adtec HD422 can encode four (4) MPEG 1 Layer 2 {they even support phase alignment of the MPEG 1 Layer 2 audio allowing surround sound without external processors when using the Tandberg TT1290 IRD}. Encoding also supports two (2) Dolby AC3 and two (2) MPEG 1 Layer 2 or any combination up to two each. Example, Encode one (1) Dolby AC3 and encode three (3) MPEG 1 Layer 2 audios.

Adtec can passthrough Dolby AC3/5.1/E, LPCM and Linear Acoustic E2. Passthrough support is via SDI and or AES. We can passthrough up to two (2) compressed Dolby (AC3/5.1/E) or Linear Acoustic E2 or two (2) SMPTE 302M (LPCM) audio streams. Dolby E, E2 and LPCM each take 2.308 Mbs.

Throughput for the 2.308 data rate:
Dolby E supports 4×2 or 5.1+2 (8 channels)
LPCM supports stereo audio (2 channels)
Linear Acoustic Stream Stacker E2 supports two (2) sets 4×2 or 5.1+2 or a total of sixteen (16) channels. E2 is equivalent to two (2) Dolby E boxes.
Base model NTT 9100 can pass one SMPTE 302M (nomenclature they use for Dolby E) and encode 2 MPEG 1 Layer 2. By adding NTTs additional audio board, they can pass two (2) SMPTE302M and even claim to pass four (4) with a very unique method with no audio encode capabilities with either two (2) or four (4) Dolby E passthrough. NTT is limited to TWO PIDs total when in passthrough mode. They claim they can passthrough four (4) Dolby E by combining two Dolby E payloads per AES3. This requires external audio processing to mix two Dolby E payloads onto a 96 Khz AES3 interface and requires sharing a single PID for two (2) Dolby E payloads. NTTs four (4) Dolby E passthrough lacks interoperability and Adtec deems it as very fragile because there is no control or monitoring at the transport layer nor lip sync adjustment per Dolby E stream; they are grouped in pairs of Dolby E. Simply put, they adjust the PID therefor both audios get the same adjustment. I would argue that Adtec and NTT can both passthrough two (2) Dolby E payloads. The Adtec advantage is the ability to pass two (2) and still encode two (2) MPEG 1 Layer 2 audios.
