A 4-port Gigabit Ethernet switch, advanced routing and Quality of Service protocols are supported as part of the feature-rich IP functionality.
Traffic shaping allocates bandwidth in a controlled manner between competing data streams. This allows data services — including the satellite portion of the link — to be fully provisioned end-to-end rather than being simply ‘best effort’.
Large bandwidth reductions are achieved using a range of data compression and acceleration techniques. Paired Carrier (incorporating ViaSat’s patented PCMA technology) can further halve satellite bandwidth requirements.
State-of-the-art forward-error-correction (FEC) technology includes Turbo and LDPC. Lowlatency FastLink LDPC is attractive for lowdata- rate links. Single/multistream DVB-S2 is also supported.
Embedded satellite and IP diagnostic tools are included and are the most sophisticated available on the market.
The PD155i is fully compatible with all other Quantum-series modems in IP closed modes.

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.
