The interface transmits data in asynchronous serial form, using ASCII characters.

All of the Targets receive the packet, but only one (the intended) will reply. The Target enables its output line driver and transmits its return data packet back to the Controller in the other direction, on the physically separate pair.

    CDM-570A/570AL Satellite Modem with Optional Packet Processor MN-CDM570A Serial-based Remote Product Management Revision 3 All messages from Controller-to-Target require a response, with one exception: This will be either to return data that has been requested by the Controller, or to acknowledge reception of an instruction to change the configuration of the Target. The exception to this is when the Controller broadcasts a message (such as Set Time/Date) using Address 0, when the Target is set to EIA-485 mode.

    You can fully monitor and control ODU operations as follows: • By using the CDM-570A/570AL front panel keypad and VFD. The Front Panel ODU menu branch allows you to configure power supplies, a 10 MHz reference, and low/high current alarm thresholds for the CDM/R-570AL BUC and LNB M&C. LO (Local Oscillator) menus allow you to set up the upconversion and downconversion settings for the BUC and LNB so that you can view the satellite frequencies as well as the modem IF input/output frequencies.

  • Page 433: Appendix B. Fec (Forward Error Correction) Options

    Appendix B. FEC (FORWARD ERROR CORRECTION) OPTIONS Overview The CDM-570A/570AL Satellite Modem is equipped with VersaFEC (short-block LDPC), Turbo Product Code (TPC), Viterbi, Reed-Solomon (Closed Network), and Trellis with concatenated Reed-Solomon Forward Error Correction encoders/decoders. The constraint lengths and encoding polynomials are Closed Network compatible with the vast majority of existing modems from other manufacturers.

  • Page 434: Viterbi

    (i.e., does not fail rapidly below a certain value of Eb/No). Note that, in BPSK mode, the CDM-570A/570AL only permits a coding rate of 1/2. Because the method of convolutional coding used with Viterbi, the encoder does not preserve the original data intact, and is called non-systematic.

  • Page 435: Reed-Solomon Outer Codec

    CDM-570A/570AL Satellite Modem with Optional Packet Processor MN-CDM570A Appendix B Revision 3 Reed-Solomon Outer Codec The concatenation of an outer Reed-Solomon (RS) Codec with Viterbi decoder first became popular when it was introduced by Intelsat in the early 1990s. It permits significant improvements in error performance without significant bandwidth expansion.

  • Page 436: Trellis Coding Modulation (Tcm) (Fast Option

    – the natural consequences of the higher-order modulation. The CDM-570A/570AL implements a Closed Network version of Rate 2/3 8-PSK/TCM/RS, using either the 220, 200 or 200,180 Reed-Solomon outer codes. Although not compatible, it provides identical performance to the Open Network IESS-310 standard.

  • Page 437: Turbo Product Codec (Fast Option

    Turbo Codes have been developed, Turbo Convolutional Codes (TCC), and Turbo Product Codes (TPC, a block coding technique). Comtech EF Data has chosen to implement an FEC codec based on TPC. A Turbo Product Code is a 2 or 3 dimensional array of block codes. Encoding is relatively straightforward, but decoding is a very complex process requiring multiple iterations of processing for maximum performance to be achieved.

It remained clear, however, that the Shannon Limit was still an elusive target. Berrou’s work on Turbo Codes showed, through the use of an ingeniously simple approach (multiple, or iterative decoding passes) that it is possible to achieve performance close to the Shannon Limit.

    There are occasions where a user may wish to operate a satellite link with no forward error correction of any kind. For this reason, the CDM-570A/570AL offers this uncoded mode for three modulation types – BPSK, QPSK, and OQPSK. However, the user should be aware of some of the implications of using this approach.

In order to accomplish the task of carrier recovery, the demodulator must use a non-linear process. A second-order non-linearity is used for BPSK, and a fourth-order non-linearity is used for QPSK.

Normal band-limited QPSK produces an RF signal envelope that necessarily goes through a point of zero amplitude when the modulator transitions through non-adjacent phase states.

    The transponder downlinks the composite signal containing both carriers on the same band to the CDM-570A/AL which then translates the signal to near baseband where it can be filtered (decimated) and then processed as a complex envelope signal. The CDM-570A/AL then suppresses the version of the near end carrier on the downlink side and then passes the desired carrier to the demodulator for normal processing.

ANSWER: • The QoS system first drains Priority 1 traffic. Since the management data stream is only 200 Kbps, after serving Priority 1 traffic, QoS still has 9.8 Mbps (10.0-0.2=9.8).

However, while the QoS system recognizes data rate, both Layer 2 QoS and Layer 3 QoS operate on data rate. Therefore, while the symbol rate will be constant in ACM mode, the data rate will not be constant.
