  • Page 26: About This Manual

    This manual provides installation and operation information for the Comtech EF Data CDM-570 and CDM-570L satellite modems with optional IP Module. These two modems are essentially identical in their operation. The CDM-570 operates in the 70/140MHz IF band, whereas the CDM-570L operates at L-band, and includes support for externally connected BUCs and LNBs.

  • Page 27: Electrical Safety

    The user should observe the following instructions: IMPORTANT Fuses The CDM-570/570L is fitted with two fuses - one each for line and neutral connections. These are contained within the body of the IEC power inlet connector, behind a small plastic flap.

  • Page 28: Telecommunications Terminal Equipment Directive

    The CDM-570/570L is shipped with a line inlet cable suitable for use in the country of operation. If it is necessary to replace this cable, ensure the replacement has an equivalent specification.

  • Page 31: Chapter 1. Introduction

    Introduction The CDM-570L is an L-band Satellite Modem, intended for closed network applications. The CDM-570 Satellite Modem is the 70/140 MHz IF version of the same modem. Apart from the IF frequency band, the two modems are essentially identical. •...

    1.1.2 AUPC An important feature in the CDM-570/570L is the addition of Automatic Uplink Power Control (AUPC). This feature enables the modem to automatically adjust its output power to maintain the Eb/No of the remote end of the satellite link constant. This provides protection against rain fading, a particularly severe problem with Ku-band links.

  • Page 33: Verification

    RF switch connects the modulator output to the demodulator input. When normal operation is again selected, all of the previous values are restored. 1.1.5 Data Interfaces The CDM-570/570L includes, as standard, a universal data interface that eliminates the need to exchange interface cards for different applications. The interfaces offered include: •...

  • Page 34: Fast Accessible Options

    1.3.2 FAST System Theory FAST is an enhancement feature available in Comtech EF Data products, enabling on- location upgrade of the operating feature set without removing a modem from the setup. When service requirements change, the operator can upgrade the topology of the modem to meet those requirements within minutes after confirmation by Comtech EF Data.

  • Page 35: Implementation

    Introduction MN/CDM570L.IOM purchased at any time from Comtech EF Data. Once obtained, the access code is loaded into the unit through the front panel keyboard or the rear remote port. With FAST technology, operators have maximum flexibility for enabling functions as they are required.

  • Page 36: New In This Release

    8-QAM - a new modulation type first introduced in the CDM-600 in November 2004, for use with Comtech’s new LDPC codec, has been added. Here, in the CDM-570/570L it has been paired with Turbo Product Coding. See Chapter 7, Section 7.5.3 for a description of its advantages. For those users who have already purchased the 8-PSK FAST option, this is a totally free upgrade.

    Chapter 2. INSTALLATION Unpacking Inspect shipping containers for damage. If shipping containers are damaged, keep them until the contents of the shipment have been carefully inspected and checked for normal operation. The modem and manual are packaged in pre-formed, reusable, cardboard cartons containing foam spacing for maximum shipping protection.

  • Page 38: Mounting

    MN/CDM570L.IOM Mounting If the CDM-570/570L is to be mounted in a rack, ensure that there is adequate clearance for ventilation, particularly at the sides. In rack systems where there is high heat dissipation, forced air cooling must be provided by top or bottom mounted fans or blowers.

All configurations are carried out entirely in software. The unit should first be configured locally, using the front panel keypad and display.

  • Page 41: Chapter 3. Functional Description

    465MHz, and from there further translated to baseband, using the carrier recovery VCO. In the CDM-570, the conversion of signals in the range 50 to 180 MHz is directly to baseband. This is a complex mix, resulting in the signal once more being split into an in-phase (I) and a quadrature (Q) component.
  • Page 42 From here, the receive clock and data signals are routed to the terrestrial interface, and are passed to the externally connected DTE equipment. The CDM-570/570L signal processing functions are performed in a single, large Field- Programmable Gate Array (FPGA) , which permits rapid implementation of changes, additions and enhancements in the field.

    At the time of writing, Comtech EF Data is planning to release a new codec, which is a combination of Turbo Product Coding and Low Density Parity Check (LDPC) coding.

  • Page 120: Viterbi

    (i.e., does not fail rapidly below a certain value of Eb/No). Note that in BPSK mode, the CDM-570/570L 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 121: Table 7-2. Concatenated Rs Coding Summary

    Viterbi decoder is spread out over a number of interleaving frames, so errors entering the RS decoder do not exceed its capacity to correct those errors. In the case of the CDM-570/570L , two different RS code rates are used, according to the mode of operation.

  • Page 122: Trellis Coding (Requires 8-Psk/8-Qam Fast Option)

    – the natural consequences of the higher-order modulation. The CDM-570/570L 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 123: Turbo Product Codec (Hardware Option)

    2 – 3 dB below the Viterbi/R-S or TCM cases With this release of the CDM-570/570L , Comtech EF Data now provides the best Forward Error Correction technology currently available, offering a very broad range of TPC code rates, combined with the entire range of modulation types, from BPSK to 16-QAM.

  • Page 124: 8-Qam Moddulation

    In many cases, FEC methods that provide increased coding gain do so at the expense of increased processing delay. However, with TPC, this increase in delay is very modest. The table below shows, for the CDM-570/570L , the processing delays for the major FEC types, including the three TPC modes: Table 7-5.

    There are occasions when a user may wish to operate a satellite link with no forward error correction of any kind. For this reason, the CDM-570/570L 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.

  • Page 127: Rates Above 2.5 Msymbols/Sec

    However, if uncoded operation is used, there is no way to recognize a data false lock. The demodulator will indicate that it is correctly locked, but the data out will not be correct. This problem has been almost entirely eliminated in the CDM-570/570L with the fast acquisition algorithm which includes Fast Fourier Transform (FFT) techniques. However,...
