Chapter 1. INTRODUCTION 1.1 Overview The CDM-710 Broadcast Satellite Modem (Figure 1-1) is a high symbol/bit-rate unit, intended for operation in broadcast and enterprise applications. It operates over satellite links at symbol/data rates up to 45 Msps. Various modulations and coding combinations compliant with DVB-S, DVB-DSNG and DVB-S2 are provided.
CDM-710 Broadcast Satellite Modem Introduction Revision 10 MN/CDM710.IOM The modem is compact, being 1RU high x 18.65 inches deep with low power consumption. It has a front panel VFD display and keypad for local configuration and control, although it can be fully remote-controlled via a RS-485 bus or 10/100 Base-T Ethernet Interface. A block diagram of the modulator is shown in Figure 1-2.

CDM-710 Broadcast Satellite Modem Introduction Revision 10 MN/CDM710.IOM 1.2.2 Verification The unit includes a number of tests for rapid verification of the correct functioning of the unit. Selection of a CW carrier permits measurement of carrier center frequency or phase noise characteristic. A single-sideband carrier also is available at the operating symbol rate to check I and Q phase and amplitude balance. When normal operation is again selected, all of the previous values are restored. 1.2.

Chapter 3. FUNCTIONAL AND PHYSICAL DESCRIPTIONS 3.1 Overview The modem is constructed as a 1RU high rack-mounting chassis, which can be freestanding, if desired. Rack handles at the front facilitate removal from and placement into a rack. The satellite modem performs several key functions: • • • • • • • It accepts incoming data from the terrestrial interface and converts it into appropriate clock and data signals. The modulator operates on the data to frame and encode it for transmission.
CDM-710 Broadcast Satellite Modem Functional and Physical Description Revision 10 MN/CDM710.IOM An Rx carrier from the satellite is received by the demodulator and reverses the process performed by the modulator. The demodulator has an FEC decoder that corrects errors incurred during transmission to improve the integrity of the data delivered to the data interface. A synthesizer in the demodulator is programmed to select the desired carrier from the transponder.

Chapter 6. FLASH UPGRADING 6.1 Overview The CDM-710 eliminates the need for updating firmware by physically replacing EPROMs. Instead, the CDM-710 modem uses ‘flash memory’ technology internally. This makes software upgrading very simple, and updates can now be sent via the Internet, E-mail, or on disk. The upgrade can be performed without opening the unit, by simply connecting the modem to the Ethernet port of a computer.
CDM-710 Broadcast Satellite Modem Flash Upgrading 6.2 Revision 10 MN/CDM710.IOM Ethernet FTP upload procedure: 1. Identify the reflashable product, firmware number, and version for download. The current base modem M&C version can be viewed at the top-level menu of the front panel display (press “CLR” button several times to view).
CDM-710 Broadcast Satellite Modem Flash Upgrading Revision 10 MN/CDM710.IOM The downloadable files are stored in two formats: *.exe (self extracting) and *.zip (compressed). Some firewalls will not allow the downloading of *.exe files. In this case, download the *.zip file instead. For additional help with "zipped" file types, refer to "pkzip for windows", "winzip", or "zip central" help files. Pkzip for DOS is not supported due to file naming conventions. 4.
CDM-710 Broadcast Satellite Modem Flash Upgrading Revision 10 MN/CDM710.IOM 8. Verify the file transfer. a. The PC should report that the file transfer has occurred, and the display on the modem will start reporting “PROGRAMMING FLASH SECTOR#xx – PLEASE WAIT”. IMPORTANT Stopping the FTP before the “PROGRAMMING FLASH SECTOR#xxPLEASE WAIT” screen has finished could lead to an incomplete download and a repeat of step 8a. b. Terminate the FTP session by typing "bye" and closing the DOS window. c.
Chapter 7. FORWARD ERROR CORRECTION OPTIONS 7.1 Introduction The CDM-710 Modem operates with error correction base upon the DVB standards: • DVB-S: QPSK with concatenated Viterbi and Reed Solomon. • DVB-DSNG: 8-PSK and 16-QAM with concatenated Viterbi and Reed Solomon. • DVB-S2: QPSK, 8-PSK, 16-APSK and 32-APSK with concatenated Low Density Parity Code (LDPC) and Bose-Chaudhuri-Hocquenghem (BCH).
CDM-710 Broadcast Satellite Modem Forward Error Correction Options Revision 10 MN/CDM710.IOM LDPC also functions differently than Viterbi decoding by using iterative decoding. In this process the data initially corrected by the LDPC decoder is re-encoded and run through the decoder again to correct additional errors. Key to this is the soft decision output from the LDPC decoder and a high-speed processor operating at a rate much higher than the data rate.
CDM-710 Broadcast Satellite Modem Forward Error Correction Options Revision 10 MN/CDM710.IOM The relation between the two quantities is given by: Eb/No = Es/No - 10xLog(Spectral Efficiency) The table that follows provides the spectral efficiency for all of the DVB schemes. Another useful parameter is the occupied bandwidth is the bandwidth between -10 dB points of the power spectral density, which are approximately: Occupied Bandwidth = 1.19 x Symbol Rate, for 35% Rolloff = 1.

Chapter 12. CDI-60 HSSI Interface 12.1 Introduction This data interface is a plug-in module that inserts into the rear of the modem chassis. It provides physical and electrical connection between the external terrestrial device and the internal circuitry of the modulator or demodulator. By convention, a modem is Data Communications Equipment (DCE) where Tx data enters the data interface and Rx data exits it. The plug-in interface has full duplex capability.

Appendix A. REMOTE CONTROL A.1 Introduction This appendix describes the protocol and message command set for remote monitor and control of the CDM-710 Broadcast Satellite Modem. The electrical interface is either an RS-485 multi-drop bus (for the control of many devices) or an RS-232 connection (for the control of a single device), and data is transmitted in asynchronous serial form, using ASCII characters.
CDM-710 Broadcast Satellite Modem Remote Control A.3 Revision 10 MN/CDM710.IOM RS-232 This a much simpler configuration in which the controller device is connected directly to the target via a two-wire-plus-ground connection. Controller-to-target data is carried, via RS-232 electrical levels, on one conductor, and target-to-controller data is carried in the other direction on the other conductor. A.
CDM-710 Broadcast Satellite Modem Remote Control Revision 10 MN/CDM710.IOM A.5.1 Start Of Packet Controller to Target: This is the character ‘<’ (ASCII code 60) Target to Controller: This is the character ‘>’ (ASCII code 62) Because this is used to provide a reliable indication of the start of packet, these two characters may not appear anywhere else within the body of the message. A.5.2 Address Up to 9999 devices can be uniquely addressed. In RS-232 applications this value is set to 0.

CDM-710 Broadcast Satellite Modem Remote Control Revision 10 MN/CDM710.IOM A.6.5 Modem Global Configuration (MGC) Command The MGC command can be used to configure the whole modem or parts of the modem. This command also contains spare bytes for future development, but the length of the command is fixed to 255 bytes. The MGC command can be used on modulator-only units, demodulator-only units, and modem units.

Appendix B. Eb/No MEASUREMENT Although the CDM-710 calculates and displays the value of receive Eb/No on the front panel of the unit, it is sometimes useful to measure the value using a spectrum analyzer, if one is available. The idea is to accurately measure the value of (Co+No)/No, (Carrier density + Noise density/Noise density).
