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. The operating frequency of the CDM-710 is available in the following versions: CDM-710 (70/140 MHz) 52 to 88 MHz and 104 to 176 MHz in 100 Hz resolution.
CDM-710 Broadcast Satellite Modem Introduction Revision 11 MN/CDM710.IOM The CDM-710 is compact, being 1RU high x 18.65 inches deep, with low power consumption. It has a front panel Vacuum Fluorescent Display (VFD) and keypad for local configuration and control, although it can be fully remote-controlled via its RS-485 bus or 10/100 Base-T Ethernet Interface. 1.1.
CDM-710 Broadcast Satellite Modem Introduction Revision 11 MN/CDM710.IOM The CDM-710 is constructed as a 1RU-high rack-mounting chassis, which can be freestanding, if desired. Handles at the front facilitate removal from and placement into a rack. The CDM-710 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.

Chapter 4. FLASH UPGRADING 4.1 Flash Upgrading via Internet The CDM-710 Broadcast Satellite Modem eliminates the need for updating firmware by physically replacing EPROMs. Instead, the CDM-710 uses ‘Flash memory’ technology internally. This makes software upgrading very simple, and updates can now be sent via the Internet using www.comtechefdata.com (Comtech EF Data’s Web site, Figure 5-1), via e-mail, or on CD.
CDM-710 Broadcast Satellite Modem Flash Upgrading 4.2 Revision 11 MN/CDM710.IOM CDM-710 Broadcast Satellite Modem Flash Upgrade Restrictions IMPORTANT The upgrade to FW12437x Firmware Ver. 4.0.x from an earlier version is a one way upgrade path. Once an upgrade to 4.0.1 (or higher) is completed, it is no longer possible to revert to earlier versions – if reflash to an earlier version is attempted the modem will detect and disallow it as a protective measure.

Chapter 6. ETHERNET MANAGEMENT 6.1 Introduction The CDM-710 base modem is equipped with an RJ-45 10/100 Base-T Ethernet management interface used for monitor and control purposes. This chapter provides information for the functionality provided by this interface, and references other chapters in this manual for further details. 6.
CDM-710 Broadcast Satellite Modem Ethernet Management 6.3 Revision 11 MN/CDM710.IOM SNMP Interface The Simple Network Management Protocol (SNMP) is an application-layer protocol designed to facilitate the exchange of management information between network devices. The CDM-710 SNMP agent supports both SNMPv1 and v2c. IMPORTANT For proper SNMP operation, the CDM-710 MIB files must be used with the associated version of the CDM-710 modem M&C.
CDM-710 Broadcast Satellite Modem Ethernet Management 6.3.1.1 Revision 11 MN/CDM710.IOM Common Private MIBs The CDM-710 SNMP agent also implements four private MIBs. The CDM-710 Common MIB holds all unit parameters not associated with Modulator, Demodulator, FEC, or Interface boards. For detailed OID information please refer to the actual MIB file. 6.3.1.
CDM-710 Broadcast Satellite Modem Ethernet Management 6.3.1.6 Revision 11 MN/CDM710.IOM HSSI MIB SNMP for the HSSI interface is not supported at this time. 6.3.2 SNMP Community Strings The CDM-710 uses community strings as a password scheme that provides authentication before gaining access to the modem agent’s MIBs. In “SNMP v1/v2c”, the community string is sent unencrypted in the SNMP packets.

CDM-710 Broadcast Satellite Modem Ethernet Management Revision 11 MN/CDM710.IOM response (for example, FRW? response) will be displayed as one line, with the latter lines overwriting the previous lines. In order to view the full response messages, CEFD recommends using HyperTerminal configured as Telnet Client. To do so, configure HyperTerminal as follows: 1. Ensure that connection is made using TCP/IP (Winsock) instead of COM1 or COM2, as shown in the example to the near right. 2.
CDM-710 Broadcast Satellite Modem Ethernet Management Revision 11 MN/CDM710.IOM 6.4.2 Using Telnet Refer to Appendix A. REMOTE CONTROL in this manual for the syntax and list of commands and status queries for the modem. Telnet is implemented in the modem Ethernet M&C in a "Telnet wrapper". When the user Telnets to the modem, it emulates a local RS-232 (RS-485) serial connection to the modem.

Chapter 7. FORWARD ERROR CORRECTION OPTIONS 7.1 Introduction The CDM-710 Broadcast Satellite 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 11 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 11 MN/CDM710.IOM 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 = 1.15 x Symbol Rate, for 25% Rolloff = 1.12 x Symbol Rate, for 20% Rolloff Table 7-1 provides the Eb/No, spectral efficiency and occupied bandwidth for the CDM-710.

Appendix A. REMOTE CONTROL A.1 Overview 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 EIA-485 multi-drop bus (for the control of many devices) or an EIA-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 Appendix A Revision 11 MN/CDM710.IOM EIA-485 (full duplex) summary: • • • A.3 Two differential pairs: one pair for Controller-to-Target, one pair for Target -to-Controller. Controller-to-Target pair has one line driver (Controller), and all Targets have line-receivers. Target-to-Controller pair has one line receiver (Controller), and all Targets have tri-state drivers.

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).
CDM-710 Broadcast Satellite Modem Eb/No Measurement Revision 11 MN/CDM710.IOM Example: In the diagram that follows, the (Co+No)/No measured is 4.6 dB. If Rate 1/2 QPSK is used, this corresponds to an Eb/No of approximately 2.8 dB (DVB-S2) or 3.1 dB (DVB-S).
