Page 23: Chapter 1. Introduction
Chapter 1. INTRODUCTION 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.
Page 24: Standard And Optional Features
CDM-710 Broadcast Satellite Modem Revision 9 Introduction 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.
Page 25: Software - Flash Upgrading
CDM-710 Broadcast Satellite Modem Revision 9 Introduction MN/CDM710.IOM 1.1.1 Software – Flash Upgrading The internal software is both powerful and flexible, permitting storage and retrieval of up to 10 different configurations. The modem uses ‘flash memory’ technology internally, and new firmware is uploaded to the unit from an external PC.

Page 31: Chapter 3. Functional And Physical Descriptions
Chapter 3. FUNCTIONAL AND PHYSICAL DESCRIPTIONS 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.
Page 32: Front Panel
CDM-710 Broadcast Satellite Modem Revision 9 Functional and Physical Description 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.

Chapter 7. FORWARD ERROR CORRECTION OPTIONS 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).
Page 104: Ldpc And Bch
CDM-710 Broadcast Satellite Modem Revision 9 Forward Error Correction Options MN/CDM710.IOM LDPC and BCH LDPC and BCH is also concatenated technique. LDPC is a very powerful coding scheme with significant, near Shannon bound, performance. In some cases, as the carrier to noise ratio increases, the LDPC error correction starts flaring toward an error floor so BCH error correction follows LDPC and eliminates the flare for any practical range of error rates.

The CDM-710 SNMP agent supports both SNMPv1 and v2c. For proper SNMP operation, the CDM-710 MIB files must be used with the associated version of the CDM-710 modem M&C Software. Refer to the CDM-710 SW Release Notes for information on the required FW/SW compatibility.
Page 128 These MIB files should be compiled in a MIB Browser or SNMP Network Monitoring System server. Note: The CDM-710 SNMP agent supports both SNMPv1 and v2c. The CDM-710 Traps file only needs to be compiled if SNMPv1 traps are to be used.

All of the targets receive the packet, but only one (the intended) will reply.

Page 166: Instruction Code
CDM-710 Satellite Modulator Revision 9 Remote Control MN/CDM710.IOM A.5.3 Instruction Code This is a three-character alphabetic sequence which identifies the subject of the message. Wherever possible, the instruction codes have been chosen to have some significance. For example TFQ for transmit frequency, etc. This aids in the readability of the message, should it be displayed in its raw ASCII form.
Page 167: Message Arguments
CDM-710 Satellite Modulator Revision 9 Remote Control MN/CDM710.IOM First, if the controller has sent a query code to a target (for example TFQ?, meaning ‘what’s the Transmit frequency?’), the target would respond with TFQ=xxxx.xxxx, where xxxx.xxxx represents the frequency in question.

Page 242 CDM-710 Broadcast Satellite Modem Revision 9 Eb/No Measurement MN/CDM710.IOM The idea is to accurately measure the value of (Co+No)/No, (Carrier density + Noise density/Noise density). This is accomplished by tuning the center frequency of the Spectrum analyzer to the signal of interest, and measuring the difference between the peak spectral density of the signal (the flat part of the spectrum shown) and the noise density.
