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:
Chapter 1. INTRODUCTION
CDM-710 (70/140 MHz)
CDM-710L (L-Band)
Individual Modulator and Demodulator cards are available for the CDM-710 for operation at
either 70 /140 MHz or L-Band. The terrestrial data interfaces, as depicted in the block diagram
shown in Figure 1-2, are field removable to allow different interface types:
• CDI-40 Duplex ASI Interface
• CDI-60 HSSI Interface
• CDI-70 1000 Base-T Gigabit Ethernet (GbE) Ethernet Interface
52 to 88 MHz and 104 to 176 MHz in 100 Hz resolution.
950 to 2000 MHz in 100 Hz resolution.

CDM-710 Broadcast Satellite Modem Revision 11
Introduction 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.
1.1.1 Standard and Optional Features
The CDM-710 operates in DVB-S (QPSK), DVB-DSNG (8-PSK and 16-QAM) and DVB-S2
(QPSK, 8-PSK, 16-APSK, and 32-APSK) modes. The modem is operated from the front panel
using the keypad and display or remote controlled via an RS-232 / RS-485 2/4 Wire bus or
10/100 Base-T Ethernet port located on the base modem.
The modem is available for ei ther 70/140 MHz or L-Band applications. The standard 70/140 MHz
Tx-IF port has a BNC female connector that is programmable for either with 50Ω or 75Ω
impedance operations. Spectral rolloffs of 20, 25, and 35% are available.
1.2 Functional Description
A block diagram of the CDM-710 is shown in Figure 1-2.
Figure 1-2. CDM-710 Block Diagram
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 rac k.
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.
DVB-S &
DSNG
Viterbi
+RS
• Encoded information is mapped for modulation.
• A modulated carrier is transmitted from the IF interface for use by uplink equipment for
delivery to the satellite.
• A carrier received from the satellite link is acquired and demodulated to recover symbols
and timing.
• Error correction and deframing are performed.
• User data is delivered to the to the data interface.
Transmit (Tx) data is delivered to the data interface where it is converted to clock and data
signals for further processing. Depending upon the type of interface, clock and data are provided
or in other cases the clock is embedded in the data and clock recovery is performed to generate
clock and data signals.
A First-In–First-Out (FIFO) follows the terrestrial interface to facilitate delivery of the data to the
framing card. Data is passed to the Forward Error Correction (FEC) Encoder where the data is
framed and encoded in accordance with either the DVB-S, DVB-DSNG, or DVB-S2 formats.

CDM-710 Broadcast Satellite Modem Revision 11
Introduction 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.
• Encoded information is mapped for modulation.
• A modulated carrier is transmitted from the IF interface for use by uplink equipment for
delivery to the satellite.
• A carrier received from the satellite link is acquired and demodulated to recover symbols
and timing.
• Error correction and deframing are performed.
• User data is delivered to the to the data interface.
Transmit (Tx) data is delivered to the data interface where it is convert ed to clock and data signals
for further processing. Depending upon the type of interface, clock and data are provided or in other
cases the clock is embedded in the data and clock recovery is performed to generate clock and data
signals.
A First-In –First-Out (FIFO) follows the terrestrial interface to facilitate delivery of the data to the
framing card. Data is passed to the Forward Error Correction (FEC) Encoder where the data is
framed and encoded in accordance with either the DVB-S, DVB-DSNG, or DVB-S2 formats.
After encoding the data is passed to the modulator where the I and Q signals are mapped to generate
the appropriate constellation (QPSK, 8-PSK, 16-QAM, 16-APSK, and 32-APSK) and filtered to
provide the desired spectral rolloff.
Finally, a carrier is generated by a frequency synthesizer in conjun ction with the I and Q signals to
produce a frequency range as follows:
CDM-710 (70/140 MHz):
CDM-710L (L-Band):
52 to 88 or 104 to 176 MHz IF output signal at the connector on the
modem.
950 to 2000 MHz output signal at the Frequency connector on the
modem.
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.

1.3 CDM-710 Broadcast Satellite Modem Features
1.3.1 Physical Description
Constructed as a 1RU-high rack-mount chassis, the CDM-710 can be free-standing if desired.
Handles at the front facilitate removal from and placement into a rack.
The operator may configure and monitor the CDM-710 from the front panel, or through the
remote M&C port. Control and status is provided through the RS-232, RS-485 (2Wire or 4Wire)
port or 10/100 Base-T Ethernet port. The management Ethernet port supports SNMP, Telnet and
HTTP (Web browser) operation.
The CDM-710 is physically comprised of several main card assemblies:
• The Data Interface card is a plug-in module that is readily installed or removed at the rear
of the unit.
Note: Power must be turned off to remove or install the data interfaces. Any attempt to
remove or install a data face without first turning off the power to the unit will result in
damage to the data interface.
• The Framer Card receives signals from the data interface card and routes signals to the
FEC Encoder and Modulator. The microcontroller for the unit also resides on the Framer
Card and is the embedded controller for the entire modem. The microcontrollers handle
all of the monitor and control for the unit including the front panel keypad and display,
the RS-232 and RS-485 2Wire/4Wire remote port, and the 10/100 Ethernet port. Interface
with the other the modules in the modem is provided by the framer assembly.
• The FEC Encoder card is a plug-in module that resides on the Framer card. It generates
the encoded stream used by the modulator card.
• The Modulator card plugs into the framer card. It maps and spectrally shapes the I&Q
data for delivery to the IF interface.
• The Demodulator card also plugs into the framer. It recovers the selected carrier,
performs error correction and delivers data stream to the framer card.
