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:
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. Handlesat the front facilitate removal fromand 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.
DVB-S &
DSNG
Viterbi
+RS
•Encoded information is mapped for modulation.
•A modulated carrier is transmitted fromthe 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 generateclock 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 isframed and encodedin accordance with eitherthe DVB-S, DVB-DSNG, or DVB-S2 formats.

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.
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.
ows the front panel of the CDM-710 High-Speed Satellite Modem. The front panel
features (from left) Light-Emitting-Diode (LED) indicators; a keypad; and a Vacuum Fluorescent Display (VFD):
• The eight (8) LEDs indicate, in a summary fashion, the status of the unit.
• The keypad comprises six individual keyswitches. They have a positive ‘click’ action,
which provides tactile feedback. Note that, per the above figure, the initially-released
version featured switches behind a sealed membrane overlay.
The user enters data via the keypad, and messages are displayed on the VFD.
• The VFD is an active display showing two lines of 24 characters each. It produces a blue
light with adjustable brightness. Compared to a Liquid Crystal Display (LCD), the VF D
has greatly superior viewing characteristics and does not suffer problems of viewing
angle or contrast.
The function and behavior of the LED indicators, keypad, and VFD is described in detail in
Chapter 5. FRONT PANEL OPERATION.
Data interfaces are installed or removed from the rear of the CDM-710 chassis into Slot 1 and
Slot 2 of the CDM-710. The allowable combination of data interfaces and the data interfaces that
are supported for redundancy are found in the table that follows. In all cases, only one data interface is active at a time.
Additional information relating to the data interfaces supported in 1:1 and 1:N support is also
provided.
1:1 Redundancy with the CRS-170A (70/140 MHz) and CRS-180 (L-Band): The “Allowable
CDM-710 Modem Configuration” column in the table that follows shows the data interface
combinations of the modem that are supported by the CRS-170A and CRS-180 1:1 Redundancy
Switches. First, the 1:1 switch is selected depending upon the operating frequency, and then a
data interface kit for Slot 1 and Slot 2 is chosen. More information on these kits is provided in the
CRS-170A or CRS-180 1:1 Redundancy Switch datasheet and Installation and Operation manual.
1:N Redundancy with the CRS-300: The CRS-300 was originally design ed for operation with th e
CDM-600 and subsequently adapted to a number of other modems. It is capable of supporting
interfaces up to the point where there are no more p aths left to route tra ffic. This is the re ason why
the CRS-300 supports a limited set of the interface combinations supported by the CDM-710.

1.3.6 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.
1.3.7 Flash Upgrading Modem Firmware
The internal firmware is both powerful and flexible, permitting storage and retrieval of up to 10
different modem configurations. The CDM-710 uses ‘flash memory’ technology internally, and
new firmware can be uploaded to the unit from an external PC. This simplifies software
upgrading, and updates can be sent via the Internet (using www.comtechefdata.com, Comtech EF
Data’s Web site), by e-mail, or on CD. The upgrade can be performed without opening the unit
simply by connecting the CDM-710 to the Ethernet port of a computer. See Chapter 4. FLASH UPGRADING for further information.
The CDM-710 is extremely flexible and powerful, and incorporates a large number of optional
features. In order to permit a lower initial cost, the modem may be purchased with only the desired
features enabled.
If, at a later date, a user wishes to upgrade the functionality of a modem, Comtech EF Data provides
Fully Accessible System Topology (FAST), which permits the purchase and installation of options
through special authorization codes loaded into the unit eith er via the front panel key pad or entered
remotely via the remote port located on the modem rear panel.
These unique access codes may be purchased at any time from Comtech EF Data.
FAST System Theory
FAST facilitates on-location upgrade of the operating feature set without removing a modem
from the setup.
With FAST technology, operators have maximum flexibility for enabling functions as they are
required. FAST allows an operator to order a modem precisely tailored for the initial application.
When service requirements change, the operator can upgrade the topology of the modem to meet
those requirements within minutes. This accelerated upgrade ca n be accomplished because of FAST’s
extensive use of the programmable logic devices incorporated into Comtech EF Data products.
FAST Implementation
Comtech EF Data’s FAST system is factory-implemented in the modem. All FAST options are
available through the basic platform unit at the time of order – FAST allows immediate activation of
available options, after confirmation by Comtech EF Data, through the front panel keypad or via the
remote control interface.
See Appendix C. FAST ACTIVATION PROCEDURE for further information.
FAST Accessible Options
Hardware options for basic modems can be ordered and installed either at the factory or in the
field. The operator can select options that can be activated easily in the field, depending on the
current hardware configuration of the modem. A unique access code enables configuration of the
available hardware.

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
or on CD.
This chapter outlines the complete upgrading process as follows:
• New firmware can be downloaded via the Internet to an external PC.
• The upgrade can be performed without opening the CDM-710 by simply connecting the
unit to the Ethernet port of the external PC.
• Once downloaded, the firmware update is transferred via File Transfer Protocol (FTP) to
the CDM-710; the update is then activated upon modem reboot.
Figure 5-1. Flash Update via Internet
(Comtech EF Data’s Web site, Figure 5-1), via e-mail,
The upgr ade to FW12437x Fir mware Ve r. 4.0.x from an ea rlier ve rsion is a one
way upgrade path. Once an upgrade to 4.0.1 (or higher) is completed, it is no
IMPORTANT
The one-way upgrade effect is necessary because reallocation of internal memory for additional
space has resulted in an incompatibility between releases beginning with Firmware Ver. 4.0.1 and
all earlier versions.
Note the following:
• Use the flash upgrading steps provided on this page when either:

Create a temporary folder (directory) on an external PC:
•For Windows Explorer: Select File > New > Folder to create a new fol de r , the n re name it from
“New Folder” to "temp" or another convenient, unused name. Assuming "temp" works, a
"c:\temp" folder should now be created.
Note: The drive letter c: is used in this example. Any valid writable drive letter can be used.
•For Windows Command-line: Click [Start] on the Windows taskbar, then click the
“Run...” icon (or, depending on Windows OS versions prior to Windows 95, click the “MS-DOS Prompt” icon from the Main Menu). Then, to open a Command-line window…
o For Windows 95 or Windows 98 – Type “command”.
o For any Windows OS versions later
than Windows 98 – Type “cmd” or
“command”.
Alternately, from [Start], selectAll Programs > A ccessories > Command Prompt.
At the Command-line prompt (c:\>), type “mkdir temp” or “md temp” (without quotes – mkdir
and md stand for make directory). This is the same as creating a new folder using Windows
Explorer. There should now be a "c:\temp" subdirectory created (where c: is the dr ive letter used in
this example).

Download the correct firmware file to this temporary folder. As shown in Figure 4-1:
a) Go online to: www.comtechefdata.com
;
b) From the Home page menu bar, click the Support tab;
c) Click the Software Downloads drop-down or hyperlink from the Support page;
d) Click the Download Flash and Software Update Files icon;
e) Click the (Select a Product Line:) SatelliteModems hyperlink provided on the Fl ash a n d
Software Update Files page;
f) Select the CDM-710 product hyperlink from the Comtech Brand column;
About Firmware Numbers, File Versions, and Formats: The flashable files on the
download server are organized by product prefix (i.e., FW – Firmware).
The base modem bulk firmware for the CDM-710 is FW12437x_V### (where ‘x’ denotes the
revision letter of the bulk modem firmware, and V### represents the firmware version),
applicable for units with the Rev A. or later chassis (FW Ver 2.1.1 or later); for initiallyreleased chassis (with the membrane overly switch assembly, FW Ver. 1.1.3 or earlier), the
based modem bulk firmware number is FW12050x_V###.
The current version firmware release is provided. If applicable, one version prior to the
current release is also available. Be sure to identify and download the desired version.
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 ZipCentral h elp files. PKZIP for DOS is not supported due to file
naming conventions.
Extract the files to the temporary folder on the PC.
A minimum of two files should be extracted:
1. FW12437x.bin, where "x" denotes the revision letter for the bulk image file.
2. ReleaseNotes_CDM710_v###.pdf, where “###” denotes the firmware release version
number .
Confirm that the files have been extracted to the specified temporary folder on the PC. Using
Command-line, type cd c:\temp to change to the temporary directory created in Step 2, then use the dir command to list the files extracted from the downloaded archive file.

Initiate an FTP session with the modem. Using Command-line:
a) From the PC, at the prompt type "ftp www.xxx.yyy.zzz" where "www.xxx.yyy.zzz" is the IP
address of the base modem.
b) Enter the Admin User Name (there will be no prompt for a password) to complete login.
c) Verify the FTP transfer is binary by typing "bin".
d) Type "prompt", then type "hash" to facilitate the file transfers.
