Comtech EF Data’s CDM-570AL and CDMR-570AL Satellite Modems are intended for L-Band closed network applications. The CDM-570A Satellite Modem is the 70/140 MHz version of the same modem. Either frequency version serves as a drop-in replacement for the CDM570L/CDMR-570L (L-Band) or CDM-570 (70/140 MHz) Satellite Modems. Apart from the IF frequency band, the modems are essentially identical. The modem is 100% backwards compatible with its predecessors, but incorporates ne w f eatures and expansion capabilities.

1.1.1 Modem Features Overview

• The CDM-570AL provides an L-Band IF frequency range from 950 to 2250 MHz.

• The CDM-570A provides a 70/140 MHz IF f requency range from 50 to 90 MHz and 100

to 180 MHz.

• The CDM-570AL consumes only 29 Watts (typical, without any option cards).

Introduction 1–1 MN-CDM570A

CDM-570A/570AL Satellite Modem with Optional Packet Processor Revision 5

• The CDM-570A/570AL may be equipped with the optional High-Performance Packet Processor

card for 10/100 BaseT Ethernet operation that, in addition to providing Layers 3-5 functionality, incorporates a number of key f eatures for Wide Area Network (WAN) bandwidth optimization: very low overhead High-level Data Link Control (HDLC); Header and Payload Compression; Advanced Quality of Service (QoS); and Triple DES (3XDES) Encryption.

• The CDM-570A/570AL offers variable data rates from 2.4 kbps to 10.239 Mbp s , in BPSK, QPSK, Offset QPSK, 8-PSK, 8-QAM, 16-QAM modes.

• The CDM-570A/570AL supports an enti rely new family of waveforms - VersaFEC-2

®.

(both short and long block Low-density Parity Che ck Coding (LDPC)) with variable data rates in BPSK, QPSK, 8-ARY, 16-ARY, and 32-ARY modes.

• The CDM-570A/570AL provides, as Fo rward Error Correction (FEC) options: Viterbi, concatenated Reed-Solomon (R-S), Trellis Coded Modulation (TCM), Turbo Product Coding (TPC, IESS-315 compliant), ULL (Ultra Low Latency), VersaFEC

(a short-block,

low latency LDPC), and VersaFEC-2.

• The CDM-570A/570AL provides a full r ange of built-in interface types, including G.703 T1 and E1 and, when the modem is equipped with the optional Packet Processor, Ethernet.

• The CDM-570A/570AL is compact – it is 1RU high, with a depth of 16 inches for the CDM-570AL, 11 inches for the CDMR-570AL Reduced Chassis Depth unit, and 13.13 inches for the CDM-570A.

• The CDM-570A/570AL features a front panel Vacuum Fluorescent Display (VFD), and six-button keypad for local Monitor and Control (M&C).

• The CDM-570A/570AL features an integrated 10/100 BaseT Ethernet interface for network-based remote product M&C – including SNMP, HTTP (non-secure Web server), and Telnet.

• The CDM-570AL supports external Block Up Converters (BUCs) and Low-noise Block Down Converters (LNBs). An optional BUC power s upply, either 90 Watts or 150 Watts @ 50°C, may be installed internally. 10 MHz reference signals are available to drive both BUC and LNB. LNB power and Frequency Shift Keying (FSK) for ‘smart’ BUCs is standard.

1.1.2 Functional Description

The modem has two fundamentally different types of interface – IF and data:

• The IF interface provides a bidirectional link with the satellite via the uplink and downlink equipment.

• The data interface is a bidirectional path that connects the modem (assumed to be t he Data Circuit-terminating Equipment (DCE)) to the custome r’s equipment (assumed to be the Data Terminal Equipment (DTE)).

Transmit data is received by the terrestrial interface where line receivers convert the clock and data signals to CMOS levels for further processi ng. A small First In First Out (FIFO) follows the terrestrial interface to facilitate the various clocking and framing options. If framing is enabled, the transmit clock and data output from the FIFO pass through t he f ramer, where the Embedded Distant-end Monitor and Control (EDMAC) overhead data is added to the main data; otherwis e, the clock and data are passed directly to the FEC encoder.

Introduction 1–2 MN-CDM570A

CDM-570A/570AL Satellite Modem with Optional Packet Processor Revision 5

In the FEC encoder, the data is differentially encoded, scrambled, and then convolutionally encoded. Following the encoder, the data is fed to t he t ransmit digital filters, which perform spectral shaping on the data signals. The resultant I and Q signals are then fed to the BPSK, QPSK/OQPSK, 8-PSK, or 16-QAM modulator. The carrier is generated by a frequency synthesizer, and the I and Q signals directly modulate this carrier to produce an IF output signal.

In both L-Band and 70/140 MHz operation, receive sig nal s are first converted to a Ultra High Frequency (UHF) for Surface Acoustic Wave (SAW) filtering, and are then down convert ed to a lower IF frequency for direct sampling in a high spee d A /D converter. An Automatic Gain Control (AGC) circuit controls the signal level presented to the A /D converter. Digital signal processing performs the final quadrature conversion to baseband followed by Nyquist filtering, carrier recovery, and symbol timing recovery. The resultant demodulated signal is fed, in soft decision form, to the selected FEC decoder (which can be Viterbi, TCM, Reed-Solomon, Turbo, VersaFEC, or VersaFEC-2, if installed).

After decoding, the recovered clock and data pass to t he de-framer (if EDMAC framing is enabled) where the overhead information is removed. Following this, the data either passes or bypasses the Plesiochronous/Doppler buffer, which has a programmable size. From here, the receive clock and data signals are routed to the terrestrial interface, and are passed to the externally connected DTE equipment.

The modem signal processing functions are perf ormed in a single, large Field-Programmable Gate Array (FPGA), which permits rapid implementation of changes, additions and enhancements in the field. These signal processi ng f unctions are controlled and monitored by a 32-bit Reduced Instruction Set Computing (RISC) microprocessor, which als o controls all front panel, serial and Ethernet interfaces.

CDM-570A/570AL Satellite Modem with Optional Packet Processor Revision 5

1.2.6 AUPC

APPENDIX E. AUPC (AUTOMATIC UPLINK POWER CONTROL)

AUPC (Automatic Uplink Power Control) is an important feature that enables the modem to automatically adjust its output power to maintain a s c onst ant the E

of the remote end of the

b/N0

satellite link. This provides protection against rain fading, a particularly severe problem with KuBand links.

Note that you can simultaneously use both EDMAC and AUPC. A benefit of AUPC is that, whenever you select EDMAC/AUPC operation, you can view the remote demodulator’s E

b/N0

from the front panel display of the local modem. To accomplish AUPC, you must use the framed EDMAC mode of operation. The dist ant end

modem constantly sends back information about the demodulator E the overhead structure. The local modem uses the E

to adjust its output power and create a

b/N0

using reserved bytes in

b/N0

closed-loop feedback system over the sat el li te link.

1.2.7 EDMAC

Appendix J. EDMAC CHANNEL

EDMAC facilitates network management for small networks. In this mode, an additional 5% overhead is combined with the traffic data, (1.6% in Turbo BPSK modes, Turbo Rate 21/44 QPSK/OQPSK, and all data rates greater than 2 Mbps). M &C information is added transparently, allowing access to the distant-end modem.

Additionally, EDMAC-2 uses 1.6% overhead in all modes for those application s where the 5% overhead is excessive. The EDMAC and EDMAC-2 modes do not require any additional cabling at either the local or the distant-end modems.

The standard M&C control port provides acce ss to EDMAC. Full monitor and control is possible, and you may control the on/off status at the dista nt-end carrier.

1.2.8 Updating Modem Firmware

Chapter 4. UPDATING FIRMWARE

The modem uses ‘flash memory’ technology internally. This simplifies firmware updating. You may perform the firmware update, without opening the modem, remotely over satellite (when

the modem is equipped with the optional Packet P rocessor), or by directly connecting a usersupplied Microsoft Windows-based PC to the modem ‘Ethernet 10/100 | M&C 100’ port (for modems without the optional Packet Proce ss or) or the ‘Ethernet 10/100 | Traffic 100’ port (for modems equipped with the optional Packet Pro cessor).

Figure 3-1. Coaxial Connector Examples

These connectors are available in two coupling st yles – Bayonet or Threaded:

• Bayonet Coupling Style – The jack has a pair of gui deposts that accommodate the plug’s lockdown slots. This lockdown design provides secure assembly without overtightening the connection.

• Threaded Coupling Style – The jack feature s ex ternal threads. The plug shell features internal threads, and has either a knurled outer surface to permit hand-tightening of the connection, or hex flats to accommodate torque d installation.

Connection Instructions:

• Bayonet Coupling Connections: Use the plug slots to guide, then slide the plug onto the jack posts. Then, turn the plug clockwise until t he j ack posts are fully seated within the plug slot.

• Threaded Coupling Connections: Engage the plug ont o t he jack threads, and then turn the plug clockwise until it is fully threaded onto the jack. Do not over-tighten the connection.

Whether its gender is male or female, the cable plug features two jack screws for secure connection to the jack nuts provided on the mating c hassis receptacle. The jack screws may be hand tightened or tightened with a standard flat-bl ade scre wdri ver.

Connection Instructions: Orient the plug to the receptacle in t he proper position. Press firmly into place. Use the jack screws to secure the plug to the re ceptacle jack nuts. Do not over-tighten.

About connector pinout tables: Figure 3-2 identifies the Pin 1 location for either gender connector. Unless noted otherwise, the connector pinout tables provided in this manual arrange/order information (i.e., the Pin # column/row) based on this orientation.

3.1.3 RJ-XX Cable Connections

The plug for an RJ-11, RJ-45, or RJ-48 cable features a flexible tab. The mating port features a slot to accept the tab. This design configuration assures proper installation and pi n orientation.

Connection Instructions: Press down the tab on the cabl e plug, and then insert the plug into the port. The connection is complete when the tab ‘cli cks’ in place inside the port.

Chapter 4. UPDATING FIRMWARE

4.1 Overview

The CDM-570A/570AL Satellite Modem is factory-shipped with its latest version of operating firmware. If you need to update the modem firmware, you may download the update from the Comtech EF Data Web site (www.comtechefdata.com). You may also receive the firmware update archive file via e-mail from Comtech EF Data Product Support.

You may perform the firmware update, without opening the CDM-570A/570AL, remotely over satellite (when the unit is equipped with the optional High Pe rf ormance Packet Processor), or by directly connecting a user-supplied Microsoft Win dows-based PC to the CDM-570A/570AL ‘Ethernet 10/100 | M&C 100’ port (for units without the optional Packet Processor) or the ‘Ethernet 10/100 | Traffic 100’ port (for units equipped with the optional Packet Processor).

In this order:

• Download the firmware update arc hive file via the Internet, or acquire the file from

Comtech EF Data Product Support, and transfer t he files to the User PC.

• Use Windows Command-line to transfer, via File Transfer Protocol (FTP), the extracted

firmware files from the User PC to the CDM-570A/570AL standby firmware image.

• Use the CDM-570A/570AL front panel or t he CDM-570A HTTP Interface to configure the

modem to operate using the updated firmware image .

firmware.

2. Ethernet IP Functionality is available only when the cdm-570A/570AL is equipped with the optional HIGH PERFORMANCE Packet Processor.
