Chapter 6. FORWARD ERROR CORRECTION 6.1 Introduction The method of Forward Error Correction (FEC) utilized by the CDM-840 Remote Router depends on the direction of signal processing in use: On the receive (Rx) side, the CDM-840 operates with error correction based upon the DVB-S2 standard for QPSK, 8PSK, 16APSK and 32APSK with concatenated Low Density Parity Code (LDPC) and Bose-Chaudhuri-Hocquenghem (BCH).
CDM-840 Remote Router Forward Error Correction Revision 0 MN-CDM840 applications this is not a drawback. Links with LDPC normally operate at multi-megabit data rates where latency effects are minimal. The standard block size for LDPC is 64,800 bits, and for lower data rate applications there is a short frame block at 16,800 bits that suffers only a small error correcting loss (0.2 to 0.5 dB) compared to the standard block. 6.2.1 Range of Data Rates For the range of Data Rates, refer to Sect. 1.

Appendix A. FAST ACTIVATION PROCEDURE A.1 Introduction The CDM-840 Remote Router is extremely flexible and powerful, and incorporates a number of optional features. In order to permit a lower initial cost, the unit may be purchased with only the desired features enabled. If, at a later date, the user wishes to upgrade the functionality of a unit, Comtech EF Data provides Fully Accessible System Topology (FAST), which permits the purchase and installation of options through special authorization codes.
CDM-840 Remote Router Appendix A A.2 Revision 0 MN-CDM840 Activation Procedure via Web Server Interface The CDM-840 available FAST options are listed – and the FAST Code entry/option activation controls are provided – via the Web Server Interface on the ‘Admin | FAST’ page. Refer to Chapter 5.5. WEB SERVER (HTTP) INTERFACE for a complete overview on CDM840 operations via this interface. A.2.
CDM-840 Remote Router Appendix A A.2.3 Revision 0 MN-CDM840 Acquire/Enter FAST Access Code Once a valid unit serial number is provided to and verified by the Comtech EF Data sales representative, Comtech EF Data Customer Support will then provide an invoice, the 20-digit FAST Access Code, and FAST option activation instructions. The user should carefully enter the FAST Access Code into the FAST Code 1 text box (provided in the FAST Upgrade section of the ‘Admin | FAST’ page), then click [Submit]. 1.

Appendix B. REMOTE CONTROL B.1 Overview This appendix describes the protocol and message command set for remote monitor and control (M&C) of the CDM-840 Remote Router. The electrical interface is an EIA-232 connection (for the control of a single device), and data is transmitted in asynchronous serial form, using ASCII characters. Control and status information is transmitted in packets of variable length in accordance with the structure and protocol defined in later sections. B.
CDM-840 Remote Router Appendix B Revision 0 MN-CDM840 The Controller, which is in charge of the process of monitor and control, is the only device that is permitted to initiate, at will, the transmission of data. Targets are only permitted to transmit when they have been specifically instructed to do so by the Controller. All bytes within a packet are printable ASCII characters, less than ASCII code 127. In this context, the Carriage Return and Line Feed characters are considered printable.
CDM-840 Remote Router Appendix B B.4.2 Revision 0 MN-CDM840 Target Address In EIA-232 applications this value is set to 0. IMPORTANT B.4.3 The Controller sends a packet with the address of a Target – the destination of the packet. When the Target responds, the address used is the same address, to indicate to the Controller the source of the packet. The Controller does not have its own address. Address Delimiter This is the “forward slash” character '/ ' (ASCII code 47). B.4.
CDM-840 Remote Router Appendix B Revision 0 MN-CDM840 2. From Target-to-Controller, the only permitted values are: Symbol B.4.6 Definition = (ASCII code 61) The ‘=’ code is used in two ways: a. If the Controller has sent a query code to a Target (Example: CMD? meaning “what’s the value of this parameter?”), the Target would respond with CMD=xxx, where xxx represents the parameter in question. b.
CDM-840 Remote Router Appendix B B.5 Revision 0 MN-CDM840 Remote Commands and Queries As explained earlier in this appendix, serial remote monitor and control is accomplished through use of a ‘Controller’ device – typically a PC or ASCII dumb terminal. An example of such a device is shown to the right. From this interface, the user may type ‘help[cr]’ or ‘?[cr]’ to display the CDM-840’s available commands and queries, and to review instructions for using the interface.
