Do not use any cutting tool that will extend more than 1” into the container and cause damage to the unit.

  • Page 32: Mounting

    MN/CDM700.IOM Mounting If the CDM-700 is to be mounted in a rack, ensure that there is adequate clearance for ventilation, particularly at the sides. In rack systems where there is high heat dissipation, forced air-cooling must be provided by top or bottom mounted fans or blowers. Under no circumstance should the highest internal rack temperature be allowed to exceed 50°C (122°F).

  • Page 127: Introduction

    Codes have been developed: Turbo Convolutional Codes (TCC), and Turbo Product Codes (TPC), a block coding technique. Comtech EF Data has chosen to implement an FEC codec based on TPC. A TPC is a 2- or 3-dimensional array of block codes. Encoding is relatively straightforward, but decoding is a very complex process requiring multiple iterations of processing for maximum performance to be achieved.

  • Page 128: Range Of Data Rates

    Forward Error Correction Options MN/CDM700.IOM With the CDM-700, Comtech EF Data now provides one of the best FEC technologies currently available. For high data rate operation the higher code rates are preferred to minimize the required bandwidth. This offering provides the range of TPC code rates in combination with QPSK, 8-PSK, 16-QAM and 64-QAM modulation.

  • Page 193: Introduction

    For operations requiring Ethernet-based terrestrial data handling, it is important to emphasize the need for Users to avoid Ethernet looping connection problems – with or without use of the CDM-700 in redundancy. These issues are specifically addressed with a CDM-700 redundancy configuration that uses Comtech EF Data’s CRS-300 1:10 Redundancy Switch.

  • Page 194: Ethernet Configuration Examples

    CDM-700 High Speed Satellite Modem Revision 5 Ethernet Network Configurations MN/CDM700.IOM 14.3 Ethernet Configuration Examples This section explains the problems with Ethernet Networking Loops, and how to properly design applications architecture for handling Standard traffic and Split-path traffic. Standard traffic is defined as Rx and Tx Ethernet traffic using the same port on the same router or switch, whereas split-path traffic is Rx and Tx Ethernet traffic using different ports of the same router or switch.

  • Page 195: Ethernet Redundancy With Crs-300

    This redundancy approach is not recommended. IMPORTANT The wired-around Ethernet connection is used with the CDM-700 modem and CRS-300 1:10 Redundancy Switch, where both modem data interface slots are needed; e.g., where one slot is HSSI or G.703 and the other slot is GigE. With the Ethernet slot configured for the wired-around method, this gives full redundancy capability to both data slots.

    Appendix F. E MEASUREMENT Although the CDM-700 calculates and displays the value of receive E on the front panel of the unit, it is sometimes useful to measure the value using a spectrum analyzer, if one is available. The idea is to accurately measure the value of (Co+No)/No, (Carrier density + Noise density/Noise density).
