  • Page 53: Chapter 3. Ethernet Network Configurations

    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-710G in redundancy. These issues are specifically addressed with a CDM-710G redundancy configuration that uses Comtech EF Data’s CRS-300 1:10 Redundancy Switch.

  • Page 54: Ethernet Configuration Examples

    CDM-710G High-Speed Satellite Modem Revision 1 Ethernet Network Configurations MN-CDM710G 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 55: Ethernet Redundancy With Crs-300

    This redundancy approach is not recommended. IMPORTANT The wired-around Ethernet connection is used with the CDM-710G 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.

    Viterbi and Reed Solomon coding. The CDM-710G High-Speed Satellite Modem operates with error correction base upon the DVB- S2 standard: QPSK, 8PSK, 16APSK and 32APSK with concatenated Low Density Parity Code (LDPC) and Bose-Chaudhuri-Hocquenghem (BCH).

  • Page 162: Range Of Data Rates

    The other difference is the use of PER (packet error rate) based upon a 188 or 204 byte MPEG frame size instead of BER (bit error rate). Note: The CDM-710G uses only a 188 byte MPEG frame size. Also, note the use of Es/No instead of Eb/No. When links operate at constant symbol rate so this is good method for comparing the performance of different modulation types and code rates.

    Overview This appendix describes the protocol and message command set for remote monitor and control of the CDM-710G High-Speed Satellite Modem. The electrical interface is either an RS-485 multi-drop bus (for the control of many devices) or an RS-232 connection (for the control of a single device), and data is transmitted in asynchronous serial form, using ASCII characters.
