Chapter 3. ETHERNET NETWORK CONFIGURATIONS 3.1 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-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. 3.

CDM-710G High-Speed Satellite Modem Ethernet Network Configurations Revision 1 MN-CDM710G 3.3.3 Hub-to-Hub with Standard Traffic using Switches When connecting two or more “hub-sites” where there are multi-paths between each site, care must be taken to ensure no network loops occur. Figure 3-2 depicts two hub-sites connected with two or more modems where all the traffic being transmitted and received is on the same LAN/VLAN. Figure 3-3 shows a simplified version of the Networking Loop.

CDM-710G High-Speed Satellite Modem Ethernet Network Configurations 3.3.7 Revision 1 MN-CDM710G Hub-to-Remotes, Split-path Traffic using Switches (Point-to-Multipoint) With switches used, the hub and remote are on the same subnet as shown in Figure 3-13, meaning that broadcasts will be allowed to transverse the network. Learning Mode must be disabled on the Hub Tx/Rx modem, because if a computer on the remote sends a broadcast out to the Hub, the modem learns that MAC is local – when in fact it is not.

FLASH UPGRADING 5.1 Flash Updating via Internet The CDM-710G High-Speed Satellite Modem eliminates the need for updating firmware by physically replacing EPROMs. Instead, the CDM-710G uses ‘Flash memory’ technology internally. This makes software upgrading very simple, and updates can now be sent via the Internet (Figure 5-1), via E-mail, or on CD. This chapter outlines the complete upgrading process as follows: • New firmware can be downloaded via the Internet to an external PC.

Chapter 10. CLOCK MODES 10.1 Introduction This chapter describes the various clocking options that are available with the CDM-710G HighSpeed Satellite Modem. The CDM-710G allows the operation of single ports on single data interfaces plugged into the two slots at the rear of the modem. For the most part, each port operates independently and generally does the clocking for each port. When dealing with satellite modems, the subject of clocking often becomes a complex issue.
PAGE 156
CDM-710G High-Speed Satellite Modem Clock Modes Revision 1 MN-CDM710G Rx LoopTimed In Rx Loop-Timed applications, ST is derived from the Rx-Sat clock. Depending upon the interface, the Tx clock and Rx clock may be the same or different rates. Buffer Enabled When the Rx Buffer is enabled, one of several clocks is available to clock receive data out of the modem and send the received data to the DTE, depending upon the data interface.

CDM-710G High-Speed Satellite Modem Clock Modes Revision 1 MN-CDM710G When the Rx Buffer is enabled the Rx clock selections are as follows: Rx-Sat (default) Effectively disables the Rx Buffer because the input and output clocks are the same. Normally, the Rx Buffer is set for minimum when Rx-Sat is selected. This is the selection usually used with routers. Tx-Terr Uses the clock from the Tx input (TT) to clock out the Rx Buffer.

Appendix B. Eb/No MEASUREMENT Although the CDM-710G calculates and displays the value of receive Eb/No 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).
