  • Page 25: Chapter 1. Introduction

    The CRS-300 1:10 Redundancy Switch (referred to throughout this manual as the Switch) provides fully automatic protection of traffic circuits in the case of equipment failure. You can configure the CRS-300 to back up (replace) a Traffic modem when a Unit Fault and/or a Tx/Rx Traffic Fault occurs.
  • Page 26 Introduction Revision 19 The CRS-300 is intended for hub applications. It is compatible for use with the Comtech EF Data modems specified in Table 1-1. While the Switch is capable of controlling any of these modems, note that it is important that only one type of modem may be connected to the Switch within a given redundancy system;...

    CRS-300 has "timed-out" and there was no response from the other device. During this wait, do not communicate with the CRS-300. After the '~' response is sent by the CRS-300, it is now ready to receive a message again.

  • Page 231: Appendix A. Ethernet Network Configurations

    For operations requiring Ethernet-based terrestrial data handling, it is important to emphasize the need for you to avoid Ethernet looping connection problems – with or without use of the CRS-300 1:10 Redundancy Switch. The intent of this appendix is to outline the differing methods for Ethernet-based data handling with the various modems featured throughout this manual.

    Rx and Tx Ethernet traffic using different ports of the same router or switch. Each application also has CRS-300 Redundancy applications examples, with subsequent sections in this appendix providing examples of applications architecture designed to handle near-to-far end Ethernet network configurations.

  • Page 233: Ethernet Redundancy With Crs-300

    After the customer has determined the best configuration for near-to-far end Ethernet networks, the CRS-300 1:10 Redundancy Switch may now be added to one or both ends of the link(s). Ethernet redundancy using the CRS-300 can be accomplished using a wired-thru or wired-around configuration.

    A wired-around Ethernet redundancy example is shown for the CDM-700 User in Figure A-4. When the CRS-300 1:10 Redundancy Switch backs up a faulted Traffic Modem, the physical port on the router needs to change from the Traffic Modem port to the Redundant Modem port.

    SCHEME INFORMATION Addressing Overview A CRS-300 1:10 Redundancy Switch provides 1:10 redundancy; that is, you may use the CRS-300 to control one Redundant Modem and up to 10 Traffic Modems. You can remotely communicate to the Switch or any of the modems, via the DB-9, EIA-232 or EIA-485 remote connector on the CRS-230 Switch Controller card (installed in the CRS-300).

    CDM-Qx/QxL modems require an external multi-drop EIA-485 connection. Figure C-5 shows the external EIA-232 addressing scheme for a system comprising these modems with a Switch; Figure C-6 depicts the external EIA-485 connection for this configuration. See Figure C-7 for a distant-end CRS-300/Qx/QxL setup using Traffic modems in EDMAC Slave Mode. C–2...
