CRS-300 1:10 Redundancy Switch Introduction Revision 16 MN/CRS300.IOM 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. The user can configure the CRS-300 to back up (replace) a Traffic modem when a Unit Fault and/or a Tx/Rx traffic Fault occurs. Intended for hub applications, the CRS-300 is compatible for use with the Comtech EF Data Modems specified in Table 1-1.

TMI Monitoring: Terrestrial user clock and data signals to and from a traffic modem are routed through a TMI via a set of relays. This is arranged so that the de-energized (unpowered) state connects the data signals directly through to the traffic modem.

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 CRS-300 1:10 Redundancy Switch. The intent of this chapter is to outline the differing methods for Ethernet-based data handling with the various modems featured throughout this manual.

CRS-300 1:10 Redundancy Switch Ethernet Network Configurations Revision 16 MN/CRS300.IOM 3.3.2 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. 3.3.2.

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.

The routers will block the broadcasts coming from the remote network. Therefore, no broadcast storm can be created or the possibility of having a remote MAC on the Hub networks. Figure 3-4.

A Static ARP Entry is needed in the switch so that routing of the Tx side of the modems will be on the correct port of the router.

CRS-300 1:10 Redundancy Switch Ethernet Network Configurations Revision 16 MN/CRS300.IOM 3.3.7 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.

These cables can be ordered at the same time the order is placed for the CRS-300. If fabricated by the customer, the cables required between each modem and Switch plug-in RMI or TMI card should be of shielded, twisted-pair construction, with the grounded shield bonded to the back shell.

Appendix B. ADDRESSING SCHEME INFORMATION B.1 Introduction to Addressing A CRS-300 1:10 Redundancy Switch provides 1:10 redundancy; that is, it is capable of controlling up to 10 traffic modems and one redundant modem. The user 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).

CRS-300 1:10 Redundancy Switch Addressing Scheme Information B.2 Revision 16 MN/CRS300.IOM Switch Addresses The permitted Switch remote control addresses are limited: • For EIA-485 connections, the only permitted addresses are 1000, 3000, 5000, and 7000. • For EIA-232, the only permitted address is 0000. Note: The Switch settings for external communications are totally independent from the internal communication between Switch and traffic modems. B.

CRS-300 1:10 Redundancy Switch Addressing Scheme Information B.3.2 Revision 16 MN/CRS300.IOM Setting Up Transceivers Configure the modems first for EDMAC operation, setting up the Remote Control Address (RCA) for local units, and ESA (EDMAC addresses) for EDMAC modems. A transceiver's address will be set automatically by its controlling modem if connected via the FSK link when the ODU enable is configured.

Appendix C. REMOTE CONTROL C.1 Overview This appendix describes the protocol and message command set for remote monitor and control of the CRS-300 1:10 Redundancy Switch. The electrical interface is either an EIA-485 multi-drop bus (for the control of many devices) or an EIA-232 connection (for the control of a single device), and data is transmitted in asynchronous serial form using ASCII characters.

CRS-300 1:10 Redundancy Switch Remote Control C.3 Revision 16 MN/CRS300.IOM EIA-232 This is a much simpler configuration in which the Controller device is connected directly to the Target via a two-wire-plus-ground connection. Controller-to-Target data is carried, via EIA-232 electrical levels, on one conductor, and Target-to-Controller data is carried in the other direction on the other conductor. C.

CRS-300 1:10 Redundancy Switch Remote Control C.5.5 Revision 16 MN/CRS300.IOM Instruction Code Qualifier This single character further qualifies the preceding instruction code. Code Qualifiers obey the following rules: 1. From Controller-to-Target, the only permitted values are: = (ASCII code 61) The = code is used as the assignment operator, and is used to indicate that the parameter defined by the preceding byte should be set to the value of the argument(s) that follow it.

CRS-300 1:10 Redundancy Switch Remote Control C.5.6 Revision 16 MN/CRS300.IOM Optional Message Arguments Arguments are not required for all messages. Arguments are ASCII codes for the characters 0 to 9 (ASCII codes 48-57), A to Z (ASCII codes 65-90), period (ASCII code 46) and comma (ASCII code 44). C.5.7 End of Packet Controller-to-Target: This is the 'Carriage Return' character (ASCII code 13).
