Page 24 Switch system; this is because the redundant modem must operate identically to the configured traffic modem. A key feature of the CRS-300 architecture is its ability to allow the redundant modem to ‘bridge’ a traffic modem. The Switch automatically configures the redundant modem to match the bridged modem’s configuration.
Page 25 TMI is removed, no interruption of the traffic occurs. It should also be noted that, in normal circumstances where the redundant modem is not in service, no data is carried through the CRS-300 backplane – all data is routed via the TMI. CRS-350 Option: Where protection of the IDR overhead signals (backward alarms, audio ESC, data ESC, etc.) is desired, the CRS-350 module may be added.

1.4.2 Rear Panel Figure 1-4 shows the back panel of the CRS-300 with a typically configured mix of TMI cards. Because the RMI can have the capability for several TMIs, depending on user requirements the CRS-300 may be able to use several different TMI cards simultaneously.

Page 46: Figure 2-1. Typical Rack Mounting Configuration
It is important to ensure that there is adequate clearance for ventilation in the rack. Since the Switch itself is relatively passive, no additional clearance is needed between it and the nearest modem. In rack systems where there is high heat dissipation, provide forced-air cooling by installing top- or bottom-mounted fans or blowers.
Page 47: Chapter 3. Ethernet Network Configurations
An Ethernet switch maintains what is known as a CAM (Content Addressable Memory) table, listing the MAC addresses for each switch port. The Ethernet switch uses the CAM table to determine where to forward Ethernet frames. By default, Ethernet switches will update the CAM table automatically;...

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 49: 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.

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.

Redundancy Switch uses the CRS-310 Redundant Modem Interface (RMI) for all driving traffic configurations. When using the CDM-625 in a CRS-300 1:10 Redundancy system, TMIs may be mixed within the same CRS-300 with some limitations: while the “P2” (DB-15M) connector on the CRS-310 RMI may be used for Balanced / Unbalanced G.703 or Quad E1 traffic, only one of these two...

Required Control Cabling (Regardless of Driving Traffic Data Type) For RMI connections: The Control/Data Cable CA/WR0066 (DB-25F to DB-25M, 6’) provides the serial communication path between the Redundant CDM-625 and the CRS-300 (via the CRS-310 RMI) for all driving traffic data types, and is therefore always required.

Page 89: Ethernet Data Connections
IMPORTANT The wired-thru Ethernet connection on the CRS-300 is the easiest and simplest choice for Ethernet redundancy. This connection method – the same as used on the standard serial data interface – provides a single connection (i.e., using one of four available RJ-45 ports) for the User Data Interface and provides simple Form-C relays that route the Ethernet connection from the User connection to either the Traffic or Redundant Modem.
Page 90: Ethernet Data Connection - Wired-Around Method (Sub-Mux)
Where the CDM-625 Sub-Mux mode will be used, the wired-around Ethernet connection is used with the CDM-625 modem and CRS-300. With Ethernet Bridge Mode configured for the wired- around method, this gives full redundancy capability to both selected data types in Sub-Mux mode.

5.5.3.3 Set Operation Mode The CRS-300 is shipped in the Auto-Off (i.e. Manual) operating mode . This setting causes the Stored Event LED to blink. The system is operational; however, it is still operating in mode. In the menu, this manual mode is called manually select which Traffic Modem will be bridged or backed-up.
Page 167: Set Holdoff Period
2) Is the Redundant Modem not exhibiting the same fault? If the answer is yes to both questions for the entire backup holdoff time, then the Switch first bridges the faulted modem with the Redundant Modem. If the fault is sustained, then the switchover to the Redundant Modem is completed and the Redundant Modem carries the traffic.
Page 168: Set Restore Holdoff Period
Another way to adjust the Switch's reaction in Auto mode is to mask modem faults. The User may disable modem Rx, Tx or both fault types so that the Switch does not react to them. This masking prevents the Switch from taking automatic action and prevents the logging of the faults in the stored events list.

Page 239: Appendix B. Addressing Scheme Information
SCHEME INFORMATION 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).
Page 240: Switch Addresses
EIA-232 addressing scheme for a system comprising these modems with a Switch; Figure B-4 depicts the external EIA-485 connection for this configuration. For a distant- end CRS-300/Qx Switch using Traffic modems in EDMAC Slave mode, refer to Figure B-5. The CDM-570/570L, CDM-600/600L and CDM-625 modems utilize point-to-point internal serial communication bus to the Switch within the DB-25 or DB-9 cable.

Page 250: Setting Up Transceivers
CRS-300 1:10 Redundancy Switch Addressing Scheme Information B.3.2 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 IMPORTANT modem if connected via the FSK link when the ODU enable is configured.
Page 251: Appendix C. Remote Control
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.
Page 252: Basic Protocol
C.4.1 Rules for Remote Serial Communications with the CRS-300 1. Always wait for a response (up to 15 seconds) from the CRS-300 before sending the next query or command. 2. If a "time-out" response ('~') is sent from the CRS-300, the user must resend the previous command.
Page 253: Packet Structure
C.5.2 Target Address While up to 9,999 devices can be uniquely addressed, connection to the CRS-300 imposes some basic limitations: • In EIA-232 applications, the Switch address is fixed at 0000.
Page 254: Address Delimiter
For example, BKH is for BacKup Hold-off time; SID is for Switch ID, etc. This aids in the readability of the message if seen in its raw ASCII form. Only upper case alphabetic characters may be used (A-Z, ASCII codes 65-90).
Page 255: Instruction Code Qualifier
BKH# (with no message arguments). The ∼ code is only used as follows: If a message was sent via the Switch to an attached modem or ODU, the message was transmitted transparently through the Switch. In the event of the other device not responding, the Switch would generate a response e.g.
Page 256: Optional Message Arguments
CRS-300 1:10 Redundancy Switch Remote Control C.5.6 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).
