    The CRS-500 is Comtech EF Data’s next generation 1:N Redundancy System. The modular CRS-500 1:N Redundancy System (Figure 1-1) comprises a Control Switch Unit (CSU), a Data Switch Unit (DSU), and an optional CRS-280 (70/140 MHz) or CRS-280L (L-Band) IF Switch Unit (ISU).

    Figure 1-2 shows the system level block diagram of the CRS-500 1:N Redundancy System, including the optional CRS-500 ISU. A key feature of the CRS-500 architecture is its ability to allow the Redundant Modem to ‘bridge’ a Traffic Modem. The CRS-500 can be configured to back up (replace) a Traffic modem when a Unit Fault and/or a Tx/Rx traffic Fault occurs.

    A Light Emitting Diode (LED) summary panel shows switch and modem status, bridge and online/offline status Construction Features: The CRS-500 is modular in construction. The DSU utilizes a Redundant Modem Interface (RMI) and TMIs – replaceable modules that are installed into slots in the DSU front panel. Ease of Connection: Connection to the Traffic modems and Redundant Modem is remarkably easy –...

    Rack Handles Figure 1-3. CRS-500 Control Switch Unit The CRS-500 CSU (Figure 1-3) is constructed as a 1RU-high, rack mount chassis, which can be free-standing, if desired. Rack handles at the front (Feature 1F) ease placement into and removal from a rack. This provides maximum control of the Redundancy System in the smallest amount of front-side rack space.

    When the entire group of modems is connected to the same transponder, you may bypass using the CRS-280/280L ISU and, in its place, passively combine or split the modulator outputs and demodulator inputs. In these applications, the CRS-500 mutes the offline modem’s Tx carrier and enables the online modem’s Tx carrier.

    FW/SW compatibility. The CRS-500 uses Community Strings as a password scheme that provides authentication before gaining access to the CRS-500 MIBs. They are used to authenticate users and determine access privileges to the SNMP agent. Type the SNMP Community String into the user-supplied MIB Browser or Network Node Management software.

    Ethernet M&C "unwraps" the Telnet packet and sends it on to the CRS-500 system, which responds to it as if it was a serial remote command.

    CRS-500 1:N Redundancy System Revision 4 9.3.2 Using HyperTerminal for Telnet Remote Control Operation Figure 9-2. Telnet Interface Example – HyperTerminal There is a disadvantage when using Windows Command line as a Telnet client with the optional Remote Control protocol. For the messages coming from the Telnet Server, Command line cannot translate a carriage return command (\r) to a carriage return + line feed command (\r\n).

    CRS-500 1:N Redundancy System Revision 4 10.2 Remote Control Protocol and Structure The electrical interface is either an EIA-232 connection (for the control of a single device) or an EIA-485 multi-drop bus (for the control of many devices). Data is transmitted in asynchronous serial form using ASCII characters. Control and status information is transmitted in packets of variable length in accordance with the structure and protocol defined in this chapter.
