Chapter 5. ETHERNET-BASED REMOTE PRODUCT MANAGEMENT 5.1 Introduction Ethernet‐based Remote Product Management of the CDD‐880 is available using the rear panel ‘ETHERNET | TRAFFIC / MANAGEMENT | GE’ RJ‐45 10/100/1000 BaseT Gigabit Ethernet traffic and M&C port. 1. TO PROCEED WITH ETHERNET‐BASED REMOTE PRODUCT MANAGEMENT (SNMP OR WEB SERVER), ASSUMPTIONS ARE MADE THAT: • The CDD‐880 is operating with the latest version firmware files.
CDD-880 Multi Receiver Router Ethernet-based Remote Product Management 5.2 Revision 1 MN-CDD880 Ethernet Management Interface Protocols The user PC facilitates access to Ethernet‐based remote monitor and control (M&C) of the CDD‐880 through two separately‐operated protocols: • Simple Network Management Protocol (SNMP). This requires a user‐supplied Network Management System (NMS) and a user‐supplied Management Information Base (MIB) File Browser. • The CDD‐880 Web Server (HTTP) Interface.
CDD-880 Multi Receiver Router Ethernet-based Remote Product Management 5.3 Revision 1 MN-CDD880 SNMP Interface The Simple Network Management Protocol (SNMP) is an Internet‐standard protocol for managing devices on IP networks. An SNMP‐managed network consists of three key components: • The managed device. This includes the CDM‐840 Remote Router. • The SNMP Agent. The software that runs on the CDM‐840. The CDM‐840 SNMP Agent supports both SNMPv1 and SNMPv2c.
CDD-880 Multi Receiver Router Ethernet-based Remote Product Management Revision 1 MN-CDD880 The user defines two Community Strings for SNMP access: • Read Community default = public • Write Community default = private For proper SNMP operation, the CDD‐880 MIB files must be used with the associated version of the CDD‐880 router M&C. Refer to the CDD‐880 FW Release Notes for information on the required FW/SW compatibility. 5.

Chapter 6. SERIAL-BASED REMOTE PRODUCT MANAGEMENT 6.1 Introduction 1. To proceed with Serial‐based Remote Product Management, assumptions are made that: • The CDD‐880 is operating with the latest version firmware files. • The CDD‐880 is connected to a user‐supplied Windows‐based PC as follows: • o The PC serial port is connected to the CDD‐880 rear panel ‘CONSOLE’ port using a user‐supplied serial cable.
CDD-880 Multi Receiver Router Serial-based Remote Product Management Revision 1 MN-CDD880 Figure 6-1. CDD-880 Serial Interface Example CDD‐880 Serial Remote Product Management is available through the EIA‐232 operational interface, where the ‘Controller’ device (the user PC or an ASCII dumb terminal) is connected directly to the ‘Target’ device (the CDD‐880 Multi Receiver Router, via its DB‐9M ‘CONSOLE’ port).
CDD-880 Multi Receiver Router Serial-based Remote Product Management 6.2 Remote Commands and Queries Overview 6.2.1 Basic Protocol Revision 1 MN-CDD880 In an EIA‐232 configuration, the Controller device is connected directly to the Target device via a two wire‐plus‐ground connection. All data is transmitted in framed packets as asynchronous serial characters, suitable for transmission and reception to the Controller using a universal asynchronous receiver/transmitter (UART).
CDD-880 Multi Receiver Router Serial-based Remote Product Management Revision 1 MN-CDD880 Controller-to-Target (Issued Command or Query) Start of Packet Target Address Address Delimiter < ASCII code 60 0000 (default) / ASCII code 47 (1 character) (4 characters) (1 character) Packet Example: Instruction Code Code Qualifier Optional Arguments = or ? ASCII codes 61 or 63 (3 characters) (1 character) End of Packet Carriage Return ASCII code 13 (n characters) (1 character) Optional Arguments
CDD-880 Multi Receiver Router Serial-based Remote Product Management 6.2.2.2 Revision 1 MN-CDD880 Target Address In EIA‐232 applications, this value is set to 0000. The Target Address designates the packet destination. The Controller does not have its own address. After the Controller sends a packet with the designated Target Address, the Target responds to the Controller, using this same address, to indicate the source of the packet. 6.2.2.
CDD-880 Multi Receiver Router Serial-based Remote Product Management 6.2.2.5 Revision 1 MN-CDD880 Instruction Code Qualifier This is a single character that further qualifies the preceding instruction code. Code Qualifiers obey the following rules: From Controller‐to‐Target, the only permitted characters are: Character Definition = (ASCII code 61) This character is used as the Assignment Operator (AO).
CDD-880 Multi Receiver Router Serial-based Remote Product Management Revision 1 MN-CDD880 Character Definition ! (ASCII code 33) If the Controller sends an instruction code that the Target does not recognize, the Target responds by echoing the invalid instruction, followed by ! Example: CMD! 6.2.2.
CDD-880 Multi Receiver Router Serial-based Remote Product Management 6.3 Revision 1 MN-CDD880 Remote Commands and Queries The Serial Command Line interface (CLI) (the Controller), shown previously in , is used to issue remote commands and queries to the CDD‐880 (the Target). From the CLI command prompt CDD‐880> type in the command or query packet, using the format explained previously, for transmission to the CDD‐880.
CDD-880 Multi Receiver Router Serial-based Remote Product Management Revision 1 MN-CDD880 These Instruction Codes are explained in complete detail in the tables that follow. Note that the Target‐to‐Controller Instruction Code Qualifiers, described earlier, that appear in the “Response to Command” column carry the following meanings: = ? * # ! Parameter Type Default Passwords GE Address Message OK. Received OK, but invalid arguments were found. Message OK, but not permitted in current mode.

Appendix B. FEC (FORWARD ERROR CORRECTION) B.1 Introduction The FEC (Forward Error Correction) method used by the CDD‐880 Multi Receiver Router is a completely new family of short‐block Low Density Parity Check (LDPC) codes with very low ® latency called VersaFEC . VersaFEC is ideal for lower data rates that demand the shortest possible latency. It is a patent pending technology wholly owned and developed by Comtech EF Data and CEFD sister division Comtech AHA Corp.
