Appendix L. CDM-570L ODU
(BUC, LNB) OPERATION
L.1 Introduction
The CDM-570L and CDMR-570L Satellite Modems (referred to collectively as the CDM-570L)
may be used to fully configure, monitor, and control a Comtech EF Data ODU (Outdoor Unit).
‘ODU’ is the mnemonic for a BUC (Block Up Converter) or an LNB (Low-Noise Block Down
Converter).
ODU operation may be monitored and controlled via the following methods:
• By using ODU remote commands through Serial Remote or Telnet
• By using the keypad and display via the front panel of a CDM-570L Modem
• By using the CDM-570L Base Modem HTTP Interface
• By using the SNMP Interface with the CDM-570L BUC or LNB MIB
L.2 ODU Remote Control Address Setup
The ODU connected to a CDM-570L through FSK (Frequency Shift Keying) can be remotely
monitored and controlled by using ODU remote commands through Serial Remote or Telnet. The
address of the ODU is set up as follows:
• For local-end ODUs:
o Use Modem’s RC address + 1 for Standalone unit or Online unit in a 1:1 Redundancy
System
o Use Modem’s RC address + 2 for Offline unit in a 1:1 Redundancy System
• For distant-end ODUs in an EDMAC setup:
o Use EDMAC Slave Address (ESA) Range + 4 for Standalone unit or Online unit in a
1:1 Redundancy System
o Use EDMAC Slave Address (ESA) Range + 5 for Offline unit in a 1:1 Redundancy
