10.3.3.3.3 ODU: FSK-control
Comtech EF Data ODUs (CSAT, KST, or
LPOD
), when connected to a CDM-625A through
Frequency Shift Keying (FSK), can be remotely monitored and controlled by using the CDM-625A
front panel, Web Server interface, or by using remote commands and queries through Serial or
Telnet Remote Product Management. In order to facilitate remote M&C, the ODU address is set
up as follows:
•
For Local-End ODUs:
o
Use the Modem’s RC A 1 for a Standalone Unit or the Online Unit in a 1:1
Redundancy System;
o
Use the Modem’s RC A 2 for the Offline Unit in a 1:1 Redundancy System.
•
For Distant-End ODUs in an EDMAC setup:
•
Chapter 8. SERIAL-BASED REMOTE PRODUCT MANAGEMENT
•
Appendix H. EDMAC CHANNEL
o
Use the EDMAC Slave Address (ESA) Range +4 for Standalone Unit or the Online Unit in a
1:1 Redundancy System;
o
Use the EDMAC Slave Address (ESA) Range +5 for the Offline Unit in a 1:1 Redundancy
System.
The appearance of the
ODU: FSK-control
screen adjusts automatically to the mode of operation:
70/140 MHz
or
L-Band
.
When the Tx frequency is 70/140 MHz
– Communication with a Comtech EF Data CSAT or KST
transceiver is achieved using a low-speed, half-duplex FSK link over the Rx IF port, with a carrier
frequency around 2.7 MHz.
With FSK communication
disabled
, the
ODU: FSK-control
screen appears as shown here:
ODU Control: FSK=Off (Off,On)
ODU Type: C/KST (C/KST, 2CSATS)
