• CDM-600L (CLM-9600L) with CRS-150 1:1 Data Switch
• SDM-300L3 with SMS-301 1:1 Data Switch
• Fully Automatic under control of supporting 1:1 switch.
• Manual under control of supporting 1:1 switch.
• Full bridging architecture when supported by CRS-150, or SMS-301
data switching and control, with configuration synchronization.
• Tx redundancy supports all BUC interface signals (RF, 10 MHz
reference, FSK communications, and power supply)
• Rx IF signal fed to both Online and Standby units. Rx switching
supports all LNB interface signals (RF, 10 MHz reference, and power
supply.)
Tx/Rx switching follows state of supporting data switching via control input
from data switch.
• Tx IF: Switched by RF relay (1.5 dB max loss, 40 dB min ON/OFF
isolation)
• Rx IF: Passive power splitting (7 dB max loss)
Switched by power relay (60VDC max, 4A max)
