Introducing the DSR-4550
Disaster Recovery
The DSR-4550 performs automatic disaster recovery of lost L-band signal without
operator intervention based on settings and definitions provided by the uplink equipment.
The DSR 4550 does the following in disaster recover mode:
• Mutes all outputs
• Maintains the current Low Noise Block (LNB) Converter offset
• Attempts to reacquire the lost L-band signal until the transponder-search entry delay
time period has elapsed (default value is 30 seconds).
Note: Transponder search entry delay time is set up by the uplink equipment.
• Automatically terminates disaster recovery when the lost signal is acquired.
