F-18 Appendix F: Redundant Backup
Moseley SL9003Q 602-12016 Revision G
Receiver
Figures F-10 and F-11 show a typical Starlink QAM (STL) Main/Standby with DSP/PCL as
backup configuration for the receiver end of the link. A TPT-2 is not required, as both of the
receivers are “ON” all the time. The antenna input is split to the two receivers with an RF power
divider.
Receiver Audio Switching – with Optimod Audio Processor
The Main and Standby audio outputs can be routed to the inputs of an Orban Optimod stereo
generator (with the AES/EBU input option) or similar device. Route the AES/EBU from the Main
receiver and the analog from the Standby receiver, and the Optimod will always default to the
AES/EBU input if the data is valid (i.e., the receiver audio data is locked).
