Combined Redundant Return

In the combined redundant return configuration, two, three, or four RF returns are combined

onto a combined redundant return board. The combined redundant return board directs the

signals to two return transmitters located in lid optics slots 3 and 4. This board is located in

configuration location 2, as shown in Figure 3-24.

Figure 3-24 illustrates the combined redundant return configuration.
