When enabled, the burst controller sets a flag in the burst map that indicates it is
not receiving acknowledgements from an enabled Remote. When the Remote
receives the burst map, it will see the flag and automatically increase power by

This feature is enabled by selecting the check box.
Enable Low Data Rate Fast Acquisition
Configurable on a Hub Burst Controller only.
Selecting this check box enables the Vipersat Burst Fast Acquisition Timing
(BFAT) feature that functions at low data rates (64 kbps to 256 kbps). This
feature allows for significantly faster acquisition times at these data rates, even
with higher noise, resulting in improved efficiency of the shared STDMA chan-
