Vipersat Cross Banding Solution
Figure A-2 illustrates a schematic representation of a cross banded satellite
network.
Figure A-2 A Cross Banded Satellite Network
The VMS does the following to allow a cross banded satellite network to be
included in its management and control functions:
• VMS adds a translation override frequency to the transponder object
which is used in place of the satellite’s normal translation frequency
• The VMS bandwidth allocation logic then:
• Selects demodulators first
• Builds a collection of frequency limits based on available transponders
• Selects modulators based on their intersecting limits
Note: The VMS cross band function has no effect on non-cross banded
configurations, and supports multiple transponders.
Figure A-3 shows a cross banded network configuration.
