9.2.4 Multiple Beam Configuration
Multiple beam configuration can be used for Mobile VSATs, when they switch between different
satellites and transponders.
It is also a useful feature when the Hub operator is changing the forward link frequency or symbol rate.
Then the operator can configure both the current and the new Forward link on the VSATs. When the old
Forward link is removed, the VSAT will start to search for the second one, and lock to it, if available. The
VSAT will start tuning on the forward link configuration with highest priority (highest being 0 and lowest
being 9). When it is able to lock to a forward link, it will use this configuration, and start looking for
DVB-RCS tables distributed on the link. Up to 10 different forward link configurations can be configured
in the VSAT.
