Note that DSG tunnel groups are used for assigning a group of DSG tunnels to one or more DS cable interfaces. This also
allows the user to assign one or more DSG tunnel groups to a DS cable interface. A DSG tunnel must belong to a group in
order to be associated with a DS cable interface.
The DSG tunnel groups should be determined before starting advanced DSG configuration. However, DSG configuration is
significantly simplified when there is a maximum of one DSG tunnel per DSG tunnel group.
