FLex 6600 "SCU" vs "Independant" receivers.

As I understand, the Flex 6700 has two SCUs from which you spawn slice receivers tied to each SCU.   The Flex 6600 spec sheet shows an "independent" receiver number.  The number of SCUs seem to determine whether you can do full duplex with 2M/440 down convertors.   I am trying to work out the number of SCUs on the Flex 6600, and whether full duplex satellite work is possible when fitted with downconvertors.   Can anyone shed light on the number of SCU for the Flex 6600?  Thanks

The specs for the 6600 are exactly the same as the 6700, except for the number of slices 4 vs 8. The 6600 has two independent SCU's and two independent Transverter ports, and is Full Duplex.
