Instead of one large routing switcher, there are often 2 separate routing switchers. One handling 4:2:2,
and the other 4fsc. The output of the 4:2:2 would cascade through the 4:2:2 to 4fsc converters, and on to
the inputs of the 4fsc routing switcher. The opposite configuration would be set up for going from 4fsc to
4:2:2.
What is done here is that groups of inputs are combined in a Source Name group, along with groups of
outputs known as Destination Name groups. Net (Path) Groups are then created, each one being a list of
routing switcher outs to routing switcher in’s to be used.
When a input in a source group is selected, or an output in a destination group, the routing switcher looks
at successive paths (their order as entered in each path group) until it finds an unused one.

Each Source, Destination, and Net group can have up to 4 entries in it.
There can be a total of 20 Source, and 20 Destination groups.
There can be up to 40 Net groups.
Each Source and Destination group are tied together by 1 Net group.
Up to 3 routing switchers, or 2 recursive paths into 1 routing switcher can be supported.
