B.4 Grouping Pattern Examples
For switching purposes, connectors can be grouped in two basic patterns of
virtual channels, spanning and sequential. Explanations and examples of each
follow.

Spanning Grouping Pattern

A spanning pattern is the most common method of grouping connectors for an
Epica Distribution Matrix. When this pattern is selected, all instances of a single
component in an aggregate signal are assigned to virtual channels that
correspond to connectors on different boards.
Example
In the Y/c system in Figure 22, the "Y" component is assigned to all of the
connectors on the first input board, and the "c" component is assigned to all of
the connectors on the second input board. The first connector on the "Y" board
and the first connector on the "c" board switch simultaneously, thereby routing
the "Y" and "c" signals together. The rest of the connectors for all of the Y/c
boards (input and output) in the system would be assigned in the same way. This
configuration routes 16 channels of Y/c per each pair of boards.
Figure 22: Grouping connectors in a spanning pattern
Note: Instead of alternating a "Y" and a "c" board, all of the "Y" input boards
could be installed adjacent to each other followed by all the "c" input boards.
The output boards would be installed in the same pattern.
