A "normal" digi would usually have wide-area coverage. A "fill-in" digi 
would provide a mechanism to access the wide-area digi from, say, a 
shadow area within the wide-area digi's coverage.

In old parlance a fill-in digi used the intuitive RELAY alias. Under the 
new, more channel efficient scheme, it would be WIDE1-1
.
A home station with a good path to a wide-area digi might use WIDE2-1 in 
the path. For a mobile, the path, typically, be WIDE1-1 WIDE2-1 to take 
advantage of any "fill-in " system that might exist.
