Thanks Dave.
There is no problem is assigning a single link to the min active IMA links.
This will indeed allow you to utilize one link per IMA group. But that is
not the problem.
If the carrier doesn't support IMA (i.e. terminating the circuit to a T1
card and not a cell relay card with IMA support), all you will see is:
status is up while the line protocol is down.
That's why you will need to use pass through mode.

Thanks
