It should be 1 to 4 and 2 to 5, not 3. The pairs are 1-2 and 4-5.

That should have worked, as long as 1-1, 2-2, 4-4 and 5-5. Are you sure 
the signalling is correct? What did zttool say?

Yellow alert is remote alert, right? That would indicate that the path 
from the pbx to asterisk is ok, but not the path from asterisk to the pbx.

I think you have to start asterisk on the span to get the upper layers 
enabled.
