Could you provide an example?

Are you supposed to use same linkset for both spans? I'm getting 
something like this when the linksets are the same:

MTP2 link up (SLC 0)
MTP2 link up (SLC 1)
--- SS7 Up ---
Resetting CICs 1 to 15
Resetting CICs 17 to 31
Resetting CICs 63 to 77
Resetting CICs 79 to 93

and this if they're different:
