CIC shouldn't be there, since that requires inappropriate knowledege
of other protocol layers. It is also impossible to implement ISUP
group messages with such a naive routing rule.

You should also have DPC,SSN,OPC

One includes the source address!

To route traffic from different systems to different applications!

For ISUP traffic this might let you split the load between different
systems - since the traffic for each relation (pointcode pair) is
completely separate.
