Igor,

First, can you point to somewhere in the world where TUP is still used?

Next, can you indicate who in that part of the world will be running TUP
over M3UA?

Then, move the 4 bits of the CIC that normally overlap into the SLS
field of the SS7 routing label into the SLS field in the Protocol Data
parameter of M3UA and leave the other 8 bits of the CIC in the User
Protocol Data field of M3UA, just as is done in SS7 between the routing
label and the SIF.
