Brian, Thank you very much for the answer. BFGB> Igor, BFGB> First, can you point to somewhere in the world where TUP is still used?

But as it's similar to TUP in Routing Label structure I mentioned TUP in the question ( it's more well-known I think ). And IUP is used in the UK :) BFGB> Then, move the 4 bits of the CIC that normally overlap into the SLS BFGB> field of the SS7 routing label into the SLS field in the Protocol Data BFGB> parameter of M3UA and leave the other 8 bits of the CIC in the User BFGB> Protocol Data field of M3UA, just as is done in SS7 between the routing BFGB> label and the SIF.
