Hi,

I have Iur and IuCS traffic in the same capture file, i.e. both run on
SSCOP, MTP3B, SCCP. On IuCS the layer above SCCP is RANAP, on Iur it is
RNSAP. I managed to decode the IuCS by making use of the USER DLT (set to
147 in my trace), and then set the Special Encapsulation to SSCOP and the
Payload to "mtp3". Is there another way?

What do I have to do to get the Iur frames decoded?

In may trace:
- Frame 1,2,3,4,11 are RANAP (IuCS)
- Frame 5,6,7,8,9,10 are RNSAP (Iur)

As you may know the RNSAP messages can get pretty long so that they don't
fit into one SCCP frame anymore. The SCCP layer gets segmented (as it is the
case in my trace with frame 7,8,9). Does Ehtereal do a reassembly of the
sgemented SCCP?

/Roger
