I made a reply on "obg-club" only, and noticed just now that the
on RPC in MSCs runs on "mscnews". So I post it again:

There are no RPCs in Z.120. But RPCs in SDL are modelled, and
implemented in OG Simulator by mean of messages. For a remote procedure
"xxx", the messages exchanged are "rpc_xxx_call" (parameters identical
to the remote procedure parameters) and "rpc_xxx_reply" (the parameters
are the in/out parameters of the remote procedure).
You can view these messages in MSCs generated by OG Simulator 3.2. It
will be possible to give MSCs including these messages as input to OG
Simulator 4.0 comming soon, so you will have exactly what you want :-)
