|

*
|

* The RUA_Emulation.main() function processes RUA messages from the Iuh stack

* Outbound RUA connections are initiated by sending a FIXME primitive to the

* RUA_Emulation component.
|
||||
*
|
||||
* For each new inbound connection, the RuaOps.create_cb() is called. It can create
|
||||
* or resolve a TTCN-3 component, and returns a component reference to which that inbound
|
||||
* connection is routed/dispatched.
|
||||
*
|
||||
* If a pre-existing component wants to register to handle future inbound connection,
|
||||
* it can do so by registering an "expect" with the expected RANAP payload.
