PS2, Line 68:   inout charstring, CallParameters, ASCI_Event;
As can be seen from the existing code, we tend to define strings as named 
constants and then send/match these constants rather than typing strings here 
and there. This is clearly better because this eliminates problems due to 
possible typos in strings.

```
COORD.send("CALL_READY");
...
COORD.receive("C[E]LL_READY");
```

So personally I really like the idea of using (valueless) enums and I vote for 
them.

The problem is that... There is no `enum2str()` in TTCN-3.

What I don't like in the current patch revision is that we end up having 
testsuite specific stuff in a common module: `ASCI_Event` in this case. IMO, 
it's cleaner if each testsuite (`MSC_Tests`, `MSC_Tests_Iu`, and the new 
`BSC_Tests_ASCI`) would define its own COORD port and the related enums/types 
internally. This may not apply to the `MSC_Tests_Iu`, because it's mostly 
re-using the test logic from `MSC_Tests`, but I don't see the need for the 
`MSC_Tests[_Iu]` to have access to ASCI specific port messages.
