Not all national networks support multiple congestion levels.

Yes.

If the network supports multiple congestion levels and does not provide a
congestion indication then it does not follow the RFC and does not provide
sufficient information to generate a national MTP-STATUS indication primitive.

IMO local management the ASP should be informed of this misconfiguration at
the SG as local MTP applications will not behave correctly with regard to
SS7 signalling network congestion.
