(This Annex forms an integral part of this Recommendation)
This Annex includes overview and detailed SDL diagrams which show Q.931 protocol control for circuits-switched basic calls. In the event of conflict between these diagrams and the text of clause 5, the text should be the prime source. Similarly, in the event of conflict between overview SDL and detailed SDL diagrams, the detailed SDL diagrams should be the prime source.
Figure A.1 shows key to Q.931 protocol control SDL diagrams for both user side and network side.
Figures A.2 and A.3 show overview and detailed protocol control SDL diagrams for the user side.
Figures A.5 and A.6 show overview and detailed protocol control SDL diagrams for network side. Only procedures for the point-to-point configuration are described in the network side SDL diagrams
Note - Network side SDL diagrams for the point-to-multipoint configuration are left for further study.
Figure A.4 shows detailed SDL diagrams for the global call reference to be applied to both user and network sides. Although Figure A.4 shows SDL diagrams in the user-side only, the same diagram scan be applied to the network side by just changing the direction of input and output symbols.
