5i' ANNEX A (to Recommendation Q.931) User side and network side SDL diagrams This Annex includes overview and detailed SDL diagrams which show Q.931 protocol control for circuit-switched basic calls. In the event of conflict between these diagrams and the text of S 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/Q.931 shows key to Q.931 protocol control SDL diagrams for both user side and network side. Note - The same name as is specified in Recommendation Q.699 is used for each primitive to be exchanged between Q.931 protocol control and call control, whenever it is possible. Alignment of primitive names with those specified as OSI terminology may be required. Figure A-2/Q.931 and A-3/Q.931 show overview and detailed pro- tocol control SDL diagrams for the user side. Figure A-5/Q.931 and A-6/Q.931 show overview and detailed pro- tocol control SDL diagrams for the 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/Q.931 shows detailed SDL diagrams for the global call reference to be applied to both user and network sides. Although Figure A-4/Q.931 shows SDL diagrams in the user-side only, the same diagrams can be applied to the network side by just chang- ing the direction of input and output symbols.
