This structure specifies the presentation indicator, numbering plan, and screen indicator of a party. This structure is referenced in supplementary service data structures.

The invoke field in this structure indicates whether this information is included or not, in cases where this information is optional. If invoke is ON, the information is present. If invoke is OFF, the information is not present.

The offset field in this structure is calculated from the beginning of this structure (the address of the invoke field).
