Its purpose is to specify an operational structure class suitable for videotex interworking as defined in configuration 1 of CCITT Recommendation F.300 and in Recommendation T.564. 2 Field of application This Recommendation defines an operational application profile, that is in conformance with DTAM (T.400 Series of Recommendations) and that allows operational structures to be interchanged for the purpose of an international videotex interworking. This operational application profile defines the features of the operational structure that can be interchanged. These features are depending on the document structures as specified in the document application profile (see Recommendation T.504). 1 Fascicle VII.7 - Rec. T.541 3 References - Rec.

T.541 2 5 Characteristics supported by this operational application profile 5.1 Overview For the purpose of videotex interworking operational structures are associated with a videotex document to provide an environment for interactive communication, necessary for a recipient to handle the userw's input data as intended by the originator. Therefore the purpose of this section is to specify the functional description of the features supported by this operational application profile. 5.2 Range of operational structures For the purpose of an international videotex interworking four operational structures are specified, one of each representing the "data entry structure", the "application control memory", the "administrative structure" and the "special terminal facilities structure" as defined in Recommenda- tion T.564. 5.3 Generic characteristics Not used. 5.4 Specific characteristics Each of the operational structures specified in this operational application profile only supports specific features of operational structures. 6 Definition of the operational application profile 6.1 Complexity level of operational structures For further study. 6.2 Operational profile level One operational profile has to be defined for every application using operational structures. This operational profile specifies: - Four operational structures are used; - Each of the operational structures only contains specific features. Details are for further study. 6.3 Specification of operational structures Four operational structures are specified by this operational application profile. 6.3.1 Data entry structure The data entry structure as defined in draft Recommendation T.564 is mapped onto one specific operational structure. No generic operational structure is present. The Data-Entry-SE is mapped to the specific operational root. The object identifier of the root of this operational structure has an assigned value of 11. The subordinates of Data-Entry-SE are: Data-Entry-Program-SE, Field-SE, Rules-SE, Prompt-SE, and Result-SE. Data-Entry-Program-SE is mapped to composite operational object. Field-SE, Rules-SE, Prompt-SE and Result-SE are mapped to basic operational objects. Field-SE, Prompt-SE and Result-SE may have associated operational elements. Subordinate to Data-Entry-Program-SE is Data-Entry-Subprogram-SE. Data-Entry-Subprogram-SE is mapped to basic operational object. For each of the SEs specified above, constraints are defined on the number of SEs which may exist at one time. These constraints are defined in Recommendation T.564. 3 Fascicle VII.7 - Rec. T.541 6.3.2 Application control memory structure The application control memory structure as defined in Recommendation T.564 is mapped onto one specific operational structure. No generic operational structure is present. The Application-Control-Memory-SE is mapped to the specific operational root. The object identifier of the root of this operational structure has an assigned value of 12. Subordinate to the Application-Control-Memory-SE is the Record-SE. The Record-SE is mapped to basic operational object. For each of the SEs specified above, constraints are defined on the number of SEs which may exist at one time. These constraints are defined in Recommendation T.564. 6.3.3 The administrative structure The administrative structure as defined in Recommendation T.564 is mapped onto one specific operational structure. No generic operational structure is present. The Administrative-Information-SE is mapped to the specific operational root. The object identifier of the root of this operational structure has an assigned value of 13. 6.3.4 Special terminal facilities structure The special terminal facilities structure as defined in Recommendation T.564 is mapped onto one specific operational structure. No generic operational structure is present. The Specific-Terminal-Facilities-SE is mapped to the specific operational root. The object identifier of the root of this operational structure has an assigned value of 14. Subordinate to the Special-Terminal-Facilities-SE is the Redefinition-Entity-SE. Redefinition- Entity-SE is mapped to basic operational object. For each of the SEs specified above, constraints are defined on the number of SEs which may exist at one time. These constraints are defined in Recommendation T.564. 6.4 Specification of attributes The attributes applicable to constituents of the operational structure are defined in the following tables, using the following notation: -- attribute not applicable m attribute is mandatory nm attribute is non-mandatory d attribute is defaultable From the attributes specified for operational structures in Annex A to this Recommendation, videotex interworking will not use the attributes operational object class and subordinates. The use of the attribute document fragment is for further study. 6.4.1 Attributes of the data entry structure Fascicle VII.7 - Rec.
