-
- T.400 Series of Recommendations define the open document architecture (T.410 Series) and the DTAM services
- and protocols (T.430 Series) for the purpose of the document transfer and manipulation. In order to apply T.400 Series to
- various telematic services, it is necessary to specify the DTAM application profile for each service that consists of a document
- application profile and a communca- tion application profile.
- According to this requirement, T.500 Series of Recommendations define the document application profiles and
- T.520 Series of Recommendations define the communication application profiles.
- Recommendation T.522 is one of a set of T.520 Series of Recommendations to define the communi- cation
- application profile for the document bulk transfer using X.200 environment.
-
-
- 1 Scope and field of application
-
-
- This Recommendation defines the communication application profile for the document bulk transfer in terms of:
- a) DTAM functional units used;
- b) DTAM service primitives and parameters used.

- 5 Definitions of communication application profile BT1
-
-
- 5.1 Overview of BT1
- This Recommendation defines functional units and communication support function in accordance with
-
- Recommendation T.431.
-
- 5.2 DTAM functional units
- The following functional units defined in Recommendation T.432 are used for BT1:
- - association use control (kernel);
- - capability;
- - document bulk transfer;
- - token control;
- - exception report;
- - reliable transfer mode 2.
-
- 5.3 DTAM service primitives and parameters
- General DTAM service definition and parameters are defined in Recommendation T.432. This section specifies the
-
- parameters of DTAM service of BT1.
-
- 5.3.1 D-INITIATE service parameters
- The following parameters of this service are used as follows:
- - telematic requirements;
- - application capabilities;
- - result.
- The parameter "transparent mode" is not used.
- Table 1-A/T.522 lists the D-INITIATE service parameters.
- 1) Telematic requirements
- The following functional units defined in Recommendation T.432 are used for BT1 as mandatory functional
- units:
- - association control (kernel);
- - document bulk transfer;
- - token control;
- - exception report;
-
-
-
- 2 Fascicle VII.7 - Rec. T.522

- 2) Application capabilities
- This "application capabilities" is defined in Recommendation T.432 and the following sub- parameters are
- used:
- a) document application profile
- This parameter indicates the document application profile being used. Its value is specified in
- Recommendations that define terminal characteristics for particular telematic services.
- b) non-basic document characteristics
- This is the "non-basic document characteristics" defined in Recommendation T.432.
- c) non-basic structure characteristics
- This is the "non-basic structure characterisitcs" defined in Recommendation T.432.
- 3) Result
- This field can take all the values defined in Recommendation T.432.
