- 6.5.3 DTAM capability procedure
- 6.5.3.1DTAM Capability Procedure mapped onto Presentation Service (Normal Mode)
- This procedure is driven by the following events:
- a) a D-CAPABILITY request primitive from the requestor;
- b) a DCPQ APDU as User Data on a P-CAPAB-DATA indication primitive;
- c) a D-CAPABILITY response primitive from the responder; and
- d) a P-CAPAB-DATA confirm primitive (that may contain a DCPR APDU).
- 6.5.3.1.1D-CAPABILITY request primitive
- 6.5.3.1.1.1The requesting DTAM-PM forms a DCPQ APDU from parameter values of the D-CAPABILITY request primitive. It
- issues a P-CAPAB-DATA request primitive. The User Data parameter of the P-CAPAB-DATA request primitive contains the
- DCPQ APDU.
- 6.5.3.1.1.2The requesting DTAM-PM waits for a primitive from the Presentation service-provider, and does not accept any
- other primitive from the requestor other than a D-U-ABORT request primitive.
- 6.5.3.1.2DCPQ APDU
- 6.5.3.1.2.1The responding DTAM-PM receives a DCPQ APDU from its peer as User Data on a P-CAPAB-DATA indication
- primitive.
- 6.5.3.1.2.2In order that the DCPQ APDU may always be acceptable to the responding DTAM-PM, it issues a D-CAPABILITY
- indication primitive to the responder. The D-CAPABILITY indication primitive parameters are derived from the DCPQ APDU.
- The DTAM-PM waits for a D-CAPABILITY response primitive from the responder and does not accept any other primitives
- from the responder except for the D-U-ABORT request primitive.
- 6.5.3.1.3D-CAPABILITY response primitive
- 6.5.3.1.3.1When the DTAM-PM receives the D-CAPABILITY response primitive, the Result parameter specifies whether the
- responder has accepted or rejected the DTAM capability requested. The DTAM-PM forms a DCPR APDU using the D-
- CAPABILITY response primitive parameters. The DCPR APDU is sent as the User Data parameter on the P-CAPAB-DATA
- response primitive.
- 6.5.3.1.3.2If the responder accepted the DTAM capability request, the Capability Result field of the outgoing DCPR APDU
- also specifies the appropriate acceptance value. The DTAM capability is negotiated.
- 6.5.3.1.3.3If the responder rejected the DTAM capability request, the Result field of the outgoing DCPR APDU contains the
- appropriate rejection value. The DTAM capability is not established.
- 6.5.3.1.4P-CAPAB-DATA confirm primitive
- 6.5.3.1.4.1The requesting DTAM-PM receives a P-CAPAB-DATA confirm primitive. The following situations are possible:
- a) the DTAM capability has been accepted; or
- b) the responder has rejected the DTAM capability requested by the requestor.
- 6.5.3.1.4.2If the DTAM capability was accepted, the Capability Result field of the DCPR APDU specifies the appropriate
- acceptance value. The requesting DTAM-PM issues a D-CAPABILITY confirm primitive to the requestor based on parameters
- from the DCPR APDU. The D-CAPABILITY confirm primitive Capability Result Parameter specifies the appropriate acceptance
- value. The DTAM capability is negotiated.
- 6.5.3.1.4.3If the DTAM capability was rejected by the responder, the Capability Result field of the DCPR APDU on the P-
- CAPAB-DATA confirm primitive indicates the reason for rejection. The requesting DTAM-PM issues a D-CAPABILITY confirm
- primitive to the requestor based on parameters from the DCPR APDU. The D-CAPABILITY confirm primitive Capability Result
- parameter contains the appropriate rejection value. The DTAM capability is not established.
- 6.5.3.2DTAM capability procedure mapped onto session service (transparent mode)
- This procedure is driven by the following events:
- a) a D-CAPABILITY request primitive from the requestor;
-
-
-
-
-
-
-
-
-
-
- Fascicle VII.7 - Rec. T.433 1
-
-
-
- b) a DCPQ APDU as User Data on an S-CAPAB-DATA indication primitive;
- c) a D-CAPABILITY response primitive from the responder; and
- d) an S-CAPAB-DATA confirm primitive (that may contain a DCPR APDU).
-
- 6.5.3.2.1D-CAPABILITY request primitive
- 6.5.3.2.1.1The requesting DTAM-PM forms a DCPQ APDU from parameter values of the D-CAPABILITY request primitive,
- and issues an S-CAPAB DATA request primitive. The User Data parameter of the S-CAPAB DATA request primitive
- contains the DCPQ APDU.
- 6.5.3.2.1.2The requesting DTAM-PM waits for a primitive from the Session service-provider, and does not accept any other
-
- primitive from the requestor other than a D-U-ABORT request primitive.
-
- 6.5.3.2.2DCPQ APDU
- 6.5.3.2.2.1The responding DTAM-PM receives a DCPQ APDU from its peer as User Data on an S-CAPAB DATA indication
- primitive.
- 6.5.3.2.2.2In order that the S-CAPAB DATA indication primitive and its DCPQ APDU may always be acceptable to the
- responding DTAM-PM, it issues a D-CAPABILITY indication primitive to the responder. The D-CAPABILITY indication
- primitive parameters are derived from the DCPQ APDU. The DTAM-PM waits for a D-CAPABILITY response primitive from
- the responder and does not accept any other primitives from the responder except for the D-ABORT request primitive.
-
- 6.5.3.2.3D-CAPABILITY response primitive
- 6.5.3.2.3.1When the DTAM-PM receives the D-CAPABILITY response primitive, the parameters specified in its response
- primitive contain the Application Capabilities available at the responder. There is no way to issue the result of the capability
- negotiation explicitly. The DTAM-PM forms a DCPR APDU using the D-CAPABILITY response primitive parameters, and the
- DCPR APDU is sent as the User Data parameter on the S-CAPAB DATA response primitive.
- 6.5.3.2.3.2In this way, the DTAM capability is negotiated by exchanging the Application Capabilities parameters available at
-
- the responder.
-
- 6.5.3.2.4S-CAPAB DATA confirm primitive
- 6.5.3.2.4.1The requesting DTAM-PM receives an S-CAPAB DATA confirm primitive. The DTAM capability is always negotiated
- by exchanging the Application Capabilities parameters.
- 6.5.3.2.4.2If the DTAM capability was accepted, the requesting DTAM-PM issues a D-CAPABILITY confirm primitive to the
- requestor based on parameters from the DCPR APDU. The final decision of DTAM capability used in the transmission of a
- document will be made by the requesting DTAM-PM.
-
- 6.5.4 Use of the DCPQ/DCPR APDU fields
- The DCPQ APDU and DCPR APDU fields are used as follows.
-
- 6.5.4.1Application capabilities
- This is the Application Capabilities parameter value from the D-CAPABILITY request/response primitives. It appears
- as the Application Capabilities parameter value of the D-CAPABILITY indication/confirm primitives respectively. This parameter
- consists of the following sub-parameters.
-
- 6.5.4.1.1Document application profile
- The value of this parameter is either an Octet String or ASN.1 object identifiers. The Octet String designates the
- document application profile in line with the Recommendation T.73 (Document Application Profile - T.73). the ASN.1 object
- identifier must conform to the rules specified in ISO 8824 and designate an application profile defined in accordance with the
- rules specified in Recommendation T.411 (Document Application Profiles).
- 6.5.4.1.2Document architecture class
- The value of this parameter is "formatted".
-
- 6.5.4.1.3Non basic document characteristics
- The value of this parameter is any combination of Non Basic Document Characteristics defined in Recommendation
- T.414.
-
-
-
- 2 Fascicle VII.7 - Rec. T.433
-
- 6.5.4.1.4Non basic structural characteristics
-
- The value of this parameter is any combination of Non Basic Structural Characteristics defined in Recommendation
- T.414.
-
- 6.5.4.1.5Operational application profile
-
- The detailed specification of Operational Application Profile is for further study.
-
- 6.5.4.1.6Storage capacity
-
- See 6.2.4.8.
-
- 6.5.4.2Capability result
-
- If the DCPQ APDU was rejected by the responder, this field is supplied by the responder and is the Capability
- Result parameter from the D-CAPABILITY response primitive. In this situation, it appears as the Capability Result parameter
- on the D-CAPABILITY confirm primitive. This field can take one of the following:
- - confirmation that all the requested capabilities are available at the DTAM responder;
- - a list of the requested capabilities that are available at the DTAM responder;
- - a complete list of non-basic receiving capabilities;
- - an indication that no extended capabilities are available in the DTAM responder, or that none of the
- capabilities requested by the requestor are available.
- 6.5.4.3User information
- This is the User Information parameter from the D-CAPABILITY request and response primitive. It appears as the
- User Information parameter of the D-CAPABILITY indication and confirm primitive, if issued.
- 6.6 Document bulk transfer
- 6.6.1 Purpose
- 6.6.1.1The document bulk transfer is used to convey the document which contains ODA and Operational Structure to the
- remote DTAM user. The requestor who requests the remote Document bulk transfer should have a data taken in an
- appropriate manner. It supports the D-TRANSFER services.
- 6.6.1.2In this situation, either the Reliable Transfer Mode 1 or Mode 2 may be selected by the negotiation of functional
- units in the association establishment phase.
- 6.6.1.3If the reliable transfer functional unit is not selected, the RTSE service will be used. The use of RTSE is for further
- study.
- 6.6.1.4The Document Bulk Transfer is composed of two different sets of procedures depending on the Reliable Transfer
- Mode.
- 1) Reliable transfer mode 1
- a) Transfer Procedure for transmission of a complete document;
- b) Transfer-user-resume Procedure for retransmission of a partial document for resuming purposes. This
- procedure is controlled by the DTAM user;
- c) Transfer-interrupt Procedure to interrupt the transmission of a document in case of error;
- d) Transfer-discard Procedure to interrupt the transmission of a document in case of error and indicate that the
- part of the document already transmitted has to be deleted.
- In Reliable Transfer Mode 1, the Transfer-interrupt and the Transfer-discard Procedures result in a D-TRANSFER
- indication/confirmation to the DTAM user to indicate the failure of the transfer. The user is then responsible for initiating a
- new transfer (complete or partial document).
- Figures A-1/T.433 and A-2/T.433 illustrate the basic protocol sequences for the Reliable Transfer Mode 1.
-
-
-
-
-
-
- Fascicle VII.7 - Rec. T.433 3
-
-
-
- 2) Reliable transfer mode 2
-
- a) Transfer Procedure (see above, Reliable Transfer, Mode 1);
-
- b) Transfer-resume Procedure for retransmission of a partial document. This procedure is completely controlled
- by the DTAM-PM;
-
- c) Transfer-interrupt Procedure (see above Reliable Transfer, Mode 1);
-
- d) Transfer-discard Procedure (see above Reliable Transfer, Mode 1);
-
- e) Association-recovery Procedure (for further study).
-
-
- In Reliable Transfer Mode 2, following the Transfer-interrupt and Transfer-discard Procedures, the DTAM-PM
- initiates a new Transfer Procedure or a Transfer-resume Procedure. Attempts to transfer or retransfer the document may not
- be performed by the DTAM-PM after the transfer time is out. The transfer time-out may result to discard the document and to
- abort the procedure.
-
- Figures A-3/T.433 and A-4/T.433 illustrate the basic protocol sequences for the Reliable Transfer Mode 2.
-
- In the Transparent Mode under Session Service environment, only Reliable Transfer Mode 1 is used.
-
- In the Normal Mode under the OSI environment, both Reliable Transfer Modes 1 and 2 are available.
-
-
- 6.6.2 APDUs used
-
-
- 6.6.2.1No APDUs are used in this procedure. The Document Information corresponds to a D-TRANSFER request service
- primitive. There is no D-TRANSFER REQ APDU as such.
-
-
- 6.6.2.2Each Document Information, conveyed in a D-TRANSFER request, constitutes an Activity. For each application
- association, at most one Activity or one interrupted Activity awaiting resumption may exist at any one time.
-
-
- 6.6.2.3The Document Information, which consists of one or more interchange-data-elements as defined in 9.6.1.1 of
- Recommendation T.432, is segmented and reassembled into/from one or more segments. Each segment consists of one or
- more groups of interchange-data-elements and is transferred by the Presentation/Session data transfer services.
-
-
- 6.6.2.4A Document Information is transferred as a single User Data of the Presentation/Session data transfer services if
- checkpointing is not used within the Document Information, otherwise, the Document Information is transferred as a series of
- Presentation/Session data transfer services primitives. The concatenation of the user-data values of Presentation/Session data
- transfer services is Document Information. An example of document segmenting mechanism is given in Figure 2/T.433.

- 6.6.3 Transfer procedure
- This procedure is used to transfer a complete document.
- 6.6.3.1Transfer procedure mapped onto presentation service (normal mode)
- This procedure is driven by the following events:
- a) a D-TRANSFER request primitive from the requestor (sender of document);
- b) a P-ACTIVITY-START indication primitive, followed by one or more interchange-data- elements as user-data
- of P-DATA indication primitives each, except the last, followed by a P-MINOR-SYNCHRONZE indication
- primitive;
- c) a P-MINOR-SYNCHRONIZE confirm primitive;
- d) a P-ACTIVITY-END indication primitive;
- e) a P-ACTIVITY-END confirm primitive;
- f) a Transfer Time-out.
- Note - In the case of multiple documents transmission within one association, the above procedure will be applied
- repeatedly.
- 6.6.3.1.1D-TRANSFER request primitive
- 6.6.3.1.1.1If the requesting DTAM-PM possesses the Data Token and receives a D-TRANSFER request from the requestor,
- Document Information in the D-TRANSFER request primitive, which has an abstract form, is segmented by the group
- (segment) of interchange-data-elements. The segmenting unit (e.g. page, block) depends upon the characteristics of the
- DTAM-PM. The segmented abstract form is then transformed into the User Data in P-DATA.

-
-
-
- 6.6.3.1.1.2The parameter "Document Information Type" contained in the D-TRANSFER request should indicate "transfer of a
- document from its beginning", and the requesting DTAM-PM issues a P-ACTIVITY-START request primitive and may
- start transmitting the first segment of interchange-data- elements in a P-DATA request primitive immediately after the P-
- ACTIVITY-START request primitive is issued, since the P-ACTIVITY-START service is not a confirmed service.
-
- 6.6.3.1.1.3If the segment of interchange-data-elements transferred is not the last in a series of those segments, the
- requesting DTAM-PM inserts a checkpoint by issuing a P-MINOR-SYNCHRONIZE request primitive. The requesting DTAM-PM
- uses only the "explicit confirmation expected" type of minor synchronization. The requesting DTAM-PM may issue further P-
- DATA request primitives and P-MINOR- SYNCHRONIZE request primitives unless the agreed Window-size has been reached.
-
- 6.6.3.1.1.4P-Minor-Synchronization Points shall be located at the end of each segment of interchange-data-elements.
- Additional Minor Synchronization Point can be requested depending on the evaluation of the storage capacity of the sink and
- the amount of data to be transmitted. This additional Minor Synchronization Point shall only be located at the end of any
- interchange-data- elements and not within the element.
-
- 6.6.3.1.1.5If the segment of interchange-data-elements is the only one, or the last in a series of segments of interchange-
- data-elements, the requesting DTAM-PM issues a P-ACTIVITY-END request primitive. All data transfer must take place within
- an activity.
-
- 6.6.3.1.2P-ACTIVITY-START indication primitive, P-DATA PDUs, and P-MINOR-SYNCHRONIZE indication primitives
-
- 6.6.3.1.2.1The responding DTAM-PM receives a P-ACTIVITY-START indication primitive, indicating the start of transfer of
- Document Information. The responding DTAM-PM receives a P-MINOR-SYNCHRONIZE indication primitive. If the responding
- DTAM-PM has secured the segment of interchange-data-elements, it issues a P-MINOR-SYNCHRONIZE response primitive.
-
- 6.6.3.1.3P-MINOR-SYNCHRONIZE confirm primitive
-
- 6.6.3.1.3.1When the requesting DTAM-PM receives a P-MINOR-SYNCHRONIZE confirm primitive, it assumes that the
- responding DTAM-PM has secured the segments of interchange-data-elements up to that point.
-
- 6.6.3.1.3.2The requesting DTAM-PM may issue further P-DATA request primitives and P-MINOR- SYNCHRONIZE request
- primitives unless the agreed Window-size has been reached. The window is advanced when a P-MINOR-SYNCHRONIZE
- confirm primitive is received by the requesting DTAM-PM.
-
- 6.6.3.1.3.3When a complete Document Information has been transmitted, the requesting DTAM-PM issues a P-ACTIVITY-
- END request primitive.
-
- 6.6.3.1.4P-ACTIVITY-END indication primitive
-
- 6.6.3.1.4.1A P-ACTIVITY-END Indication primitive indicates to the responding DTAM-PM that a complete Document
- Information has been transferred.
-
- 6.6.3.1.4.2If the responding DTAM-PM has secured the complete Document Information, it issues a D-TRANSFER indication
- primitive to the responder, and issues a P-ACTIVITY-END response primitive.
-
- 6.6.3.1.4.3The responding DTAM-PM records the Session-connection-identifier and the Activity Identifier of the last Document
- Information which it completely secured for association-recovery purposes.
- 6.6.3.1.5P-ACTIVITY-END confirm primitive
- 6.6.3.1.5.1An activity end is an implicit major synchronization point and once successfully confirmed by means of a P-
- ACTIVITY-END confirm primitive, it indicates to the requesting DTAM-PM that the Document Information has been secured by
- the responding DTAM-PM. The requesting DTAM-PM may then delete the transferred Document Information.
- 6.6.3.1.5.2When the requesting DTAM-PM receives the P-ACTIVITY-END confirm primitive, it issues a D-TRANSFER confirm
- primitive with a Result parameter value of "document-information-transferred" to the requestor.

- 6.6.3.1.6Transfer time-out (only for reliable transfer mode 2)
-
- 6.6.3.1.6.1If a Document Information has not been transferred within the time specified in the Transfer-time parameter of the
- D-TRANSFER request primitive (that is, the requesting DTAM-PM has not received the P-ACTIVITY-END confirm primitive),
- the requesting DTAM-PM performs the transfer-discard procedure (see 6.6.6) followed by the transfer-abort procedure (see
- 6.4.3.1.4).
-
- 6.6.3.1.6.2If during the transfer-discard procedure the requesting DTAM-PM does not receive a P-ACTIVITY-DISCARD confirm
- primitive within a (locally specified) reasonable time, the requesting DTAM-PM performs the transfer-abort procedure followed
- by the DTAM provider-abort procedure.
-
- 6.6.3.2Transfer procedure mapped onto session service (transparent mode)
- This procedure is driven by the following events:
- a) a D-TRANSFER request primitive from the requestor (sender of document);
- b) an S-ACTIVITY-START indication primitive, followed by one or more interchange-data- elements as user-
- data of S-DATA indication primitives each, except the last, followed by an S-MINOR-SYNCHRONIZE
- indication primitive;
- c) an S-MINOR-SYNCHRONIZE confirm primitive;
- d) an S-ACTIVITY-END indication primitive;
- e) an S-ACTIVITY-END confirm primitive;
- Note - In the case of multiple document transmission within one association, the above procedure will be applied
- repeatedly.
-
- 6.6.3.2.1D-TRANSFER request primitive
- 6.6.3.2.1.1If the requesting DTAM-PM possesses the Data Token and receives a D-TRANSFER request from the requestor,
- Document Information in the D-TRANSFER request primitive which has an abstract form is segmented by the group
- (segment) of interchange-data-elements. The segmenting unit (e.g. page, block) depends upon the characteristics of the
- DTAM-PM. The segmented abstract form is then transformed into the User Data in S-DATA.
- 6.6.3.2.1.2The parameter "Document Information Type" contained in the D-TRANSFER request should indicate the "transfer of
- a document from its beginning", and the requesting DTAM-PM issues an S-ACTIVITY-START request primitive and may start
- transmitting the first segment of interchange-data- elements in an S-DATA request primitive immediately after the S-
- ACTIVITY-START request primitive is issued, since the S-ACTIVITY-START service is not a confirmed service. All data
- transfer should take place within an activity.
- 6.6.3.2.1.3If the segment of interchange-data-elements transferred is not the last in a series of those segments, the
- requesting DTAM-PM inserts a checkpoint by issuing an S-MINOR-SYNCHRONIZE request primitive. The requesting DTAM-
- PM uses only the "explicit confirmation expected" type of minor synchronization. The requesting DTAM-PM may issue further
- S-DATA request primitives and S-MINOR- SYNCHRONIZE request primitives unless the agreed Window-size has been
- reached.
- 6.6.3.2.1.4S-Minor-Synchronization Points shall be located at the end of each segment of interchange-data-elements.
- Additional Minor Synchronization Points can be requested depending on the evaluation of the storage capacity of the sink
- and the amount of data to be transmitted. This additional Minor Synchronization Points shall only be located at the end of
- any interchange-data- elements and not within the element.
- 6.6.3.2.1.5If the segment of interchange-data-elements is the only one, or the last in a series of segments of interchange-
- data-elements, the requesting DTAM-PM issues an S-ACTIVITY-END request primitive. All data transfer must take place
- within an activity.
- 6.6.3.2.2S-ACTIVITY-START indication primitive, S-DATA PDUs, and S-MINOR-SYNCHRONIZE indication primitives
- 6.6.3.2.2.1The responding DTAM-PM receives an S-ACTIVITY-START indication primitive, indicating the start of transfer of
- Document Information. The responding DTAM-PM receives an S-MINOR-SYNCHRONIZE indication primitive. If the responding
- DTAM-PM has secured the segment of interchange-data-elements, it issues an S-MINOR-SYNCHRONIZE response primitive.

-
- 6.6.3.2.4.1An S-ACTIVITY-END Indication primitive indicates to the responding DTAM-PM that a complete Document
- Information has been transferred.
-
- 6.6.3.2.4.2If the responding DTAM-PM has secured the complete Document Information, it issues a D-TRANSFER indication
- primitive to the responder, and issues an S-ACTIVITY-END response primitive.
-
- 4.6.3.2.5S-ACTIVITY-END confirm primitive
-
- 6.6.3.2.5.1An activity end is an implicit major synchronization point and once successfully confirmed by means of an S-

- This procedure is driven by the following events:
- a) a D-TRANSFER request primitive from the requestor (sender of document);

- c) a P-MINOR-SYNCHRONIZE confirm primitive;
- d) a P-ACTIVITY-END indication primitive;
- e) a P-ACTIVITY-END confirm primitive.
- 6.6.4.1.1D-TRANSFER request primitive
- 6.6.4.1.1.1If the requesting DTAM-PM possesses the Data Token and receives a D-TRANSFER request from the requestor,
- Document Information in the D-TRANSFER request primitive, which has an abstract form, is segmented by the group
- (segment) of interchange-data-elements. The segmenting unit (e.g. page, block) depends upon the characteristics of the
- DTAM-PM. The segmented abstract form is then transformed into the User Data in P-DATA.
- 6.6.4.1.1.2The parameter "Document Information Type" contained in the D-TRANSFER request should indicate "transfer of a
- document from a synchronization point", and the requesting DTAM-PM issues a P-ACTIVITY-RESUME request primitive and
- may continue the transfer procedure by issuing a P-DATA request primitive for the segment of interchange-data-elements
- following the last confirmed checkpoint. The checkpoint information is from the parameter "Synchronization Point" in the D-
- TRANSFER request primitive.
- 6.6.4.1.1.3Another detailed procedure is followed by the 6.6.3.1.1.3, 6.6.3.1.1.4 and 6.6.3.1.1.5.

- 6.6.4.2.1D-TRANSFER request primitive
- 6.6.4.2.1.1If the requesting DTAM-PM possesses the Data Token and receives a D-TRANSFER request from the requestor,
- Document Information in the D-TRANSFER request primitive, which has an abstract form, is segmented by the group
- (segment) of interchange-data-elements. The segmenting unit (e.g. page, block) depends upon the characteristics of the
- DTAM-PM. The segmented abstract form is then transformed into the User Data in P-DATA.
- 6.6.4.2.1.2The parameter "Document Information Type" contained in the D-TRANSFER request should indicate the "transfer of
- a document from a synchronization point", and the requesting DTAM-PM issues an S-ACTIVITY-RESUME request primitive
- and may continue the transfer procedure by issuing a S-DATA request primitive for the segment of interchange-data-
- elements following the last confirmed checkpoint. The checkpoint information is from the parameter "Synchronization Point" in
- the D-TRANSFER request primitive.
- 6.6.4.2.1.3Another detailed procedure is followed by the 6.6.3.2.1.3, 6.6.3.2.1.4 and 6.6.3.2.1.5.
- 6.6.4.2.2S-ACTIVITY-RESUME indication primitive, S-DATA PDUs, and S-MINOR-SYNCHRONIZE indication primitives
- 6.6.4.2.2.1The responding DTAM-PM receives an S-ACTIVITY-RESUME indication primitive, indicating the start of transfer of
- Document Information. The responding DTAM-PM receives an S-MINOR- SYNCHRONIZE indication primitive. If the
- responding DTAM-PM has secured the segment of interchange- data-elements, it issues an S-MINOR-SYNCHRONIZE
- response primitive.
- 6.6.4.2.3S-MINOR-SYNCHRONIZE confirm primitive
- 6.6.4.2.3.1The detailed procedure is followed by the 6.6.3.2.3.1, 6.6.3.2.3.2 and 6.6.3.2.3.3.
- 6.6.4.2.4S-ACTIVITY-END indication primitive
- 6.6.4.2.4.1The detailed procedure is followed by the 6.6.3.2.4.1 and 6.6.3.2.4.2.
- 6.6.4.2.5S-ACTIVITY-END confirm primitive
- 6.6.4.2.5.1The detailed procedure is followed by the 6.6.3.2.5.1 and 6.6.3.2.5.2.
