The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Teleco

4、mmunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in

5、WTSC Resolution No. 1 (Helsinki, March 1-12, 1993). Amendment 1 to ITU-T Recommendation T.433, was prepared by ITU-T Study Group 8 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 1 lth of August 1995.

12、transfer of Group 4 Telefax documents as the DTAM transparent mode and of arbitrary documents and binary files in the DTAM normal mode. Amendment 1 provides for the transfer of binary files (based upon Recommendation T.434), and other formats, such as DTM, JPEG, EDIFACT and also Colour facsimile doc

13、uments in the DTAM transparent mode. This amendment mainly concentrates on the amendments for the association establishment, where the relevant formats need to be recognized, and on the transfer phase, where segmenting must be extended to information that is not structured page by page. iv Recommend

15、pport colour and file transfer extension for G4 facsimile application. 2 Modification of Recommendation T.433 2.1 The second paragraph of 5.3.2 in Recommendation T.433 should be replaced by the following new paragraph 5.3.2 Functions of DTAM service-provider 2) DTAM capability The DTAM capability is

16、 defined by sets of parameters in order to specify the communication features: ODA application capabilities a) document application profile; b) operational application profile; c) non-basic document characteristics; d) non-basic structural characteristics; and e) additional document characteristics,

17、 etc. File transfer capabilities a) BFT capabilities; b) Transparent Data Capabilities; c) DTM capabilities; d) EDIFACT capabilities. Private capabilities 2.2 6.2.4.3.1.6 Additional document characteristics The value of this parameter is any combination of additional document Characteristics defined

18、 in Recommendation T.414. The following new subclause should be added after 6.2.4.3.1.5 in Recommendation T.433 Recommendation T.433 / Amd.1 (08/95) 1 STD-ITU-T RECMN T.433 AID 1-ENGL 1775 D 48b2571 Ob3b757 bL4 a 2.3 The following new subclause should replace 6.2.4.3.2 in Recommendation T.433 6.2.4.

19、3.2 File transfer capabilities This parameter specifies file transfer capabilities which are available to the sender of this parameter as receiving capabilities. The parameter is present in both, the Transparent Mode and Normal Mode. - BFT (Binary File Transfer) capabilities This value indicates the

20、 capability to receive files encoded to the specification of Recommendation T.434. - Transparent data capabilities This value indicates that the sender is ready to accept (when acting as a receiver) data that are transferred completely transparently. DTM (Document Transfer Mode) capabilities This va

21、lue indicates the capability to receive BFT files (defined in Recommendation T.434) encoded to the DTM encoding rules defined in Recommendation T.563. EDIFACT (electronic data exchange) capabilities This value indicates the capability to receive files encoded to the EDIFACT formats defined in ISOIIE

This parameter is only present in the Transparent Mode. 2.5 6.5.4.1.1.6 Additional document characteristics Th

23、e value of this parameter is any combination of additional document characteristics defined in Recommendation T.414. The following new subclause should be added after 6.5.4.1.1.5 in Recommendation T.433 2.6 The following new subclauses should replace 6.5.4.1.2 in Recommendation T.433 6.5.4.1.2 File

24、transfer capabilities This parameter specifies file transfer capabilities which are available to the sender of this parameter as receiving capabilities. The parameter may be present in the Transparent Mode and Normal Mode. 6.5.4.1.3 Private capabilities See 6.2.4.3.3. 2.7 The following procedure is

25、applied to the transfer of G4 facsimile documents (according to Recommendation T.503) and to the transfer of files. The interchange data elements are to be interpreted in relationship with the T.503 document structure. In the case of file transfer, segmenting of the file will be carried out accordin

26、g to the length of the segment and the transfer procedure has to be applied accordingly to the segments of files as specified below for the interchange data elements. The following new paragraph should be inserted after the title 6.6.3.2 in Recommendation T.433 2 Recommendation T.433 I Amd.1 (08/95)

28、ndaries coincide with the minor synchronization points. Each segment consists of an integral number of interchange data elements, or in the case of file transfer, consists of the data which is subdivided into the segment of size indicated by the user. The interchange data elements of each segment ar

29、e encoded using the Basic Encoding Rules defined in Recommendation X.209. The encoded interchange data elements of each segment are concatenated, forming an encoded segment. 2.9 Figure 3 should be replaced with following new figure S-ACTIVITY-START-user-data := CHOICE ( 4 IMPLICT DocumentCharacteris
