2、LS ITU-T Recommendation T.436 (Previously “CCITT Recommendation”) ITU-T RECNN*T=436 95 4862573 Ob06533 841 FOREWORD The ITU-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union (ITU). The ITU-T is responsible for studying technical, operating
3、 and tariff questions and issuing Recommen- dations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their tu
4、rn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993). ITU-T Recommendation T.436 was prepared by ITU-T Study Group 8 (1993-1996) and was approved under the
5、WTSC Resolution No. 1 procedure on the 1 lth of August 1995. NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

It defines the protocol of two new applications service elements for interactive confir
10、med document manipulation. aligned with, and provided for, the integrated use with applications defined under the Distributed Office Application Model (DOAM). The two application service elements are the DTAM-TM and DTAM-TK. The use of the DTAM-DM application service element is mandatory for documen
11、t manipulation applications and is used in conjunction with the ACSE and ROSE services elements. Optionally, it may be combined with the DFR-SE (for filing and retrieval purposes) and with the DTAM-TK service element for exchange of an application token in multi-user conferences. 11 Recommendation T

13、vice elements DTAM-DM and DTAM-TK. The DTAM-DM abstract services provide facilities to allow remote operations on any kind of documents or document fragments. The DTAM-TK application service element provides for the handling of an application token to structure a dialogue, if two or more users are i
14、nvolved in conference type of applications. This Recommendation specifies the protocols between DTAM users which apply the DTAM-DM or the DTAM-TK abstract services. This Recommendation does not specify individual implementations or products, nor does it contain the implementation of entities or inte
15、rfaces within a telematic system. 2 References The following Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.
