2、6683 723 m FOREWORD The CCIT (the International Telegraph and Telephone Consultative Committee) is a permanent organ of the International Telecommunication Union (ITU). CCIT is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to stand
3、ardizing telecommunications on a worldwide basis. The Plenary Assembly of CCIT which meets every four years, establishes the topics for study and approves Recommendations prepared by its Study Groups. The approval of Recommendations by the members of CCITT between Plenary Assemblies is covered by th
4、e procedure laid down in CCITT Resolution No. 2 (Melbourne, 1988). Recommendation T.522 was revised by Study Group VI11 and was approved under the Resolution No. 2 procedure on the 18th of September 1992. CCIT NOTE In this Recommendation, the expression “Administration“ is used for conciseness to in
5、dicate both a telecommunication administration and a recognized private operating agency. O IT 1993 All rights reserved.

7、Recommendations define the open document architecture (T.4 10-Series Recommendations) and the DTAM services and protocols (T.430-Series Recommendations) for the purpose of the document transfer and manipulation. In order to apply T.400-Series Recommendations to various telematic services, it is nece
8、ssary to specify the DTAM application profile for each service that consists of a document application profile and a communication application profile. According to this requirement, T5OO-Series Recommendations define the document application profiles and T.520-Series Recommendations define the comm
9、unication application profiles. Recommendation T.522 is one of a set of T.520-Series Recommendations to define the communication application profile for the document bulk transfer using X.200 environment. Recommendation T.522 COA4MUNICATION APPLICATION PROFILE BT1 FOR DOCUMENT BULK TRANSFER (revised
10、 1992) 1 Scope and field of application This Recommendation defines the communication application profile for the document bulk transfer in a) DTAM functional units used; b) terms of DTAM service primitives and parameters used.
