The ITU Telecommunication Standardization Sector (ITIJ-T) is a per
12、manent organ of the ITU. 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 Telecommunication Standardization Conference (WTSC), which meets every four yea
13、rs, establishes the topics for study by the IT-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the IT-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall w
14、ithin ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGH
15、TS , The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The IT takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether assert
16、ed by IT members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, the IT had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned
17、that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. O ITU 1999 All rights reserved.

47、set of IT-T Recommendations I Intemational Standards produced to facilitate the interconnection of information processing systems. It is related to other IT-T Recommendations and International Standards in the set as defined by the Reference Model for Open Systems Interconnection (see IT-T Rec. X.20
48、0 I ISO/IEC 7498-1). The Reference model subdivides the area of standardization for interconnection into a series of layers of specification, each of manageable size. The goal of Opens Systems Interconnection is to allow, with a minimum of technical agreement outside the inter- connection standards,
49、 the interconnection of information processing systems: - from different manufacturers; - under different managements; - - of different technologies. of different levels of complexity; and This Recommendation I International Siandard specifies the connection-mode protocol for the application service element for ASO-association control: the Association Control Service Element (ACSE). The protocol for ACSE connectionless mode service (A-UNIT-DATA) is specified in ITU-T Rec. X.237 bis I ISO/IEC 15955. The ACSE provides services for establishing and releasin
