The ITU Telecommunication Standardization Sector (ITU-T) is a perman
11、ent 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 Telecornmunication Standardization Conference (WTSC), which meets every four years
12、, 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 WTSC Resolution No. 1. In some areas of information technology which fall w
13、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
14、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 asserted
15、 by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned
16、that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. O ITU 1998 All rights reserved.

23、NALLING LINKS (Geneva, I99 7) 1 Scope This Recommendation contains the additions and changes to Recommendation 4.75 1.1 which are necessary to manage network elements of broadband MTP including its lower layers. As a consequence it is possible to use the resulting object model for the management of
24、both SAAL (Recommendation 4.2140) - and MTP Level 2 (Recommendation 4.703; dealing with its high-speed link appendix is for further study) - signalling links. Management of mixed MTP networks is for further study. 2 Intellectual Property Rights No patent information from a patent holder concerning t
