Summary This Recommendation provides an information model for the synchronous digital hierarchy (SDH). This model describes the managed object classes and their properties that are useful to

8、describe information exchanged across interfaces defined in ITU-T M.3 O 1 O telecommunications management network (TMN) architecture. This Recommendation specialises the generic object classes of ITU-T M.3 100 to provide management information specifically for the SDH. 0911 992 I Document history In

9、itial version of the Recommendation. 7 Issue I Notes I I Source ITU-T Recommendation G.774 was revised by ITU-T Study Group 15 (2001-2004) and approved under the WTSA Resolution 1 procedure on 9 February 2001. ITU-T G.774 (02/2001) i FOREWORD The International Telecommunication Union (ITU) is the Un

10、ited Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telec

11、ommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the p

12、rocedure laid down in WTSA Resolution 1. In some areas of information technology which fall within 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 t

13、elecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidenc

14、e, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may

15、be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. O ITU 2002 All rights reserved.

34、provides an information model for the synchronous digital hierarchy (SDH). It identifies the telecommunications management network (TMN) object classes required for the management of SDH network elements. These objects are relevant to information exchanged across standardized interfaces defined in I

35、TU-T M.3010 TMN architecture. The managed object classes in this Recommendation are specialized from the generic managed object classes defined in ITU-T M.3 1 O0 generic network information model. This Recommendation applies to SDH network elements and those systems in the TMN that manage SDH networ

36、k elements. Functional capabilities of SDH multiplex equipment are given in ITU-T G.783, and aspects of the management of SDH equipment are provided in ITU-T G.784. This Recommendation provides the management information required for use with the protocols specified in ITU-T G.784. The new objects d

37、efined in this Recommendation supersede those defined in the previous version of the Recommendation (i.e. the 1992 version). For each object class, attribute, action, notification, parameter defined in this version of the Recommendation, it shall be indicated what the impacts are upon the existing I

38、TU-T G.774 (1992). Structure of this Recommendation Clause 5 provides an overview of the SDH information model. Clauses 6 to 9 describe the information model using the notation mechanisms defined in ITU-T X.722 Guidelines for the definition of managed Objects. Section 10 contains the syntax definiti

39、ons of the information carried in the protocol using Abstract Syntax Notation One (ASN. 1) defined in ITU-T X.680-X.683. The relationships between the SDH managed object classes contained in this Recommendation are defined in clause 11. Diagrams illustrating the construction of the SDH model are pro
