2、ommendation”) FOREWORD The -T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union (m). The -T is responsible for studying technical, operating and tariff questions and issuing Recommen- dations on them with a view to standardizing telecommunic
3、ations 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 turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the IT
4、-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993). -T Recommendation V.58 was prepared by IT-T Study Group 14 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 20th of September 1994. NOTE In this Recommendation, the expression
5、 “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. O 1994 All rights reserved.

12、ITU-T, considering (a) interfaces, basic and special functions and testing facilities; (b) enhanced management capabilities; (c) (4 (e) information; that V-Series Recommendations form a set of specifications for DCEs including the definition of external that it is expected that further Recommendatio
13、n will be published specifying newer DCEs, which offer that Recommendation M.3010 defines the principles for a Telecommunications Management Network (TMN); that Recommendation G.773 defines the protocol suites for Q-interfaces; that Recommendation M.3 100 defines a Generic Network Information Model
14、for the exchange of management recommends that the management of V-Series DCEs be carried out using the information model defined in accordance with the details contained in this Recommendation. 1 Introduction 1.1 Scope This Recommendation provides an information model for the V-Series DCEs. It iden
15、tifies the Telecommunications Management (TMN) object classes required for the management of Network Elements (NEs) defined by the Recommendations of the V-Series. These objects are relevant to information exchanged across standardized interfaces defined in Recommendation M.3010 TMN architecture. Th
16、e managed object classes in this Recommendation are specialized from the generic managed object classes defined in Recommendation M.3 1 O0 Generic Network Information model. This Recommendation does not define: - - the means by which management information may be exchanged among network elements; th
17、e network level management process. The information model defined in this Recommendation is concerned with the management of network elements, the equipment by which they are implemented and the functions contained within them. More precisely, it applies to the Equipment Domain visible at the Elemen
18、t Manager to Element interface, and is only concerned with the information available within that domain. Information proper to the domain of a Network Level Management Process is not included within this model. 1.2 Compliance Requirements The Recommendation does not require DCE behaviour that is inc
19、onsistent with other V-Series Recommendations, or with national regulatory requirements, and shall be interpreted accordingly. In order to be compliant with this Recommendation an implementation must: support at least the vSeriesDce Managed Object, if a Managed Object is supported, then at least the
20、 associated mandatory package shall be supported; if a package is supported, then all attributes, actions and notifications within the package shall be supported. If any of these relate to functions that are not implemented within the DCE, then any attempt to use the attribute or action will result
21、in nochange to the state of the DCE. - - - Recommendation V.58 (09/94) 1 1.3 Structure of this Recommendation Clause 2 provides an overview of the information model in this Recommendation. Clause 3 describes the information model using the notation mechanisms in Recommendation X.722 Guidelines for t
22、he Definition of Managed Objects. The relationships between managed object classes contained in this Recommendation are defined in clause 4. Appendix I contains some background information. 2 Information Model Overview The V-Series DCEs information model is based on the Generic Network Information m
23、odel of Recommen- dation M.3 100. The information exchanged at a management interface is modelled using design principles outlined in Recommendation X.720 Management Information Model. Resources are modelled as objects, and the management view of a resource is a managed object. Objects with similar
24、attributes may be grouped into Object classes. An object is characterized by its object class and object instance, and may posses multiple attribute types and associated values. The terms “managed object class” and “managed object instance” apply specifically to objects that are being managed. This
25、Recommendation specifies the properties of the resource visible for management. An object class may be a subclass of another Class. A subclass inherits attribute types, packages and behaviour of the super class, in addition to possessing its own specific attributes and properties. The object classes
26、 specific to the V-Series DCEs are all derived from super classes in the Generic Network Information Model Recommendation M.3 100. 3 Object Classes Object classes and attribute types are defined only for the purpose of communicating network management messages between systems, and need not be relate
27、d to the structure of data within those systems.
