It is the intention of this standard to continue to use and align with Open Systems Interconnection (OSI) man-agement standards, where appropriate. 1.2 Purpose Current telecommunications networks are populated by a large and increasing num

7、ber of OSs and NEs supplied by different vendors. Both the number and variety of networks and services have grown, creating a diversity of network management needs. This growth has resulted in the proliferation of unique communication interfaces between OSs and NEs. The telecommunications industry s

8、tands to benefit from standardization of these interfaces, designed to ATIS-0300240.2014 2 achieve interoperability between a broad range of OSs and NEs.

This document makes use of the following term def

10、ined in ATIS-0300208: OAM the latter includes portions that may be assigned for exclusive use by specific customers. Resources may be physical or logical in nature. Physical resources include customer (e.g., PBXs) or provider (e.g., digital cross connect systems) systems, their associated subsystems

11、 (e.g., ATIS-0300240.2014 5 a line card within a PBX), and also the links that interconnect these systems. Such systems are generally known as Network Elements (NEs). Logical resources include communication protocols, application programs, logs, and network services. There may also exist (separate o

12、r integrated) Telecommunications Management Network (TMN) ATIS-0300210 resources involved in operating a telecommunications network. These resources include the OSs closely associ-ated with managing specific NEs and OSs that have network-wide responsibilities. Resources allow the user to control and

13、/or observe their behaviour. The information exchanged at the management interface is modelled using design principles outlined in ITU-T Recommendation X.720. Resources are modelled as objects, and the management view of a resource is called a managed object. Additional objects, called support manag

14、ed objects, are defined to support the functions of managing a telecommunications network. This generic network information model contains definitions for generic object classes that may be applicable across technologies and functional areas. 6 Object Classes CHARACTERIZED BY servicePackage PACKAGE

15、BEHAVIOUR serviceBehaviour BEHAVIOUR DEFINED AS “The service object class is a class of managed objects that represents offerings from a provider that supply specific network functionality to one or more customers. A Service may or may not be tariffed. Services may be nested, thereby creating a cont

16、ainment relationship. The Service Type identifies the distinguishing characteristics of the Service. The Supported Ser-vice Name List identifies other Services supported by the Service, and the Supported By Object List identifies the objects that support the Service” ; ATTRIBUTES serviceID GET, serv

31、onformance ITU-T Recommendation M.3101 defines management conformance requirements of the Generic Network Infor-mation Model defined in ITU-T Recommendation M.3101. However, M.3101 does not define conformance re-quirements for management information that is referenced in ITU-T Recommendation M.3100.

32、 ATIS-0300240.2014 12 This standard is intended to provide a network model to support the implementation of standardized messages for OSNE interfaces. It is therefore intended to be used with the associated message specification standards. The complete set of conformance requirements for standardize

33、d OSNE messages is given in the conformance section of those standards. Where other telecommunications standards import any of the definitions contained in this standard, such references shall comply with the behavioral and syntactic aspects of those types to the extent specified in this standard. W

34、here other standards refine any of the object class definitions contained in this standard via the refinement and referencing mechanisms defined in ITU-T Recommendation X.722, the object classes that refine these definitions shall comply with the behavioral and syntactic aspects of the superclass to

35、 the extent defined in this standard. ATIS-0300240.2014 13 Annex A (informative) A Bibliography At the time of publication of this standard, the editions of the following references were valid.
