26、elecommunications services between a Service Node Interface (SNI) and one or more associated User Network Interfaces (UN). User signalling is carried transparently by the AN. ITU-T Rec. Q.833.1 (01/2001) 1 3.1.2 customer: The person or organization that uses the services provided by the network prov

27、ider or the service provider. A customer can be a service provider as well. 3.1.3 data communications network: Refers to the management communications network which is needed to transfer management information between OSFs and between OSFs and the NEs. 3.1.4 drop medium: Refers to the network used t

28、o transport services in a common format from the Remote Node to the Network Termination. 3.1.5 element management layer: EM functions manage the physical resources which reside in the access network. Typical management functions at this level are configuration, fault management and performance monit

29、oring. EM functions are responsible for understanding the details of transmission technology information and equipment thus removing the need for this complexity of information to be held by higher layer management functions. 3.1.6 elementhetworkhervice management system: The collection of functions

30、 at a specific layer which are implemented on a physical platform. 3.1.7 extended feeder: Provides the physical resources to extend the AN over larger distances. These physical resources will not alter the transmission on the SNI and will require minimal management. This is not considered to be part

31、 of the Network Element. 3.1.8 network element layer: Refers to the physical resources that reside in the Access Network. 3.1.9 network management layer: NM functions coordinate the management of network elements to provide a user-to-user or service node to user path in order to transport telecommun

32、ications services. NM Functions will coordinate multiple EM OSFs to provide overall network supervision. 3.1.10 network termination: Physical resource which resides in the customers premises and forms the boundary of the access network (UNI). Provides onward transmission of services over building wi

33、ring to customer premises equipment. 3.1.11 operations system function: This is the collection of similar functions which provide different levels of management capability. Four layers of management capability are defrned: Network Element (NE), Element Management (EM), Network Management (NM) and Se

34、rvice Management (SM). Each layer providing management services to the layer above. 3.1.12 service management layer: SM functions manage the services supported by the network. These functions are not concerned with the physical nature of the network. Typical functions of this layer are service creat

35、ion, provision, cessation, billing and accounting information. 3.1.13 service node: A network element that provides access to various switched andor permanent telecommunications services. For switched services, the Service node provides call control, connection control and resource handling function

36、s. 3.1.14 user: A crafts person interacting with the management system. 3.2 Abbreviations This Recommendation uses the following abbreviations: AAL ATM adaptation layer ADSL Asymmetric digital subscriber line AIS Alarm indication signal AN Access network ASN. 1 Abstract syntax notation one ATM Async

40、ated ASN.l defined here are given names with capitals used to indicate the start of the next word and acronyms are treated as if they were words. Throughout this Recommendation, all new attributes are named according to the following guidelines: - The name of an attribute ends in the string “Ptr“ if

41、 and only the attribute value is intended to identifj a single object. The name of an attribute ends in the string “PtrList“ if and only the attribute value is intended to identifj one or more objects. The name of an attribute is composed of the name of an object class followed by the string “Ptr“ i

42、f and only the attribute value is intended to identifj a specific object class. - - ITU-T Rec. 4.833.1 (01/2001) 3 - If an attribute is intended to identify different object classes, a descriptive name is given to that attribute and a description is provided in the attribute behaviour. The name of a

43、n attribute ends in the string “Id“ if and only the attribute value is intended to identify the name of an object, in which case this attribute should be the first one listed, should use ASN. 1 NameType and should not be used to convey other information. The name of an attribute is composed of the n

44、ame of an object class followed by the string “Id“ if and only the attribute value is intended to identify the name of the object class holding that attribute. - - 4 General overview The following information model diagrams have been drawn for the purpose of clarimg the relations between the differe

45、nt object classes of the model: 1) Entity Relationship Models showing the relations of the different managed objects. 2) Inheritance Hierarchy showing how managed objects are derived from each other (Le. the different paths of inherited characteristics of the different managed objects). These diagra

46、ms are only for clarification. The formal specification in terms of GDMO templates and ASN. 1 type definitions are the relevant information for implementations. 4.1 Entity relationship models The following conventions are used in the diagrams (see Figure 1): iscontainedin - 1 : 1 containment e 1 :N
