8、 Recommendation M.3100 (2005), approved on 13 November 2005 by ITU-T Study Group 4 (2005-2008) under the ITU-T Recommendation A.8 procedure. ITU-T Rec. M.3100 (04/2005) ii FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunicat
9、ions. 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 telecommunications on a worldwide basis. The World Telecommunicatio
10、n 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 procedure laid down in WTSA Resolution 1. In some areas of info
11、rmation technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating age
12、ncy. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some
13、 other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or i
14、mplementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development pro
15、cess. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strong

M.3100 (04/2005) 1 ITU-T Recommendation M.3100 Generic network information model 1 Scope This Recommendation provides a ge
26、neric network information model. It identifies TMN object classes that are common to managed telecommunication networks; or are of a generic type that can be used to manage a network at a technology-independent level; or are super-classes of technology-specific managed objects in a telecommunication
27、 network; or management support objects that are required for the management of the telecommunication network. These objects are relevant to information exchanged across standardized interfaces defined in the M.3010 TMN architecture 1. This Recommendation addresses generically the abstractions of th
28、ose aspects of telecommunication resources (e.g., equipments, telecommunication services) required to manage the network. It also includes the abstractions related to the management services. ITU-T Rec. G.803, on the architecture of the transport network, is used as the basis in developing the trans
29、port aspects of this model. This Recommendation does not address abstractions relevant to technology-specific areas or implementation-specific details. 1.1 Purpose 1.1.1 Interoperability There will be a variety of TMN conformant management systems and managed systems concerning many technology-speci
30、fic areas, such as switching and transmission. One purpose of this Recommendation is to provide a vehicle for management interoperability between such systems. 1.1.2 Technology-independent management By introducing the concept of technology-independent management, it is possible to perform managemen
31、t of diverse equipment using common communication interfaces. In this manner, an “abstract“ view over a set of network-elements can be achieved. 1.1.3 Facilitating information model development This Recommendation also provides a framework from which technology-specific information models may be dev
32、eloped using the modelling principles defined in ITU-T Rec. X.720 2. 1.2 Field of application This Recommendation captures the generally applicable requirements of the technology-independent and technology-specific information models as well as information relating to TMN management services. Throug
33、h specialization, this Recommendation is applicable to technology-specific TMN information models. The mechanism for specialization is inheritance. Even though technology-specific models may be derived from this Recommendation, some of the generic managed object classes in this Recommendation are in
34、stantiable in order to provide interoperability between equipment supporting information models derived from this Recommendation and equipment that only supports the information model in this Recommendation. 2 ITU-T Rec.

41、nt: Event report management function. 3 Definitions This Recommendation defines the following terms: 3.1 General definitions 3.1.1 management interface: Any managed entity interface that is defined for the purpose of management (e.g., OS interface, craft interface, LED indicator). 3.1.2 managed enti
42、ty: A managed entity may be a managed system, a managed application, or a managed resource. This definition is dependent upon the context in which it is used. 3.1.3 managed resource: A specific component of a managed system/managed application (e.g., a specific circuit pack, termination point). 3.1.
43、4 managed resource-specific/unit audible/visual indicator: An audible/visual alarm indicator that is specific to a single managed resource. 3.2 Alarm report-related definitions 3.2.1 alarm reporting: Process of alerting, for the purposes of management, external systems and users regarding alarms. IT
44、U-T Rec. M.3100 (04/2005) 3 3.2.2 aggregate audible/visual indicators: An audible/visual alarm indicator that reflects information about a set of managed resources. 3.2.3 alarm reporting control: Involves the turning off of alarm reporting which includes inhibiting new autonomous alarm indication no
45、tification, and inhibiting the use of managed resource-specific/unit alarm information for the determination of aggregate audible/visual indicators. Autonomous alarm clear notification for previously reported alarms will not be suppressed. Alarm reporting “on“ is supported by the “ALM“ state. Alarm
46、reporting “off“ is supported by the “NALM-QI“, “NALM-TI“, and “NALM“ states. 3.2.4 ARC interval: Generic term that applies to both the persistence and timed intervals. 3.2.5 inhibited: This term is used throughout this feature description to identify that reporting is off (or in other words, is not
47、allowed). 3.2.6 persistence interval: A period of time for which a managed entity must be free of qualified problems. 3.2.7 timed interval: A period of time. 3.2.8 qualified problem: A problem that affects the operability of the managed entity and used to qualify transitions between the “NALM-NR“ an
48、d “NALM-CD“ states. Additional detail for this definition is managed resource specific and is to be defined by the managed resource. 3.3 ARC state definitions 3.3.1 ALM: ALarM reporting: Alarm Reporting is turned on. 3.3.2 NALM: No ALarM reporting: Alarm Reporting is turned off. 3.3.3 NALM-TI: No AL
49、arM reporting, Timed Inhibit: Alarm Reporting is turned off for a specified timed interval. 3.3.4 NALM-QI: No ALarM reporting; Qualified Inhibit: Alarm Reporting is turned off until the managed entity is qualified problem-free for a specified persistence interval. 3.3.5 NALM-CD: No ALarM reporting, CountDown: This is a substate of NALM-QI and performs the persistence timing countdown function when the managed entity is qualified problem-free. 3.3.6 NALM-NR: No ALarM reporting, NotReady: This is a subs
