Keywords Dedicated and Reconfigurable Circuits Network, Leased Circuits, Leased Circuit Services, Telecommunications Management Networks (TMN), TMN Management Service. STD-ITU-T RECMN M-3208*1-ENGL 1777 48b2571 Ob1i5201 2T4 m FOREWORD ITU (Interna
9、tional Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommend
10、ations on them with a view to standardizing telecommunications 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.
11、The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 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 Recommend
12、ation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use
13、 of a claimed Intellectual Property Right. The 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 process. As of the date of approval of this Recommendat
14、ion, the 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 strongly urged to consult the TSB patent database. O I

27、ASED CIRCUIT SERVICES (Geneva, 1997) 1 Introduction This management service is related to the two phases of the service life cycle of a leased circuit service: pre-service This phase starts when the Service Customer (SC) requests the creation of a service and lasts until the completion of the reques
28、ts is reported to the SC. When the required facilities are present, the completion may be immediate and no interaction takes place between the SC and service provider between the request and the response. When completion is not immediate, the provisioning phase ends with the Report create completion
29、 function from the service provider. During the provisioning phase the SC may: a) modify service request parameters; b) retrieve service request parameters; cl d) cancel the service request. During the provisioning phase, the service provider may report configuration change. in-service query the sta
30、tus of the service request; The in-service (operation) phase follows the provisioning phase and lasts until the service is deleted either by the SC or the Service Provider (SP). 1.1 Scope This Recommendation describes a subset of TMN management services for Dedicated and Reconfigurable Leased Circui
31、ts network identified in the Recommendation M.3200 as a TMN managed area. Its main focus is on the management services of Customers Administration and Maintenance management for the point-to-point Leased Circuit Services (LCSs) that may be offered by one or more service providers and may be controll
32、ed by the SC with different levels of visibility. The LCS is defined between a single SC and a single SP. These management services are also applicable for interactions between management systems of different service providers or within a service provider. TMN management services in this Recommendat
33、ion specie interface requirements for Leased Circuit Services between an Operations System (OS) and an Operations System (OS) to provision and manage Leased Circuit Services. The interfaces addressed by the TMN management services in this Recommendation are applicable to both X Interfaces across jur
34、isdictional boundaries and 43 within a TMN. Support for the services described in this Recommendation is at the discretion of the Service Provider. Recommendation M.3208.1 (10/97) 1 The TMN management services in this Recommendation are described using GDMS template contained in the Recommendation M
35、.3020. In general, the definition of a service should be independent of the particular network used to transport the service. This allows multiple technologies to support the service. Therefore, network level information should not be presented to the service layer. However, specific service feature
36、s may be defined which allow network or network element information to be presented to a service customer. In this case, an abstraction of the information appropriate to the service feature is transferred. The requirements for International LCS are not included in this Recommendation. Clause 2 provi
37、des the requirements for security of the Leased Circuit Service (LCS). Clause 3 provides the requirements for customer administration of the LCS. This includes configuration and status administration of Dedicated LCS and Reconfigurable LCS. Clause 4 addresses the maintenance management requirements
38、for LCS. Appendix I provides enterprise viewpoint per Recommendation G.85 1 for the Leased Circuit Service. Appendix II provides management scenario examples. Appendix III shows some topological examples of LCS. 1.2 Related Recommendations The following Recommendations should be referred to in conne

44、efinitions This Recommendation defines the following terms: 1.4.1.1 contract: A contract is a formalized business agreement between a customer and a provider. A contract may be either internal, that is, between a SC and service user, or external, i.e. between a service provider and a SC. An internal
45、 contract is not subject to standardization. 1.4.1.2 leased circuit service: The Leased Circuit Service is a telecommunications service that provides for the transmission of information between two or more service access points in a layer network. A service access point can either be at a customer p
46、remise or within the network. This Recommendation is limited to Leased Circuit Services with two access points. These types of Leased Circuit Services are termed point-to-point leased circuit services. The transmission resources used to provide the service must meet the parameters and conditions spe
47、cified in the contract. The underlying technology that supports the transmission path may use one or more technologies (e.g. SDH, PDH, ATM, Frame Relay) as long as the contract for the service is met. The Leased Circuit Service may be specialized. See Dedicated Leased Circuit Service and reconfigura
48、ble Leased Circuit Service. NOTE - This Recommendation is limited to leased circuit services with two access points. These types of leased circuit services are generally termed point-to-point leased circuit services. The terms “Originating Location“ and “Terminating Location“ refer to the A and Z ac
49、cess points for the LCS. For bi-directional LCSs, the terms “Originating“ and “Terminating“ have no semantic meaning. 1.4.1.3 dedicated leased circuit service: The dedicated leased circuit service is a point-to-point connection between two service access points which cannot be changed after creation of the service . The Dedicated LCS uses the Service Name and Service Class to define the value for service specific parameters and to designate which parameters may be changed by the SC following provisioning of the service.
