ITU-T Recommendation 4.831.1 Access management for V5 Summary This Recommendation specifies an ensemble for the access management of V5. The management dom
7、ain taken into account in this Recommendation is depicted in Figure 1 and covers: o the provisioning of V5 based transport bearer services of an access network; the configuration of access network resources required for such services, and the coordination of element configuration between access netw
8、ork and service nodes. o o This Recommendation covers management operations necessary for a transmission-technology independent management of narrowband transport bearer services (PSTN, ISDN and leased line) across V5 Service Port Functions. This includes the configuration and provisioning of both V
9、5 based transport bearer services and their affected resources. Source ITU-T Recommendation 4.83 1.1 was prepared by ITU-T Study Group 4 (1 997-2000) and approved under the WTSC Resolution 1 procedure on 4 February 2000. FOREWORD The International Telecommunication Union (ITU) is the United Nations
10、specialized agency in the field of telecommunications. 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
11、 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 turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure la
12、id down in WTSC Resolution 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 Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunic
13、ation administration and a recognized operating agency. / INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. IT takes no position concerning the evidence, validit
14、y 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 Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be require
15、d 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.

21、ion Q.831.1 Access management for V5 1 General information 1.1 Scope and purpose This Recommendation specifies an ensemble for the access management of V5. The management domain taken into account in this Recommendation is depicted in Figure 1 and covers: o the provisioning of V5 based transport bea
22、rer services of an access network; the configuration of access network resources required for such a services; and the coordination of element configuration between access network and service nodes. o This Recommendation covers management operations necessary for a transmission-technology independen
23、t management of narrowband transport bearer services (PSTN, ISDN and leased line) across V5 Service Port Functions. This includes the configuration and provisioning of both V5 based transport bearer services and their affected resources. The management of User Port Functions and Service Port Functio
24、ns providing User Network Interface and Service Node Interface functionality, respectively, are considered in this Recommendation. Transmission specific resources lie outside its scope. This Recommendation provides insights into the mapping of management services onto management operations across th
25、e specified reference points. Interactions with TMN support systems such as cable management are out of scope but are taken into account as data sources within the scenarios. The process flows illustrate the information required for service provisioning management and not a physical implementation.
26、Information flows are designed as OW-enabled, i.e. applicable both for management operations within a Telecom Operator and between Telecom Operators (e.g. between Access Network Operators and Service Providers). As opposed to the standard ensemble, clauses 1 to 3 and Annex A have been written indepe
27、ndently of any TMN-protocol. The methodology used is based on the recommendations given in ITU-T Recommendation M.3020 and Unified Modelling Language (UML). The GDMO application of the ensemble is given in Annex A. The GDMO models used in the annex derive from the existing ITU-T libraries. In cases
28、where no satisfactory solution is available, the standard raises this as a work item and provides a temporary, non-normative proposal including solutions developed by industry forums. 1.2 References The following ITU-T Recommendations and other references contain provisions which, through reference

40、unction (SPF): This function adapts the specific SNI requirements into the transport bearer service (TBS): A transport bearer service provides the facilities for the 1.3.8 user access point (UAP): The location to where a service is requested and is necessary for service invocation. 1.3.9 user networ
41、k interface (UNI): The interface between the terminal equipment and a network termination at which interface the access protocols apply. 1.3.10 user port function (UPF): This function adapts the specific UNI requirements into the core and system management functions. 2 Management context 2.1 General
42、 introduction Figure 1 provides an overview of the management domain in terms of functional blocks and reference points relevant for this ensemble. This Ensemble defines in a transmission-technology independent way how the provisioning of narrowband transport bearer services (PSTN, ISDN and leased l
43、ine) is done in the management domain. Access network and service node Network Element Functions (NEF) are connected by the vreference point. For the purpose of this discussion each NEF is subdivided into an “ANSN-specific aspect“ and a “common aspect“. The previous covers functionalities specific e
44、ither to AN or SN. The latter provides functionalities required for the coordination between the Service Providers NEF and the Access Networks NEF. EAN-OSF/QAF, NAN-OSF, SAN-OSF and EsN-OSF, NsN-OSF and SSN-OSF function blocks provide element, network and service management of the access network and
45、 the service node, respectively. Two reference points a2 and a4 provide for the information exchange between the TMN of the Access Network and the Service Node. The a4 reference point allows the management of bearer transport services in the AN. The a2 reference point enables the Service Provider to
46、 request (in a restricted manner) access network resources. Both a2 and a4 provide for a simple resource coordination information exchange. The Service Providers OSFs act as managers. Figure 2 describes all reference points and possible management services in detail. The management domain necessary
47、for the interworking covers all OSFs listed above as well as those aspects of the Network Element Functions which are common to both the AN and the SN. AN-specific aspects (such as transmission management) lie outside the scope of the management domain. The same applies for SN-specific aspects such
48、as customer administration or SN-fault management. Figure 1/Q.831.1- The management domain and reference points covered in this ensemble 2.2 Figure 2 provides a detailed picture of the interactions between the Access Network Operators TMN and the Service Providers TMN. It describes the major “actors
49、“ involved in such an environment. On the AN-side the Ew-OSF/QAF manages proprietary network element functions and provides standardized reference points where relevant (al). The NAN-OSF supports transmission-technology transparent network management functions and provides appropriate management services to the SAN-OSF (a2, a4). The a2 reference point provides a restricted network level view of the access network to the Service Provider. The SAN-OSF is responsible for service management of the Access Network and provides reference points to the Service Providers SSN-OSF (a3). The SSN
