Q.838.1 (10/2004) i ITU-T Recommendation Q.838.1 Requirements and analysis for the management interface of Ethernet Passive Optical Networks (EPON) Summary This Recommendation is for the management of Ethernet Passive Optical Networks (EPON). The req
6、uirements and analysis for the management interface between EPON Element Management System (EMS) and Network Management System (NMS) are provided in this Recommendation, using the TMN interface specification methodology described in ITU-T Rec. M.3020. This interface is for the integrated management
7、at the network layer as well as the element layer as required. In this Recommendation, a network element view combined with a network view of EPON managed entities are modelled according to a protocol-neutral information modelling approach, and the UML use case descriptions, class diagrams and seque
8、nce diagrams are also provided for both the requirements and the analysis of this management interface. Source ITU-T Recommendation Q.838.1 was approved on 7 October 2004 by ITU-T Study Group 4 (2001-2004) under the ITU-T Recommendation A.8 procedure. ii ITU-T Rec. Q.838.1 (10/2004) FOREWORD The Int
9、ernational Telecommunication Union (ITU) is the United Nations 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 Recommen
10、dations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication 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 app
11、roval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information 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 “Administra
12、tion“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and complianc
13、e with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some 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 re
14、quired of any party. 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. ITU takes no position concerning the evidence, validity or applicability of claimed Intell
15、ectual 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 required to implement this Recommendation.
16、However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2005 All rights reserved.

20、he management interface of Ethernet Passive Optical Networks (EPON) 1 Scope This Recommendation specifies the requirements and analysis for the management interface between the Element Management System (EMS) and the Network Management System (NMS) of Ethernet Passive Optical Networks (EPON). It fol
21、lows the interface specification methodology described in ITU-T Rec. M.3020. In this Recommendation, the EMS is an Operations System (OS) used to manage the individual network elements supporting EPON technologies as well as the networks between them. One or more systems may be required depending on
22、 the different supplier products and geographic distribution of the network elements in the network. The NMS represents an integrated management OS across different technologies and supplier systems (multi-technology and multi-vendor OS). The management functions covered in this Recommendation inclu
23、de configuration management, performance measurement parameters management, and loopback test in fault management. These management functions are described and divided by UML use cases in the requirements. The analysis provides the managed entities which support a protocol-neutral information model
24、for EPON management, and also explains the static and dynamic relationships between these managed entities using UML class diagrams and sequence diagrams. This Recommendation does not cover all aspects about Ethernet management. Only those related to EPON management are addressed. 2 References The f
