8、mary In the B-PON system defined in ITU-T Rec. G.983.1 3 (called ATM-PON in ITU-T Rec. G.983.1), the ONTs are located at the customer site. The B-PON element management system will only manage ONTs as part of the B-PON system through the OLT using the ONT management and control interface (OMCI). Thi

9、s Recommendation presents requirements for the OMCI. Firstly, it specifies managed entities of a protocol-independent Management Information Base (MIB) that models the exchange of information between the OLT and ONT, then it covers the ONT management and control channel, protocol and detailed messag

10、es. This 2nd revised version of ITU-T Rec. G.983.2 incorporates the material from G.983.2 Amendment 1 (2003), G.983.2 Amendment 2 (2005), G.983.2 Implementers Guide (2003), G.983.6 (2002), G.983.7 (2001), G.983.8 (2003), G.983.9 (2004), G.983.10 (2004) into the base text of G.983.2 (2002). It also i

11、ncludes minor corrections, clarifications, and augmentation of functions. Source ITU-T Recommendation G.983.2 was approved on 14 July 2005 by ITU-T Study Group 15 (2005-2008) under the ITU-T Recommendation A.8 procedure. ii ITU-T Rec. G.983.2 (07/2005) FOREWORD The International Telecommunication Un

12、ion (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 Recommendations on them with a view to

13、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 approval of ITU-T Recommendations

14、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 “Administration“ is used for conciseness t

15、o 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 compliance with the Recommendation is a

16、chieved 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 required of any party. INTELLECT

17、UAL 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 Intellectual Property Rights, whethe

18、r 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. However, implementors are caut

19、ioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2006 All rights reserved.

27、cifies the ONT Management and Control Interface (OMCI) for the B-PON system defined in ITU-T Rec. G.983.1 3 (called ATM-PON in ITU-T Rec. G.983.1) to enable multi-vendor interoperability between the OLT and the ONT. The OMCI specification addresses the ONT configuration management, fault management

28、and performance management for B-PON system operation and for several services including: ATM adaptation layers 1, 2, and 5; Circuit Emulation Service; Ethernet services, including MAC Bridged LAN, VLAN tagging and filtering; Internet Protocol Routing; Wireless LAN (IEEE 802.11) service; ADSL and VD

29、SL services; Voice services, including ISDN; Wavelength division multiplexing, including video; PON protection switching; Dynamic Bandwidth Assignment; Enhanced Security. The focus of this OMCI specification is on FTTH and FTTBusiness ONTs. The Recommendation defines a protocol necessary to support

30、the capabilities identified for these ONTs. It also allows optional components and future extensions. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.
