ITU-T Rec. G.983.10 (06/2004) i ITU-T Recommendation G.983.10 B-PON ONT management and control interface (OM
8、CI) support for Digital Subscriber Line interfaces Summary This Recommendation focuses on the OMCI specifications related to support for ONUs with ADSL and VDSL interfaces. In the B-PON system defined in ITU-T Rec. G.983.1 1, the ONTs are located at the customer site and the ONUs are generally locat
9、ed at the curb or cabinet. The B-PON element management system will only manage ONTs/ONUs as part of the B-PON system through the OLT using the ONT management and control interface (OMCI). The OMCI specifications are based on ITU-T Rec. G.983.2 2. Some enhancements are needed for the support of ADSL
10、 and VDSL interfaces. This Recommendation covers configuration, fault and performance management enhancements to ITU-T Rec. G.983.2. Attributes are taken from the G.99x series of Recommendations which relate to DSL technology. This Recommendation uses the approach described in ITU-T Rec. G.983.8 whi
11、ch focuses on other interfaces. Source ITU-T Recommendation G.983.10 was approved on 13 June 2004 by ITU-T Study Group 15 (2001-2004) under the ITU-T Recommendation A.8 procedure. ii ITU-T Rec. G.983.10 (06/2004) FOREWORD The International Telecommunication Union (ITU) is the United Nations speciali
12、zed 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 on a wo
13、rldwide 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 is covered by the procedure laid down in
14、 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 to indicate both a telecommunication admi
15、nistration 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 achieved when all of these mandatory provi
16、sions 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. INTELLECTUAL PROPERTY RIGHTS ITU draws attention t
17、o 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, whether asserted by ITU members or others outsi
18、de of the Recommendation development process. As of the date of approval of this Recommendation, ITU had 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
19、information and are therefore strongly urged to consult the TSB patent database. ITU 2004 All rights reserved.

22、ion G.983.10 B-PON ONT management and control interface (OMCI) support for Digital Subscriber Line interfaces 1 Scope This Recommendation focuses on the OMCI specifications related to support for ONUs with ADSL and VDSL interfaces. Though the OMCI specifications are based on ITU-T Rec. G.983.2 2 and
23、 ITU-T Rec. G.983.8 3, some enhancements are needed. The scope of this Recommendation is limited to the enhancements only. An alternative management protocol for ONUs with ADSL and VDSL interfaces consists of carrying an SNMP MIB structure transparently over the PON. This alternative solution is not
24、 documented here. This Recommendation includes additions to sections of ITU-T Rec. G.983.2 that pertain to these topics. As this Recommendation serves as an extension of ITU-T Rec. G.983.2, all sections of that Recommendation remain pertinent. The ADSL managed entities specified in this Recommendati
25、on are modelled after ITU-T Rec. G.997.1 (and its Amendment 1). The VDSL managed entities specified in this Recommendation are modelled after the IETF RFC 3728. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute
26、provisions of this Recommendation. At the time of publication, the editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommen
27、dations and other references listed below. A list of the currently valid ITU-T Recommendations is regularly published.
