9、ic in Recommendation ITU-T G.988, so that it can cover multiple access system technologies, one of which is G-PON. From January 2010, all new enhancements to the OMCI will be described in Recommendation ITU-T G.988, and so Recommendation ITU-T G.988 will be the latest and best specification. The poi
10、nt of this amendment is to direct the readers of Recommendation ITU-T G.984.4 to consult Recommendation ITU-T G.988 as their primary reference. That said, Recommendation ITU-T G.984.4 remains “in-force“ for those features that are not covered in Recommendation ITU-T G.988. History Edition Recommenda

ITU-T G.984.4 (2008)/Amd.3 (07/2010) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications
13、, information and communication technologies (ICTs). 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 o
14、n 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 is covered by the procedure laid d
15、own 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 to indicate both a telecommunicatio
16、n 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 achieved when all of these mandato
17、ry 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. INTELLECTUAL PROPERTY RIGHTS ITU draws att
18、ention 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, whether asserted by ITU members or othe
19、rs outside 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, implementers are cautioned that this may not represent the
20、 latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2010 All rights reserved.

From January 2010, all new enh
23、ancements to the OMCI will be described in ITU-T G.988, and so ITU-T G.988 will be the latest and best specification. The point of this amendment is to direct the readers of Recommendation ITU-T G.984.4 to consult ITU-T G.988 as their primary reference. That said, Recommendation ITU-T G.984.4 remain
24、s “in-force“ for those features that are not covered in ITU-T G.988. 2 Changes to ITU-T G.984.4 (2008) 2.1 Modification to “Summary“ Replace the summary with the following: “The most up-to-date specification for the ONT management and control interface (OMCI) now appears in Recommendation ITU-T G.98
25、8. Readers with a continuing interest in OMCI are advised to consult Recommendation ITU-T G.988 as their primary reference. Recommendation ITU-T G.988, the generic OMCI specification, is intended to cover a variety of access systems, including G-PON. However, Recommendation ITU-T G.988 does not docu
26、ment all of the legacy features that were contained in Recommendation ITU-T G.984.4. Definitions and features contained in Recommendation ITU-T G.984.4 that do not appear in Recommendation ITU-T G.988 remain valid for legacy ITU-T G.984 applications. Further, all code points assigned to such legacy
27、definitions remain reserved and are excluded from the code points assignable by Recommendation ITU-T G.988.“ 2.2 Modification to clause 1, Scope Add the following text to the beginning of clause 1: “The most up-to-date specification for the ONT management and control interface (OMCI) now appears in
28、ITU-T G.988. Readers with a continuing interest in OMCI are advised to consult ITU-T G.988 as their primary reference. For items where Recommendation ITU-T G.984.4 (2008, as amended) and ITU-T G.988 conflict, ITU-T G.988 takes precedence. However, for legacy items specified by Recommendation ITU-T G
29、.984.4, where ITU-T G.988 remains silent, then the Recommendation ITU-T G.984.4 material remains in force. Further, all code points assigned to such legacy definitions remain reserved and are excluded from the code points assignable by ITU-T G.988.“ 2 Rec. ITU-T G.984.4 (2008)/Amd.3 (07/2010) 2.3 Mo
