G.983.1 1 for select functions which were out of the scope of ITU-T Rec. G.983.2 2. OMCI support is specifie

Source ITU-T Recommendation G.983.8 was prepared by ITU-T Study Group 15 (2001-2004) and approved under the A.8 procedure on 16 March 2003. ii ITU-T Rec. G.983.8 (03/2003) FOREWORD The International Telecommun
11、ication 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 Recommendations on them with
12、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 approval of ITU-T Recomm
13、endations 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 con
14、ciseness to indicate both a telecommunication 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. ITU takes no po
15、sition concerning the evidence, validity 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, pro
16、tected by patents, which may be required 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. ITU 2003 All rights reserved.

23、 support for IP, ISDN, video, VLAN tagging, VC cross-connections and other select functions 1 Scope This Recommendation focuses on the OMCI specifications related to support for IP Router functionality on LAN cards, ISDN, additional Ethernet performance monitoring, video interfaces, VLAN tagging, ex
24、tended MAC Bridge Filtering, local craft terminal interfaces, VC cross-connections, and ONUs (detailed management for ONUs with xDSL interfaces is for future study). Though the OMCI specifications are based on ITU-T Rec. G.983.2 2, some enhancements are needed. The scope of this Recommendation is li
25、mited to the enhancements only. This Recommendation includes additions and editorial changes to sections of ITU-T Rec. G.983.2 2 that pertain to these topics. As this Recommendation serves as an extension of ITU-T Rec. G.983.2 2, all sections of that Recommendation remain pertinent. 2 References The
