8、cification Summary Recommendation ITU-T G.988 specifies the optical network unit (ONU) management and control interface (OMCI) for optical access networks. This Recommendation specifies the managed entities of a protocol-independent management information base (MIB) that models the exchange of infor

9、mation between an optical line termination (OLT) and an optical network unit (ONU). In addition, it covers the ONU management and control channel, protocol and detailed messages.

ITU-T G.988 (10/2012) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field o

11、f telecommunications, 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

12、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 is covered by

13、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 to indicate bot

14、h 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 achieved when

15、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. INTELLECTUAL PROPERTY

16、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, whether asserted by

17、 ITU members or others 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 m

27、commendation ITU-T G.988 ONU management and control interface (OMCI) specification 1 Scope This Recommendation specifies the optical network unit (ONU) management and control interface (OMCI) for optical access networks as defined in ITU-T G.984.x, ITU-T G.986, ITU-T G.987.x and potentially others.

28、The OMCI specification addresses ONU configuration, fault management and performance management for optical access system operation, and for several services including: GEM adaptation layers Ethernet services, including MAC bridged LAN circuit emulation service voice services. This Recommendation de

29、fines a protocol necessary to support the capabilities identified for these ONUs. 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 Re
