G.983.2 (2005)/Amd.2 (01/2007) FOREWORD
10、 The International Telecommunication 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
11、Recommendations on them with 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.
12、 The approval of ITU-T Recommendations 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 “Ad
13、ministration“ is used for conciseness to 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 c
14、ompliance with the Recommendation is achieved 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 Recommendati
15、on is required of any party. 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 position concerning the evidence, validity or applicability of claime
16、d 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 received notice of intellectual property, protected by patents, which may be required to implement this Recommendati
17、on. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/.

G.983.2 (2005)/Amd.2 (01/2007) v Introduction The OMCI as defined in ITU-T Rec. G.983.2 continues to play an
31、important role in PON systems, both G.983 and G.984 base systems. Various new services are being introduced on these systems, such as VDSL2 and the set introduced in G.983.2 Amendment 1 (03/2006). Many modifications and additions need to be made to support and improve these services, and this is the
32、 reason for this amendment. ITU-T Rec. G.983.2 (2005)/Amd.2 (01/2007) 1 ITU-T Recommendation G.983.2 ONT management and control interface specification for B-PON Amendment 2 1) Modifications to existing clauses of G.983.2 1.1) Modify clause 2, References Modify the following reference: “ITU-T Recomm
33、endation G.997.1 (2006), Physical layer management for digital subscriber line (DSL) transceivers.“ 1.2) Modify clause 4, Abbreviations a) Modify the following 2 items: ADSL Asymmetric Digital Subscriber Line NOTE 1 The xDSL MEs include the G.992 family as well as G.993.2 VDSL2, but not G.993.1 VDSL
34、. VDSL Very High Speed DSL NOTE 2 G.993.2 VDSL2 is managed under the xDSL family of MEs. b) Add the following items in alphabetic sequence: SBC Set-by-Create xTU-C xDSL transceiver unit at the central office end (in the case of PON, the ONT/ONU), used as a generic term referring to both the ATU-C of
35、 the G.992.x series of ITU-T Recommendations and the VTU-O of ITU-T Rec. G.993.2. xTU-R xDSL transceiver unit at the remote end (subscriber premises), used as a generic term referring to both the ATU-R of the G.992.x series of ITU-T Recommendations and the VTU-R of ITU-T Rec. G.993.2. 1.3) Modify cl
36、ause 5.2, Fault management a) Replace item k) with the following: k) Physical Path Termination Point xDSL UNI; b) At the end of clause 5.2, add the following text: To avoid erratic floods of alarm messages, it is common to filter, or soak, defects such as facility impairments before declaring them a
37、s alarms, and to soak defect clearing before retiring the alarm. The declaration soak time is typically 2.5 0.5 seconds, while the retirement soak time is typically 10.5 0.5 seconds. Which alarms are to be soaked, and what the soak intervals should be, are regarded as vendor-specific choices. Intero
38、perability considerations, however, require that alarms be soaked at exactly one of the OLT or ONT, and this Recommendation specifies that they be soaked at the ONT. 2 ITU-T Rec. G.983.2 (2005)/Amd.2 (01/2007) 1.4) Modify clause 5.3, Performance management Replace items t) through x) with the follow
