Source Recommendation ITU-T J.800.2 was approved on 13 June 2008 by ITU-T Study Group 9 (2005-2008) under Recommendation ITU-T A.8 procedure. ii Rec. ITU-T J.800.2 (06/2008) FOREWORD The International Telecommunication Union (ITU) is th
4、e United Nations specialized agency in the field of 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 Rec
5、ommendations 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. Th
6、e 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 “Admin
7、istration“ 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 comp
8、liance 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 Recommendation
9、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 claimed I
10、ntellectual 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, protected by patents, which may be required to implement this Recommendat
11、ion. 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/.

13、ec. ITU-T J.800.2 (06/2008) 1 Recommendation ITU-T J.800.2 Cable definition MIB specification 1 Scope This Recommendation describes the namespace organization for the Cable industry enterprise MIB. It defines Cable Definition MIB modules whose purpose is to centrally allocate Object Identifiers (OID
14、s) for cable and, as such, to provide the private layout of the cable industry Object Identifier structure. There are regional differences in the general service environment where cable industry technologies are deployed which lead to varying requirements for the organization of the namespace of the
15、 cable industry enterprise MIB. Therefore, two options for the namespace organization are included that have equal priority and are not required to be implemented in parallel nor to be interoperable. The first of these options is defined in clause 4 and provides the Cable Definition MIB module (CLAB
16、-DEF-MIB) to be applied for cable technology implementing the technology option adapted to a service environment like in North America. For the second technology option, the content of clause 4 is replaced by the content of Annex A. It defines two Definition MIB modules (ECL-DEF-MIB and EXCENTIS-MIB
17、) and is to be applied in service environments like those found in Europe. Compliance with this Recommendation requires compliance with the one or the other of these options, not with both. It is not required that equipment built to one option interoperates with equipment built to the other. NOTE Th
18、e structure and content of this Recommendation have been organized for ease of use by those familiar with the original source material; as such, the usual style of ITU-T recommendations has not been applied. 2 References This Recommendation is referenced by several Cable industry projects including
19、DOCSIS, IPCable2Home, and IPCablecom. It defines the Cable OID registry from which each project assigns its own MIB information modules. As such, the Cable Definition MIB constitutes a normative reference to several Cable industry Recommendations, including those listed below. DOCSIS Specifications
