J.166 (12/2007) i ITU-T Recommendation J.166 IPCablecom Management Information Base (MIB) framework Summary ITU-T Recommendation J.166 describes the framework in which IPCablecom MIBs (management information base) are defined. It provides information on the management requirements of I
3、PCablecom-specified devices and functions and how these requirements are supported in the MIB. It is intended to support and complement the actual MIB Recommendations, which are included as annexes.

4、 under the ITU-T Recommendation A.8 procedure. ii ITU-T Rec. J.166 (12/2007) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardizat
5、ion 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 on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which mee
6、ts 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 down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts
7、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 telecommunication administration and a recognized operating agency. Compliance with this Recommendation is
8、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 mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and
9、 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 attention to the possibility that the practice or implementation of this Recommendation may invo
10、lve 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 others outside of the Recommendation development process. As of the date of approval of this Reco
11、mmendation, ITU had not 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 latest information and are therefore strongly urged to consult the TSB patent database a

36、Base MTA Media Terminal Adapter NCS Network Call Signalling QoS Quality of Service 4.2 Conventions Throughout this Recommendation, the words that are used to define the significance of particular requirements are capitalized. These words are: “MUST“ This word or the adjective “REQUIRED“ means that t
37、he item is an absolute requirement of this Recommendation. “MUST NOT“ This phrase means that the item is an absolute prohibition of this Recommendation. “SHOULD“ This word or the adjective “RECOMMENDED“ means that there may exist valid reasons in particular circumstances to ignore this item, but the
38、 full implications should be understood and the case carefully weighed before choosing a different course. “SHOULD NOT“ This phrase means that there may exist valid reasons in particular circumstances when the listed behaviour is acceptable or even useful, but the full implications should be underst
39、ood and the case carefully weighed before implementing any behaviour described with this label. “MAY“ This word or the adjective “OPTIONAL“ means that this item is truly optional. One vendor may choose to include the item because a particular marketplace requires it or because it enhances the produc
40、t, for example; another vendor may omit the same. 4 ITU-T Rec. J.166 (12/2007) 5 Overview IPCablecom MIB modules are designed to provide necessary functionality defined in IPCablecom Recommendations. MIBs that are developed for IPCablecom support embedded media terminal adapters (MTAs) and in most c
41、ases stand-alone MTAs and provide definitions for call signalling and MTA device provisioning functions. Future IPCablecom development phases will include other functional areas as well as requirements for other IPCablecom components, which will be considered for MIB module development. IPCablecom f
42、unctional areas that are being studied for future IPCablecom MIB definition include ITU-T Rec. J.161, ITU-T J.162, ITU-T J.167, ITU-T J.170 and ITU-T J.176. Additionally, in this specification, the term “DOCSIS“ is used to refer to DOCSIS version 1.1 ITU-T J.112, DOCSIS version 2 (ITU-T Rec. J.122)
43、or DOCSIS version 3 (ITU-T Recs J.21x and J.22x series), unless explicitly specified otherwise. 5.1 IPCablecom reference architecture The conceptual diagram for the IPCablecom architecture is shown in Figure 1. Please refer to ITU-T J.160 for more detailed information concerning the IPCablecom archi
44、tecture. Figure 1 IPCablecom network component reference model (partial) 5.2 General requirements The IPCablecom MIBs Framework Recommendation follows the Internet Standard Management Framework described in IETF RFC 3410. Additionally, the following requirements have been considered in the design of
45、 IPCablecom MIB modules: IPCablecom devices MUST be compliant with DOCSIS; Therefore, IPCablecom devices must support DOCSIS MIBs as defined in clause 6.1; take a minimalist approach for design of the IPCablecom MIB modules, i.e., if other MIB modules define the same functions, then rely on these MI
46、B modules rather than create new ones; organize MIB modules to support both embedded and stand-alone MTAs; organize MIB modules so as to allow functional partitioning of ITU-T Rec. J.112/J.122 (high-speed data) and IPCablecom (voice features); DOCSIS within IPCablecom applications requires support o
47、f SNMPv3; therefore IPCablecom MIB agents MUST comply with SNMPv3; ITU-T Rec. J.166 (12/2007) 5 IPCablecom MIBs MUST comply with SMIv2 as defined in IETF STD 58. 5.2.1 Provisioning and network management service provider A single physical device (e.g., embedded-MTA) will be completely provisioned an
48、d managed by a single business entity. In the case of multiple service providers offering different services on the same device (e.g., data by one provider, voice by another provider), a secondary service provider will act as the “contractor“ for the primary provider in the areas of device provision
49、ing and management. See Figure 2. Figure 2 Partitioning of management domains 5.2.2 Support for embedded and stand-alone MTAs The IPCablecom MIBs will provide features for both embedded and stand-alone MTAs. Since stand-alone MTAs are not required to include any CM related functions, the IPCablecom MIBs, therefore, should be independent of CM and able to provide management support for voice communications functionalities. Cable modems with embedded MTAs must adhere to the DOCSIS or eDOCSI
