ITU-T J.168 (03/2001) i ITU-T Recommendation J.168 IPCablecom media terminal adapter (MTA) MIB requirements Summary This Recommendation describes IPCablecoms Media Terminal Adapter (MTA
7、) MIB requirements. Source ITU-T Recommendation J.168 was prepared by ITU-T Study Group 9 (2001-2004) and approved under the WTSA Resolution 1 procedure on 9 March 2001. ii ITU-T J.168 (03/2001) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the
8、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 a view to standardizing telecommunications on a worldwide basis. The
9、 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 the procedure laid down in WTSA Resolution 1
10、. 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 both a telecommunication administration and a r
11、ecognized 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 position concerning the evidence, validity or applicability of claimed
12、 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, protected by patents, which may be required to implement this Recommend
13、ation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2002 All rights reserved.

23、 defines the following terms: 3.1 cable modem: A cable modem is a layer-two termination device that terminates the customer end of the J.112 connection. 3.2 IPCablecom: An ITU-T project that includes an architecture and a series of Recommendations that enable the delivery of real time services (such
24、 as telephony) over the cable television networks using Cable Modems. 3.3 Management Information Base (MIB): the specification of information in a manner that allows standard access through a network management protocol. 3.4 MUST: The term “MUST“ or “MUST NOT“ is used as a convention in the present
25、Recommendation to denote an absolutely mandatory aspect of this Recommendation. 4 Abbreviations This Recommendation uses the following abbreviations: MIB Management Information Base MTA Media Terminal Adaptor 5 Requirements This clause defines the mandatory syntax of the IPCablecom MTA MIB. It follo
26、ws the IETF Simple Network Management Protocol (SNMP) for defining the managed objects. The MIB is organized as follows: MTA device objects; MTA security objects; objects used for initial provisioning and bootstrapping; objects used for event reporting to syslog, trap, local local The syntax is give
