8、.350.3 Directory services architecture for H.320 Summary Recommendation ITU-T H.350.3 describes a lightweight directory access protocol (LDAP) schema to represent ITU-T H.320 endpoints. It is an auxiliary class related to Recommendation ITU-T H.350 and derives much of its functionality from that arc

9、hitecture. Implementers should review Recommendation ITU-T H.350 in detail before proceeding with this Recommendation. Its attributes include basic ITU-T H.320 address elements. These addresses can be downloaded to an endpoint for automatic configuration or published to white pages to create user di

10、alling directories. The scope of this Recommendation does not include normative methods for the use of the LDAP directory itself, or the data it contains. The purpose of the schema is not to represent all possible data elements in the ITU-T H.320 protocol, but rather to represent the minimal set req

11、uired to accomplish the design goals enumerated in Recommendation ITU-T H.350. This revised version of Recommendation ITU-T H.350.3 introduces several enhancements and clarifications to the previous version, primarily addition of ITU-T X.500 directories support. This Recommendation includes an elect

13、3, LDAP, SIP, ITU-T X.500. ii Rec. ITU-T H.350.3 (05/2011) 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 Standardization Sector (ITU-T)

14、 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 meets every four year

15、s, 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 purview, the neces

16、sary 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 voluntary. However

17、, 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 the negative eq

18、uivalents 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 involve the use of a

19、 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 Recommendation, ITU

20、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 at http:/www.itu.

These addresses can be downloaded to an endpoint for automatic configuration or published to white pages to create user dialling directories. The scope of this Recommendation does not include normative methods f

26、or the use of the LDAP directory itself, or the data it contains. The purpose of the schema is not to represent all possible data elements in the ITU-T H.320 protocol, but rather to represent the minimal set required to accomplish the design goals enumerated in ITU-T H.350. 1.1 Extending the schema

27、The h320Identity classes may be extended as necessary for specific implementations. See the base ITU-T H.350 for a discussion on schema extension. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of

37、edia conferencing endpoints. 3.2 endpoint: A logical device that provides video and/or voice media encoding/decoding, and signalling functions. Examples include: 1) a group teleconferencing appliance that is located in a conference room; 2) an IP telephone; 3) a software program that takes video and

38、 voice from a camera and microphone, encodes it and applies signalling using a host computer. Note that from the perspective of most signalling protocols, gateways and MCUs are special cases of endpoints. 3.3 white pages: An application that allows end users to look up the address of another user. 4
