9、elecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (IT-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on th

10、em 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 IT-T study groups which, in turn, produce Recommendations on these topics. The approval of -T Re

11、commendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within IT-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for

12、conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS 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 pos

13、ition 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 had not received notice of intellectual property, prot

14、ected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. o ITU 2001 All rights reserved.

36、 that wish to provide a service of transparent transport of information (e.g. the case where existing information elements are defined for the transport of certain information) as well as having the ability of passing additional network-related information within the public network, then the followi

37、ng guideline is provided: ITU-T Q.763/Arnd.l(03/2001) 5 It is suggested that this field be structured such that the first octet (i.e. first octet of rst segment for long APM-user information) is a pointer to information to be transported transparently. The pointer value (in binary) gives the number

38、of octets between the pointer itself (included) and the first octet (not included) of transparent data. The pointer value “all zeros“ is used to indicate that no transparent data is present. The range of octets between the pointer octet and the fust octet of transparent data (to which the pointer oc

39、tet points) contains the network-related information to be passed between the applications residing within the public network. The format and coding of both the transparent information and the network-related information is application-specific and defined in the appropriate Recommendation. 6 ITU-T Q.763/Amd.l(03/2001)
