13、s Supplement 4 (06/2016) 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) is a permanent organ of ITU. ITU-
14、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 years, establishes the topics for stud
15、y 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 necessary standards are prepared on a c
16、ollaborative basis with ISO and IEC. NOTE In this publication, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this publication is voluntary. However, the publication may contain certain ma
17、ndatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the publication 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. Th

23、ding data fields are formally defined in ITU-T H.225.0. Individual feature specifications define the meaning and content of those fields for specific features. Recommendation ITU-T H.460.1 gives some guidance on the usage of GEF. This Supplement to Recommendation ITU-T H.460.1 lists generic paramete
24、rs assigned in the ITU-T H.460.x series Recommendations. Its purpose is to provide a quick reference to those parameters. This supplement will be regularly updated as new ITU-T H.460.x Recommendations appear. 2 References ITU-T H.225.0 Recommendation ITU-T H.225.0 (2009), Call signalling protocols a

27、ing Rules 4 Generic identifier assignment GEF can be used for standard and non-standard features. Each feature and each parameter defined in the context of such a feature are unambiguously identified by an identifier (ID). Standard features are specified in the ITU-T H.460.x series of Recommendation
28、s, with some exceptions where a feature is defined in an annex to another Recommendation, and generally use integer values as identifiers. Non-standard features may be defined by an organization other than ITU-T or by a vendor, a service provider, etc. They use object IDs or non-standard parameters
29、as identifiers. In any case, the feature specification also assigns the identifiers used by that feature. 2 H series Supplement 4 (06/2016) This Supplement lists the identifiers assigned to date for standard GEF features, i.e., features defined by ITU-T. 5 List of identifiers 5.1 Feature identifiers
30、 The identifier n of a feature is the same as the final part in Recommendation ITU-T H.460.n, the designation of the Recommendation defining that feature. Feature identifiers are used at the top level of a genericData structure or of a featureDescriptor within a featureSet. Feature ID Feature name D

Therefore, parameter identifiers appear on a level below a feature identifier. Parameters may carry content in addition to the identifier. However, for featu
38、re negotiation (i.e., inside a featureSet), parameters will be included as identifiers without content.
