5、ernational 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-T is responsible for studying technical,
6、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 study by the ITU-T study groups which, in tur
7、n, 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 collaborative basis with ISO and IEC. NOTE
8、 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, the Recommendation may contain certain mandatory provisions (to ensure e.
9、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 equivalents are used to express requirements. The use of such words does not su
10、ggest that compliance with the Recommendation is required of any party.

17、-T J.460.1 IPCablecom2 residential SIP telephony: Feature specification 1 Scope This Recommendation specifies an implementation of common residential telephony features in an IPCablecom2 network with SIP based User Equipment (UEs). These features include the most commonly used residential features a
18、nd capabilities, including Caller ID features, call forwarding features, hold, transfer, three-way calling, emergency calling, and operator services. The IPCablecom2 network architecture uses the Session Initiation Protocol (SIP) as the basis for call setup and teardown. SIP was designed to permit d
19、istribution of feature logic to the network endpoints, requiring less processing in network elements, and theoretically permitting a reduction in cost of network infrastructure. Also, SIP was designed to support a wide range of interactive applications, including telephony, video conferencing, inter
20、active messaging, presence, wireless services, and many others. Lastly, SIP is the foundation of the IP Multimedia Subsystem (IMS) architecture, upon which the IPCablecom2 architecture is based. Many telecom equipment and software suppliers are focusing their investments in converged network solutio
21、ns on the IMS architecture, and the IPCablecom2 architecture leverages the IMS architecture, which should yield more rapid implementation timeframes. This initial Residential SIP Telephony Feature Specification defines the Layer 3 and higher network requirements and signaling to enable User Equipmen
22、t (UE) to establish services to emulate historical analog telephony services and features. This release of the Recommendation supports services described in Appendix II of RST TR. Future releases will support additional services that are described in Appendices I and III of RST TR as they are develo
23、ped. It is an important objective of this work that interoperability between IPCablecom 2.0 and 3GPP IMS is provided. IPCablecom 2.0 is based upon 3GPP IMS, but includes additional functionality necessary to meet the requirements of cable operators. Recognizing developing converged solutions for wir
24、eless, wireline, and cable, it is expected that further development of IPCablecom 2.0 will continue to monitor and contribute to IMS developments in 3GPP, with the aim of alignment of 3GPP IMS and IPCablecom 2.0. NOTE The structure and content of this Recommendation have been organized for ease of u
25、se by those familiar with the original source material; as such, the usual style of ITU-T recommendations has not been applied. 2 References 2.1 Normative References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisio
