The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operat
5、ing 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 turn, pro
6、duce 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 In th

16、supporting the IPCablecom2 Residential SIP Telephony (RST) application. The IPCablecom2 architecture provides a generic Provisioning Framework for E-UEs, but requires IPCablecom2 application efforts such as RST to specify application-specific requirements and data models. This Recommendation specifi
17、es such requirements and the data model for the IPCablecom2 RST application. It also specifies the requirements and a data model for E-DVAs, a specific E-UE type specified by IPCablecom2. It is an important objective of this work that interoperability between IPCablecom 2.0 and 3GPP IMS is provided.
18、 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 wireless, wireline, and cable, it is expected that further development of IPCablecom 2.0 will continue to monitor and co
19、ntribute to IMS developments in 3GPP, with the aim of alignment of 3GPP IMS and IPCablecom 2.0.

The IPCablecom2 architecture describes a set of functional groups and logical entities, as well as a set of interfaces that support the
38、 information flows exchanged between entities. For more information about IPCablecom2, please refer to the IPCablecom2 Architecture Framework Technical Report ARCH-FRM. As part of these efforts, IPCablecom2 specifies applications built upon the IPCablecom architecture. One such application is RST. T
39、his Recommendation describes the configuration and management requirements applicable to Embedded User Equipment (E-UE) supporting the RST application. Within the context of this Recommendation, any reference to an E-UE (or eUE) needs to be interpreted as an E-UE (or eUE) that supports the RST appli
40、cation, sometimes referred to as an RST E-UE. For more information on the RST application, please refer to RSTF. Specifically, this Recommendation covers the following areas: Configuration and Management requirements for E-UEs supporting RST, including E-DVA specific requirements, The RST Applicatio
41、n Data Model, The E-DVA Data Model for Configuration and Management. 5.1 Residential SIP Telephony The IPCablecom2 RST Feature specification specifies an implementation of common residential telephony features in an IPCablecom network, including, but not limited to: called ID, call 4 Rec. ITU-T J.46
42、0.4 (06/2008) forwarding, hold, transfer, three-way calling, emergency calling, and operator service. For more information, please refer to RSTF. 5.2 E-UE Provisioning Framework The IPCablecom2 E-UE Provisioning Framework Specification EUE-PROV, together with the E-UE Provisioning Data Models Specif
43、ication EUE-DATA, specifies interfaces, protocols, and data models to support configuration and management of E-UEs in an IPCablecom network. Those documents require IPCablecom application specifications, such as RST, to utilize these interfaces and extend the data models as required to support the
44、specified features. 5.3 RST E-UE The E-UE, by definition, is an embedded IPCablecom2 device, as specified in EUE-PROV. The RST E-UE is an E-UE that supports the IPCablecom2 RST application. RST E-UEs require RST specific data to be configured, and have additional requirements, as specified in this R
45、ecommendation. 6 IPCablecom RST E-UE Architecture and Requirements This clause presents the normative requirements for RST E-UE Provisioning, using the IPCablecom E-UE Provisioning Framework. It includes references to the framework, and any necessary enhancements to support the RST application. For
46、more information on IPCablecom E-UE Provisioning Framework please refer to EUE-PROV. The E-UE consists of two components: the eCM and the eUE. For more information on the eCM configuration and management requirements for IPCablecom, please refer to EUE-PROV. The eUE Provisioning Framework Architectu
47、re, based on the Provisioning Framework is specified in Clause 6.1. The component requirements and other enhancements are listed in the following sub-clauses. 6.1 eUE Provisioning Framework Architecture Figure 1 represents the network components and interfaces that form the eUE Provisioning Framewor
