Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Services and Protocols for Advanced Networks (SPAN). The present document describes the requirements
38、 used in the design and specification of the general architecture, the IPCablecom Signalling Transport Protocol (ISTP), and the Trunking Gateway Control Protocol of the ITU IPCablecom set of specifications. The requirements listed in the present document have been obtained by reverse engineering of
39、the specific ITU Recommendations, i.e. J.istp or ITU-T RecommendationJ. 165 2 for the IPCablecom Signalling Transfer Protocol, J.arch or ITU-T Recommendation J.160 i for the architectural framework, and J.tgcp or ITU-T Recommendation J.171 3 for the Tninkng Gateway Control Protocol. ETSI 9 ETSI TR 1
40、02 O19 VI .I .I (2002-02) 1 Scope The present document specifies the design and specification requirements obtained from reverse engineering a set of ITU recommendations, consisting of J. arch (architectural framework), J.istp (IPCablecom Signalling Transfer Protocol), and J.tgcp (Tninkng Gateway Co
41、ntrol Protocol). These documents are part of a set of ITU documents describing the IPCablecom framework and its subparts. These documents are based on the Packetcable 1 .O specifications written by CableLabs in the United States, and modified to meet more global requirements and formatting conventio
42、ns of the ITU. The requirements obtained from reversed the specified documents can be explicitly listed or implied, commercial or technical. The present document does not contain all of the IPCablecom requirements, which cover a set of documents addressing additional areas of quality of service, sec
43、urity, lawful intercept, network interface, remote digital thermals, on network call singling, managed object provisioning, event messaging, and other major areas. Some operator requirements (example: billing, OSS presentation, etc.) are deliberately not covered in IPCablecom; these are considered n
44、ormal to vendor/operation (RFQ/RFI) negotiations to meet subscriber needs in a market. These operational requirements are not covered here except where they are defiied in the source documentation. In the present document, all requirements have been presented with “MUST“, “SHALL“, “SHOULD“, or “MAY“
45、 as the active verb. “It“ in the present document when coupled to a requirement refers to IPCablecom in general. In particular, must and must no were used instead of shall or shall not to spec requirements, should or should not were used to spec recommendations, may or may not were used to spec perm
46、issions or possibilities, and can or can not were not used to spec possibly. The present document contains the original requirements as created for the Packetcable 1 .O specifications (written by CableLabs in the United States). These base requirements can be realized by using other protocol stacks
47、and are not restricted to those specified in the present document. The base requirements that are implied by the protocols should be included in any protocol implementation. 2 Re fe re nces For the purposes of this Technical Report (TR) the following references apply: il ITU-T Recommendation J. 160
