Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Access and Terminal

18、s (AT). The present document is part 24 of a multi-part deliverable covering Digital Broadband Cable Access to the Public Telecommunications Network; IP Multimedia Time Critical Services. Full details of the entire series can be found in part 1 1. The present document describes the ISDN-enabled Mult

19、imedia Terminal Adapter (iMTA) architecture and protocols for Internet Protocol (IP)-based Cable Telephony ISDN services. Introduction The cable industry in Europe and across other global regions has already deployed broadband cable television Hybrid Fiber/Coaxial (HFC) data networks running the int

20、ernational cable modem protocol (a.k.a DOCSIS, see bibliography) or the European adaptation thereof (a.k.a Euro-DOCSIS, see bibliography). The cable industry is in the rapid stages of deploying IP voice and other time critical multimedia services over these broadband cable television networks. The c

21、able industry has recognized the urgent need to develop ETSI Technical Specifications aimed at developing interoperable interface specifications and mechanisms for the delivery of end to end advanced real time IP multimedia time critical services over bi-directional broadband cable networks. IPCable

22、com is a set of protocols and associated element functional requirements developed to deliver Quality of Service (QoS) enhanced secure IP multimedia time critical communications services using packetized data transmission technology to a consumers home over the broadband cable television Hybrid Fibr

23、e/Coaxial (HFC) data network running the cable modem protocol. IPCablecom utilizes a network superstructure that overlays the two-way data-ready cable television network. While the initial service offerings in the IPCablecom product line are anticipated to be packet voice, the long-term project visi

24、on encompasses packet video and a large family of other packet-based services. The cable industry is a global market and therefore the ETSI standards are developed to align with standards either already developed or under development in other regions. The ETSI Specifications are consistent with the

25、CableLabs/PacketCable set of specifications (see bibliography) as published by the SCTE (see bibliography). An agreement has been established between ETSI and SCTE in the US to ensure, where appropriate, that the release of PacketCable (see bibliography) and IPCablecom set of specifications are alig

26、ned and to avoid unnecessary duplication. The set of IPCablecom ETSI specifications also refers to ITU-T Study Group 9 draft and published recommendations relating to IP cable communication. The initial effort in IPCablecom has been on supporting analogue, POTS MTA terminals through IPAT V5.2 gatewa

27、y interfaces (see TS 101 909-23, see bibliography) to support IP Voice (Telephony over IP) and other time critical multimedia services over these broadband networks. However, a need has been identified in TR 101 963 8 (see clauses 5.3 and 9) to support also legacy ISDN terminal equipment in the wide

28、r European market. Consequently in order to support the development of broadband networks and equipment with support for legacy ISDN terminals, the key functions and features of these ISDN-capable MTAs need to be sufficiently defined. ETSI ETSI TS 101 909-24 V1.1.1 (2004-05) 6 The whole set of multi

29、-part ETSI deliverables to which the present document belongs specify a cable communication Service for the delivery of IP multimedia time critical services over a HFC Broadband Cable Network to the consumers home cable telecom terminal. “IPCablecom“ also refers to the ETSI TC AT working group progr

30、am that shall define and develop these ETSI deliverables. NOTE: The present document may have impacts upon other deliverables of the ETSI multi-part IPCablecom series; such potential impacts are currently unknown and are for further study. Thus, a need may arise in the future to revise the present d

31、ocument accordingly. ETSI ETSI TS 101 909-24 V1.1.1 (2004-05) 7 1 Scope The present set of documents specifies IPCablecom, a set of protocols and associated element functional requirements. These have been developed to deliver Quality of Service (QoS), enhanced secure IP multimedia time critical com

32、munication services, using packetized data transmission technology to a consumers home over a cable television Hybrid Fiber/Coaxial (HFC) data network. To facilitate maintenance and future enhancements to support other real-time multimedia services the TS 101 909 document series consist of multi-par

33、ts as detailed in TS 101 909-1 1. The present document is part 24 providing a technical description of this architecture, and where appropriate, identify the portions of the IPCablecom specifications that apply to this architecture and their use. The embedded, ISDN-enabled MTA (iMTA) and its interfa

34、ces are described in the present document. The definition and interfaces of a standalone ISDN MTA (S-iMTA) are not described in the present document and remain as for further study. While the initial service offerings in the IPCablecom product line are anticipated to be packet voice and packet video

35、, the long-term project vision encompasses a large family of packet-based services. This may require in the future, not only careful maintenance control, but also an extension of the present set of documents. The present document assumes familiarity with the IPCablecom architecture, specifically wit

36、h DQoS, security and call signalling. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
