本套文件规定了IPCablecom、一套协议和相关元件的功能要求。 这些都是为了提供服务质量（QoS），增强安全的IP多媒体时间关键 通信服务，使用分组数据传输技术通过有线电视传输到消费者家中 混合光纤/同轴（HFC）数据网络。注1:IPCablecom文档集利用覆盖双向数据就绪电缆的网络上层结构 电视网络，如ES 201 488[2]和ES 200 800[3]中的规定。虽然IPCablecom产品线的初始服务产品预计为分组语音和分组视频， 长期项目愿景包括一大系列基于数据包的服务。这可能需要在未来，而不是未来 不仅要小心维护控制，还要扩展现有的一套文件。注2:本套文件旨在获得全球认可和适用性。因此，它是在 与其他地区和地区已经存在或正在制定的标准保持一致 国际电信联盟（ITU）。本文件是上述ETSI可交付成果系列的第1部分，具体说明了 IPCablecom基于J.16x和J.17x ITU-T系列建议。

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 communication services, using packetized data transmission technology to a consumer's home over a cable television Hybrid Fibre/Coaxial (HFC) data network.NOTE 1: IPCablecom set of documents utilize a network superstructure that overlays the two-way data-ready cable television network, e.g. as specified within ES 201 488 [2] and ES 200 800 [3].While the initial service offerings in the IPCablecom product line are anticipated to be Packet Voice and Packet Video, 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.NOTE 2: The present set of documents aims for global acceptance and applicability. It is therefore developed in alignment with standards either already existing or under development in other regions and in International Telecommunications Union (ITU).The present document is part 1 of the above mentioned series of ETSI deliverables and specifies general aspects of IPCablecom based on J.16x and J.17x ITU-T series of Recommendations.
