目前的一组文件规定了IPCablecom、一组协议和相关元件的功能要求。开发这些服务是为了提供服务质量（QoS）、增强的安全IP多媒体时间关键型通信服务，通过有线电视混合光纤/同轴（HFC）数据网络，使用分组数据传输技术将数据传输到消费者的家中。注1:IPCablecom文件集利用覆盖双向数据就绪有线电视网络的网络上层结构，如ES 201 488[2]和ES 200 800[3]中的规定。虽然IPCablecom产品线中的初始服务产品预计将是分组语音和分组视频，但长期来看- 长期项目愿景包括一大系列基于数据包的服务。这可能在将来不仅需要仔细的维护控制，而且还需要扩展现有文件集。注2:本套文件旨在获得全球认可和适用性。因此，它是根据其他地区和国际电信联盟（ITU）现有或正在制定的标准制定的。本文件为第9部分，涵盖网络呼叫信令（NCS）管理信息库（MIB）要求。

The present set of documents specify 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 9 and covers Network Call Signalling (NCS) Management Information Base (MIB) Requirements.
