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 and ES 200 800. 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.
