PacketCable defines a network superstructure that overlays the two-way dataready broadband cable DOCSIS 1.1 access network. PacketCable specifications define how PacketCable elements interact with each other and the protocols that are used between these elements. Since PacketCable certification/qualification only includes the protocol compliance of these elements, the certification/qualification does not suffice as the necessary means to provide a competitive service as provided by today’s Public Switched Telephony Network. This paper details some of the features that are necessary for competitive telephony service. Some of these features are not covered by PacketCable certification/qualification tests.
