Describes generic preferred methods for the traffic control and dimensioning of IP-access networks based on hybrid fiber/coax (HFC) system, taking into account the capabilities and limitations of the cable-modem based access technology. Focuses on the provision over HFC system of IP telephony service in an integrated voice/data environment. Describes factors affecting system capacity for the support of voice connections.
