Abstract:
1. A call processing module, comprising: a first network interface configured to communicate over a packet-switched network; a second network interface configured to communicate with a local subscriber over a broadband access network employing radio frequency (RF) modulation to provide multiplexed programming content and an active channel map that dynamically updates a relationship of channels to services delivering the programming content carried on the channels; a call manager that includes a database associating a local subscriber telephone number with an address of a client device associated with the local subscriber for a plurality of subscribers authorized to receive telephony service; a frequency handler for dynamically allocating to the client device a receive frequency and a transmit frequency from a set of frequencies in the active channel map that are available for use for a telephony call based on the dynamically updated relationship of channels to the services delivering the programming content carried on the channels, said receive frequency and transmit frequencies being used by the client device over the broadband access network during the telephony call, wherein the frequency handler is configured to dynamically allocate the receive and transmit frequencies, modulation modes, and program IDs in the active channel map to be used by the client device; and a session manager configured to generate and receive signaling messages for establishing the telephony call between the local subscriber and a remote subscriber over the broadband access network and the packet-switched network as well as over the broadband access network and a circuit-switched network in communication with the packet-switched network.
