Abstract:
1. A cable communication system to provide voice and/or data services to a plurality of subscriber premises, the system comprising: a cable plant to convey at least upstream information from the plurality of subscriber premises in at least a first neighborhood node of the cable communication system over an upstream path bandwidth assigned to the first neighborhood node, the upstream information being conveyed on the cable plant via a plurality of upstream radio frequency (RF) signals from the first neighborhood node, each upstream RF signal of the plurality of upstream RF signals including an encoded carrier wave having a carrier frequency in the upstream path bandwidth assigned to the first neighborhood node and being modulated, using quadrature amplitude modulation (QAM), with voice and/or data information constituting at least some of the upstream information from at least some of the plurality of subscriber premises, wherein: the plurality of upstream RF signals includes a first upstream RF signal having a first carrier frequency of greater than or equal to approximately 5 MHz, and less than or equal to approximately 16.4 MHz; the first upstream RF signal defines a first upstream physical communication channel in the upstream path bandwidth; the first upstream RF signal is encoded with at least some of the voice and/or data information using a Time Division Multiple Access (TDMA) protocol or an Advanced Time Division Multiple Access (ATDMA) protocol; and an aggregate deployed upstream capacity of the plurality of upstream RF signals to convey, in a portion of the upstream path bandwidth between 5 MHz and 16.4 MHz, the at least some of the upstream information from the at least some of the plurality of subscriber premises in the first neighborhood node is at least approximately 12 Megabits per second (Mbits/s).
