Abstract
A mapping engine is configured to rearrange a configuration of data on a plurality of data channels. Each of a set of upstream filters is configured to pass one or more selected input radio frequency signals. An input of each of a set of upstream demodulators is configurable to be coupled to a selected one of the upstream filters and an output of each upstream demodulator is coupled to the mapping engine. An input of each of a set of upstream modulators is coupled to the mapping engine. An upstream aggregator comprises one or more inputs and is configured to aggregate a plurality of upstream-bound radio frequency signals, each input being configurable to be coupled to at least one selected upstream filter of the set of upstream filters and a selected upstream modulator.
