Abstract
A method of channel-to-port assignment is described where the distribution of channels is performed in the digital domain of the CATV/QAM upconverter/modulator. This channel distribution allows for the possibility of simple failover, power combining of multiple outputs, and a fine granularity of channel to port mapping, QAM or analog channel, in a multi-port device.
