Abstract:
1. An application specific integrated circuit (ASIC), comprising: a control logic to provide a control signal to control how a cable modem terminal system (CMTS) combines and splits signals received from radio frequency modules and physical interface modules; a multiplex logic to selectively combine at least two pre-multiplex signals into at least one post-multiplex signal based, at least in part, on the control signal, where a pre-multiplex signal is received from one of, a radio frequency module (RFM) in the CMTS and a physical interface module (PHYM) in the CMTS, and where a post-multiplex signal is provided to one of, a RFM in the CMTS and a PHYM in the CMTS; and a demultiplex logic to selectively split at least one pre-demultiplex signal into at least two post-demultiplex signals based, at least in part, on the control signal, where a pre-demultiplex signal is received from one of, a RFM in the CMTS and a PHYM in the CMTS, and where a post-demultiplex signal is provided to one of, a RFM in the CMTS and a PHYM in the CMTS; where the multiplex logic operates in one of, a static multiplexing mode and a dynamic multiplexing mode; where the control logic controls the multiplex logic to dynamically change the at least two pre-multiplex signals to selectively combine on a per burst basis in the dynamic multiplexing mode.
