Burst-mode combining of reverse path radio frequency signals

This invention relates generally to broadband communications systems, such as cable television systems, and more specifically to burst-mode combining of reverse path radio frequency (RF) signals that are generated in the broadband communications systems. The present invention is directed towards a burst-mode combiner (BMC) typically located within a headend facility for transmitting received reverse signals to a specific application device dependent upon the presence of a carrier signal. The BMC includes BMC circuits that are each coupled to reverse receivers. The BMC circuits filter the reverse signals into specific frequencies. A carrier detect circuit detects the presence of a carrier signal, and when detected, allows the delayed reverse signals to be transmitted through to the application device.
