<p>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.</p> |
