Abstract
A return path system includes inserting RF packets between regular upstream data packets, where the data packets are generated by communication devices such as a computer or interne telephone. The RF packets can be derived from analog RF signals that are produced by legacy video service terminals. In this way, the present invention can provide an RF return path for legacy terminals that shares a return path for regular data packets in an optical network architecture.
