Abstract: The present invention relates to a signal transmission system for inserting a communication signal within an upstream and downstream signal. An upstream converter inserts the communication signal within a diplex guard band of the upstream and downstream signal. A downstream converter separates the communication signal within the diplex guard band from the upstream and downstream signal.
