Abstract: Systems and methods are provided for utilizing low gain low noise signal amplification and ideal taps in coaxial networks. An ideal tap configured for use in coaxial networks may have a plurality of ports, one or more processing circuits configured for handling reception and transmission of signals communicated via the tap, and one or more echo cancellation circuits configured for providing echo cancellation during operations of the tap. The processing circuits are configured based on particular predefined tap performance criteria. The tap performance criteria may relate to one or more of port-to-port isolation, return loss, port-to-port gain, and up-tilt. The echo cancellation circuits may be configurable for providing the echo cancellation based on the tap performance criteria. The echo cancellation circuits may include an echo cancellation control circuit for controlling echo cancellation functions and/or operations. The echo cancellation circuits may include dedicated per-port echo cancellation circuits.

Abstract: An ideal tap may have a plurality of ports that include at least an input port configured for receiving downstream (DS) signals from and transmitting upstream (US) signals to nodes upstream from the tap within the coaxial network, and one or more other ports that comprise at least one of an output port configured for transmitting downstream (DS) signals to and receiving upstream (US) signals from nodes downstream from the tap within the coaxial network, and a drop port for receiving signal from and transmitting signals to customer premise equipment (CPE) in the coaxial network. The ideal tap may further include processing circuits for handling signals received and transmitted via the tap, with the one or more processing circuits being configured to meet particular predefined tap performance criteria, and to specifically apply, during handling of signals in the tap, frequency shifting based on one or more frequency spectrum shift conditions.
