A network communication device includes a first output port, a second output port, and a converting circuit. The first output port may be in communication with an input port and may be configured to receive a first reduced-power version of the signal received at an input port. The converting circuit may be configured to receive a second reduced-power version of the signal, down-convert a high-frequency portion thereof, and produce a down-converted signal. The first and the second reduced-power versions of the signals are in the same frequency band. The second output port receives at least a portion of the down-converted signal such that the high frequency portion of the second reduced power version of the signal is attenuated before the signal is transmitted to a subscriber device.
