Abstract
An analog electronic circuit is placed between the central office of a telecommunications provider and the customer premises equipment of a digital subscriber line system which uses unshielded twisted pair wires ('UTP'). The electronic circuit separates the downlink signals from the uplink signals with a first mixer. The voice signals, if present, are routed around the electronic circuit unmodified. The downlink signals are amplified, filtered, amplified again with a one or more peaking equalization amplifier, then amplified with drivers which provide the power to drive the downlink signal through a second mixer onto the UTP lines to the customer premises equipment. The electronic circuit separates the uplink signals from the downlink signals with the second mixer. The uplink signals are amplified, filtered, and amplified again, then driven onto the UTP connected with the central office through the first mixer.
