Abstract
An apparatus and method to automatically adjust a gain of an analog signal adapted to be transmitted over a twisted pair of telephone lines between a first end (e.g., a DSLAM), and a second end (e.g., a modem), is described. The apparatus comprises an amplifier, and a control mechanism. The amplifier receives the analog signal from a respective first or second end, and transmits the received analog signal in the respective downstream or upstream direction. The control mechanism, which preferably is operative only during a train or re-train mode, senses whether the analog signal is within a specified amplitude range associated with a receiver at the respective second end or first end, and, responsive to a determination that the analog signal is not within the specified amplitude range, determines and generates a control signal. The control signal is operative to adjust a gain of the amplifier to a determined value.
