Abstract
Systems and methods for increasing amplifier supply power on demand for a plurality of xDSL signals is provided. In an embodiment, circuitry may be used to detect the signal or signals having the highest voltage. In different embodiments, the signal(s) with the highest absolute voltage or highest combined voltage between complementary signal pairs may be compared to a threshold voltage, such as an existing amplifier supply voltage. In different embodiments, when these highest voltage(s) exceed the threshold voltage, the corresponding amplifier supply voltages may be increased to meet the increased amplification demand. In some embodiments when these highest voltage(s) do not exceed the threshold voltage, the amplifier supply voltage may not be increased and the existing amplifier supply voltage may be used to amplify the xDSL signals.
