Abstract
A Line Interface Unit (LIU) can communicate a number of electromagnetic waveforms consistently fitting into a variety of specific waveform masks, such as masks defined by ITU-T G.703. The LIU includes a transmit part that includes a feedback controller that facilitates the LIU outputting electromagnetic waveforms consistently fitting into the specific waveform masks. The feedback controller can compensate for changes in environmental conditions, such as supply voltage, line profile, line impedance per protocol, doping gradient, and temperature. Also, this feedback controller allows for avoiding constant hardware modifications to the LIU for adjusting to different protocols or masks. It also can enable the LIU to instantiate a great number of times, such as twenty-one times on the same die, where the transmit part performs the feedback controller independently for each instantiation.
