ABSTRACT:
A method of establishing a transmission power level for signals transmitted in a conductor is provided in an environment where signal interference is present between the signals in the conductor and separate signals carried in a proximate conductor. The method includes the steps of determining a reference signal interference level at an end of the proximate conductor from a reference signal capable of being propagated from an opposing end of the proximate conductor and determining a transmission power level for the signals to provide a signal interference level based on the reference signal interference level. A system embodying the method is also provided.
