<p>Briefly, in accordance with one embodiment of the invention, an electrical circuit comprises a voltage signal line driver (950), the voltage signal line driver (950) being characterized in that the driver includes a load termination sensing circuit (1000) adapted to measure the output current of the line driver. In accordance with another embodiment of the invention, a method of sensing a load termination at the receiving end of a telecommunications line is characterized in that the method comprises the step of measuring the output current of the voltage signal line driver (950). In accordance with yet another embodiment of the invention, a method of avoiding unstable operation by a voltage signal line driver (950) for a telecommunications line is characterized in that the method comprises the steps of: measuring the output current of the voltage signal line driver (950) during driver operation; and adjusting the open loop frequency response of the voltage signal line driver (950) substantially in accordance with the measured output current. <IMAGE></p> |
