Abstract
A processor controlled mechanism automatically determines from a location such as a central office whether termination equipment installed at a remote end of a wireline link is span-powered, or is powered locally. It then applies a voltage to the wireline link that is appropriate for the identified type of termination equipment. This eliminates the need for two separate central office loop-powering devices. In the course of making the determination, nothing higher than a safety extra low voltage is applied to the wireline link, to comply with Underwriter's Laboratory standards for locally powered customer premises equipment.
