Abstract

A combination of algorithms and circuits are used to combine POTS, high-speed bi-directional data, and back-powering onto the drop connection for fiber to the distribution point architectures. A telephone adapter device can be utilized to prevent damage from back-powering occurring at POTS telephones connected to the drop connection. In addition, circuits are used to prevent damage from back-powering occurring at POTS telephones directly connected to the drop connection. A circuit is used to provide more consistent power to the electronics at the distribution point even when the input back-power to the distribution point may fluctuate.
