SYSTEMS AND METHODS FOR PROVIDING BACK POWER TO A SERVICE UNIT

摘要

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.

1. A telecommunication system comprising:
a data unit located at a customer premises, the data unit coupled to a power source; a service unit coupled to a network to receive a high-speed data stream from the network, the service unit configured to transmit data from the high-speed data stream across a drop connection to the data unit; the data unit configured to provide a direct current (DC) voltage to the service unit over the drop connection; the service unit comprising a first sensor, the first sensor configured to measure a first parameter corresponding to current used by the service unit, the service unit configured to communicate the measured first parameter to the data unit; the data unit comprising a second sensor, the second sensor configured to measure a second parameter corresponding to current provided by the data unit; and the data unit configured to determine a system condition using the first parameter and the second parameter and generate a control signal in response to determining a system condition.
