Abstract

A programmable access point (110) has a line driver (201), sensors (202), comparator and control logic (203), a power supply (206), and a backup power supply (207). The line driver (201) provides power and communications signals to attached customer equipment and receives its power from either power supply (206, 207). The power supplies generate status signals indicating whether the line driver (201) is receiving power from the power supply (206) or the backup power supply (207) and indicating the reserve capacity of the backup power supply (207). The sensors (202) monitor the power output by the line driver (201). The comparator and control logic (203) receives the power supply status signals and the monitored power output values and generates a control value that is provided to the line driver (201), which modifies its output in response.
