Abstract
The present multi-media communication subscriber station has battery-powered backup. A power management controller monitors the line voltage and when the line voltage falls below a predetermined voltage level, the power management controller transfers operation power from line voltage to battery. When the multi-media communication subscriber station is operating on backup battery power, non-essential functional modules may be disabled. The power management controller continues to monitor the line voltage and when line voltage resumes, operation power is transferred back to line voltage.
