Method and Apparatus for Communicating Loss of Alternating Current Power Supply
First Claim
1. An apparatus comprising:
- a broadband communication gateway having one or more input ports to receive a direct current (DC) output signal from an alternating current (AC) to DC converter to detect a loss of an AC input signal; and
a processing unit to generate a communication message in response to receiving an interrupt signal based on the detection of the loss of the AC input signal, the processing unit to control an analog front end that sends the communication message to a device external to the broadband communication gateway in response to the interrupt signal prior to a voltage of the DC output signal decreasing below a threshold voltage needed for operation of the broadband communication gateway.

Abstract
In general, various methods, apparatuses, and systems are described for communicating a loss of an AC power source. In at least certain embodiments, a broadband communication gateway receives a direct current (DC) output signal from an alternating current (AC) to DC converter that detects a loss of an AC input signal. The apparatus further includes a processing unit that generates a communication message in response to receiving an interrupt signal based on the detection of the loss of the AC input signal. The processing unit controls an analog front end that sends the communication message to a device external to the broadband communication gateway in response to the interrupt signal prior to a voltage of the DC output signal decreasing below a threshold voltage needed for operation of the broadband communication gateway.
