Abstract:
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 wherein the communication message generated in response to the processing unit receiving the interrupt signal is based on the loss of the AC input signal and indicates to at least one of a communications service provider and a communications maintenance provider a disconnect condition between the broadband communication gateway and an external device coupled over a telephone network to the broadband communication gateway.
