ABSTRACT:
A communication device for exchanging communication between user devices and a communication network reduces power consumption after detecting a low power condition. The communication device advantageously operates during a power outage when a power supply for the communication device fails. The communication device includes a network interface, a power control circuitry, and a processor. The network interface exchanges digital communication signals with the communication network. The power control circuitry detects a low power condition. The power control circuitry then generates a power control signal in response to the low power condition. The processor exchanges first communication signals between the network interface and an analog telephone interface or a digital computer interface. The processor receives and processes the power control signal to lower power consumption of the communication device.
