Abstract
A system and method for switching between voice signals. The system includes a network interface device and a digital logic device. The network interface device may include a splitter and a switch. The splitter includes a network input configured to receive a combined voice and digital signal. The splitter generates a separate first voice output and a digital signal. The first voice signal is provided from the splitter to the switch, while the digital signal is provided to the digital logic device. The digital logic device is configured to generate a second voice signal that is also provided to the switch. Further, the digital logic device provides a control signal to the switch. The control signal manipulates the switch to selectively provide either the first or second voice signal to a voice output.
