Abstract
A network telephone device, an external connection card, and a communication method therefor are provided. The network telephone device includes a controller, a network connection port, a network transmission module and a relay. The relay is coupled between the controller and at least two of a plurality of pins of the network connection port. While an external network cable connected to the network connection port is not capable of supplying power over Ethernet (POE) or a power supply mode of the POE is a first mode of the POE, the relay connects a transmit node and a receive node of the controller to the at least two of the pins respectively. The controller and an external device connected to the external network cable transmit signals compatible with a universal asynchronous receiver/transmitter (UART) interface to transmit data or instructions with each other through the at least two of the pins of the network connection port.
