Abstract

A network interface apparatus is capable of bypassing an inoperable or failed network device. According to an exemplary embodiment, the network interface apparatus includes first and second transformers. A network input and a network output are respectively coupled to a first side of the first transformer and a first side of the second transformer. A terminal input and a terminal output are respectively coupled to a second side of the first transformer and a second side of the second transformer. A switch assembly is coupled to the second sides of the first and second transformers. When the switch assembly is in a first state, the second side of the first transformer is coupled to the terminal output, and when the switch assembly is in a second state, the second side of the first transformer is coupled to the first side of the second transformer bypassing the terminal output.
