Abstract
An Ethernet protection system includes an Ethernet communication device operable to be connected to first and second Ethernet lines forming a parallel connection. The Ethernet communication device is able to select the first Ethernet line and transmit and receive data over the first Ethernet line, and upon detecting a failure in the first Ethernet line, automatically select the second Ethernet line and transmit and receive data over the second Ethernet line.
