Abstract
A transmission apparatus includes a processor that is operative to terminate a first line performing a communication using a digital wrapper, to terminate a signal on a second line performing a communication using Gigabit Ethernet, to apply a transparent transcoding process to a terminated signal and the signal received from the second line and to output these signals; and wherein when a fault occurs in a communication performed through the first line and when there is no response for a predetermined time period after an auto negotiation restart signal is reported to an opposite apparatus on a second line side, to report information indicating an occurrence of the fault to the opposite apparatus by using a signal of a MAC (Media Access Control) frame format.
