摘要：
A LAN signal transmission method and a transmission apparatus using the method are disclosed. A first transmission apparatus extracts only a data section of a LAN signal that is received, and accommodates the data section in a digital wrapper signal. Link information between a first LAN apparatus is accommodated in the overhead of the digital wrapper signal, and the digital wrapper signal is transmitted to a second transmission apparatus. The second transmission apparatus extracts the data section of the digital wrapper signal and the link information from the overhead of the digital wrapper signal that is received. The LAN signal that contains the data section and the link information is constituted, and transmitted to a second LAN apparatus. If the extracted link information indicates “link down”, the LAN signal to the second LAN apparatus is shut down, and the link information concerning the second LAN apparatus indicating “link down” is masked, the link information being transmitted to the first LAN apparatus.
