| Zusammenfassung: | Provided is a mode of alarm transfer for use in a system for transmitting an encapsulated Ethernet signal between an Ethernet termination device (
110
) connected to a terminal (
100
) and an Ethernet termination device (
120
) connected to a terminal (
200
) being disposed opposite to each other. The Ethernet termination device (
110
) detects notification form the Ethernet termination device (
120
) regarding a link down between the terminal (
200
) and the Ethernet termination device (
120
), or detects occurrence of a failure on a transmission path between the Ethernet termination device (
110
) and the Ethernet termination device (
120
). When a link between the terminal (
100
) and the Ethernet termination device (
110
) is disconnected forcibly based on the detection, notification to the Ethernet termination device (
120
) regarding the link down between the terminal (
100
) and the Ethernet termination device (
110
) is withheld. |
