When the state in said service layer path is normal condition, confirm that last state is disconnected node TP1 fault point on the said client trail.

27. method according to claim 26 is characterized in that, said method also comprises:

When the state in said service layer path is malfunction; If said service layer path is not a bottom; Then detect the state of each node on the said service layer path, last state on the said service layer path sought is disconnected node TP2, and detects the state in the following one deck service layer path before the said TP2; If said service layer path is a bottom, then last state on the said service layer path is confirmed as the fault point for disconnected node TP2.

28. the localization of fault device of a wave division path is characterized in that said device detects according to the order from the destination node to the source node, said device comprises:

First detecting unit is used to detect the state of client trail;

Second detecting unit; Be used for when the state of said client trail is malfunction; If said client layer is a bottom, then detect the state of each node on the said client trail, confirm that last state is the fault point for disconnected node; If said client layer is not a bottom, then detect the state in the corresponding service layer path of said client trail;

The 3rd detecting unit is used for when the state in said service layer path is normal condition, detecting the state of each node on the said client trail, and last state on the said client trail is confirmed as the fault point for disconnected node.

29. the localization of fault device of a wave division path is characterized in that, said device is according to detecting from destination node to the source node order, and said device comprises:
