The system and manner in order after the repairing the breakdown to reconstruct telecom network in the normal state

摘要

(57) Abstract After the link (34) which breaks down was repaired, in order to return toboroji of network to the first state, operation support system (OSS) (22), command of each one which returns to the operation which the management node (4 and 8) and the tandem node (14, 16 and 18) which form the alternative root respectively, each node ran while rehabilitating is sent. OSS (22) identifies due to the fact that these nodes many operations compared to the tandem node (14, 16 and 18) run the management node (4 and 8). The operation which was run while rehabilitating was recorded. When the fact that is received, link (34) of breakdown was repaired from the node which differs, OSS (22) sends the command of the specification which runs the operation of converse of the operation which the node (4, 8, 14, 16 and 18) respectively, the node ran while rehabilitating. The management node (4 and 8) that the operation of those converse is run in the beginning, is instructed, as a result, as for the link (34) which was repaired for the second time, joints the management node (4 and 8). Integrity of the link (34) where next, pass verification process was run, was repaired is made secure.
