Title:
FAULT DISCRIMINATION SYSTEM FOR MULTI ROUTE STRUCTURE NETWORK
Document Type and Number:
Japanese Patent JP3036989
Kind Code:
B2
Abstract:
PURPOSE: To manage the operation state of the multi route/multi system network in more real time by connecting a terminal system, the path of a transmission line network, and the path of an exchange network.
CONSTITUTION: When a fault is generated in a transmission line path a1, the routes AB1 and AC1 are affected by the link information of the path a1 and stopped. Further, when an exchange 4 detects the stop of all exchange routes (2 → 4.2 → 4 →7) to be connected with an exchange 2 as a discrimination result, the AB2 route is stopped from the link information. The down detection of the exchange route 2 → 4 → 7 is caused by the stop of the exchanges 2 and 4 themselves, or by the fault of the all paths between the exchanges 4-7, or by the all paths between the exchanges 2-7. At this point, the all routes controlled by the multi route are stopped, the down of the multi route is discriminated, and the emergency report is transmitted to the operator of a network.
