ATM EXCHANGE, ATM EXCHANGE SYSTEM, SVC CONNECTION BYPASS CONTROL METHOD AND STORAGE MEDIUM STORING SVC CONNECTION BYPASS CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To obtain an ATM exchange or the like that has a fault restoring function of an SVC connection. ;SOLUTION: Occurrence of a fault path due to a fault is monitored and the fault path 9 is released in the case of detecting the fault path. In the case that the fault path 9 is a node device of a caller terminal 1, a called address is used to make routing and to set a substitute path 10. In the case of an incoming call received again, an information element of a message is compared with an information element of an existing SVC connection. By judging to be a same SVC connection, whether or not a path is a substitute path corresponding to a block of the fault path is discriminated, the presence of the block of the fault path is judged, a path on an interface toward the fault path block is released and a substitute path 10 receiving an incoming call again and a path of a called terminal 2 are managed as one connection. Then the ATM exchange detecting a fault makes redialing to set up a substitute path block in place of the fault path block between the ATM exchanges.;COPYRIGHT: (C)2000,JPO
