ABSTRACT:
When a malfunction of a master connection100is detected by an ATM exchanger, etc., a notice thereof is transmitted to an NMS40. The NMS40is at all times kept monitoring the state within the network. When receiving the notice of the malfunction from the ATM exchanger, the NMS40operates on respective cell header translators (HT)1B,1C,3B, and3C that are associated with the master connection100that has malfunctioned. And, the NMS40changes the set values of the cell header translators according to the notice of the malfunction. As a result, the ATM cell is bypassed to a bypass connection200.
