  • Patent number: 8032640
    Abstract: The invention provides a PVC switching control method for an ATM communication network which allows high speed changeover of a connection upon occurrence of/release from a trouble and is superior in reliability and maintenance facility and simple in control. A master PVC connection and an OAM connection are set between two ATM exchanges, and a bypassing PVC connection and an OAM connection prepared in advance for bypassing are set between the two ATM exchanges. If occurrence of/release from a trouble with and of the master PVC connection is recognized by the ATM exchanges using an OAM function, then the operative PVC connection is switched between the master PVC connection and the bypassing PVC connection.

  • Patent number: 6944124
    Abstract: When a malfunction of a master connection 100 is detected by an ATM exchanger, etc., a notice thereof is transmitted to an NMS 40. The NMS 40 is at all times kept monitoring the state within the network. When receiving the notice of the malfunction from the ATM exchanger, the NMS 40 operates on respective cell header translators (HT) 1B, 1C, 3B, and 3C that are associated with the master connection 100 that has malfunctioned. And, the NMS 40 changes 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 connection 200.
