摘要： A communication network capable of establishing an SVC bypass route when a failure occurs in a PVC multiplexed line wherein each of ATM switches at both ends of a PVC stores the relations of SVC specifying information and the other party PVC information in association with each PVC in a management table. At the time of bypassing, one of the switches transmits a message including the other party PVC information to another ATM switch for each PVC to be bypassed and another ATM switch specifies a PVC to be switched on the basis of the received message and switches the PVC to an SVC specified by the corresponding SVC specifying information stored in the management table.

摘要： In an ATM network having a non-ATM apparatus such as a PBX, a band and various apparatuses are effectively used by employing SVC, so that a ring back tone, etc., is transmitted to the non-ATM apparatus of originating side. An ATM signaling apparatus 210 comprises a signaling convert section 201 for making conversion of signaling information between an ATM network 220 and a PBX 230, and a cell assembly and disassembly section (CLAD) 204 for cell assembling and disassembling user information. An ATM signaling interface section 203 receives and transmits ATM signaling information from/to the ATM network 220, and sends a user VC connect and a release indication 209 to the CLAD section 204. An non-ATM signaling interface section 202 receives and transmits PBX signaling information from/to the PBX 230. User information 206 and a user information cell 208 sent from the PBX 230 and the ATM network 220 is cell assembled and cell disassembled by the CLAD section 204.
