Abstract
Only one ATM call setting path is set between two ATM-WAN nodes, and ATM communication paths for audio signals of a number corresponding to the number of calls are set. If call setting N-ISDN signals are transmitted from a PBX-A, the IWF of the ATM-WAN nodes on a calling party side stores the call setting N-ISDN signals in ATM cells transparently as they are, and sends the ATM cells to a common ATM call setting path. If call setting channel associated signals are transmitted from a PBX-B, the IWF of the ATM-WAN nodes on a calling party side converts the call setting channel associated signals to call setting N-ISDN signals, stores the converted signals in ATM cells, and sends the ATM cells to a common ATM call setting path.
