An ATM signaling apparatus comprises a signaling convert section for making conversion of signaling information between an ATM network and a PBX , and a cell assembly and disassembly section (CLAD) for cell assembling and disassembling user information. An ATM signaling interface section receives and transmits ATM signaling information from/to the ATM network , and sends a user VC connect and a release indication to the CLAD section . An non-ATM signaling interface section receives and transmits PBX signaling information from/to the PBX . User information and a user information cell sent from the PBX 230 and the ATM network is cell assembled and cell disassembled by the CLAD section
