Abstract To provide an interface device and the method connectable to a packet network in addition to a PSTN and an ISDN. A V5 controller 2 stores bearer channel allocation information in a control memory device 3 on the basis of control channel information which a speech path memory device 1 receives. The V5 control device 2 reads reception data of the speech path memory device 1 and the bearer channel allocation information of the control memory device 3 and gives them to a PSTN containing part 4, an ISDN containing part 4 and a packet containing part 6. Receiving transmission data, the PSTN containing part 4, the ISDN containing part 5 and the packet containing part 6 give these data to the speech path memory device 1 on the basis of the bearer channel allocation information of the control memory device 3.
