ABSTRACT:
Inter-LAN connection using an ISDN, in which two LANs are connected to each other by an inter-LAN connection apparatus through the ISDN, includes using, as the ISDN, an INS net 64, for example, for providing at least two B channels and one D channel. The inter-LAN connection apparatus has a section for setting a circuit switching mode in a first B channel, of the B channels and the D channel, assigned as a data transfer channel and setting a packet switching mode in a second B channel, of the B channels and the D channel, assigned as a control information transfer channel to perform circuit connection when data communication must be performed while dynamic routing is performed.
