<p>In a LAN interconnecting apparatus having two transmitting and receiving sections (11a, 12a; 11b, 12b) connected to respective LANS (1a; 1b), each of the transmitting and receiving sections can be set in either a first or a second operation mode by setting a register (121a; 121b). The transmitting and receiving section copies and transfers relayed information frames in the first operation mode, but has not these functions in the second operation mode. The apparatus makes a unidirectional LAN -interconnecting apparatus when one of the transmitting and receiving sections is set in the first operation mode and the other in the second operation mode, while it makes a bidirectional one when both of the transmitting and receiving sections are set in the first operation mode.</p> |
