Abstract
In a communication system including an external maintenance terminal and a communication device in which boards including a maintenance-and-operation board and a switchboard are installed, the switchboard is directly connected to the external maintenance terminal, and a predetermined address is assigned for use only in communication between the maintenance-and-operation board and the external maintenance terminal, and set in the switchboard. When communication is performed between ones of the boards, the switchboard connects the ones of the boards on the basis of the local addresses of the ones of the boards. When communication is performed between the maintenance-and-operation board and the external maintenance terminal, the switchboard connects the maintenance-and-operation board to the external maintenance terminal, and translates a global address of the external maintenance terminal into the predetermined address and vice versa.
