Abstract
A gateway enables mutual data communication between two or more networks by connecting the networks and forming a bypass path between the two networks to enable data communication therebetween when the gateway does not support a normal data communication mode. The gateway can form at least one physical communication path between the networks through the gateway even if the gateway cannot support a normal communication mode and/or power is interrupted to the gateway. Further, in spite of abnormal conditions, such as abnormal power supply to the gateway, if the bypass path is not formed, a user can compulsorily form the bypass path, thus improving reliability of a network system.
