ABSTRACT:
A network system includes a local area network to which a plurality of transmission apparatuses are connected, a gateway apparatus for connecting the local area network to a wide area network, and a plurlaity of terminal adapters for connecting the local area network to communication terminal apparatuses, and a management method therefor. Each transmission apparatus sends a transmission request of management data requesting data on the operating conditions of the connected local area network, the gateway apparatus, and the terminal adapters, acquires data on the operating conditions of the other apparatuses sent in response to the transmission request, and simultaneously displays the acquired management data, so that the operating conditions of the apparatuses connected to the system can always be monitored. Even when a communication error occurs, location of the source of the error can be easily determined without arranging a special-purpose LAN monitoring apparatus.
