Abstract

PURPOSE:To diagnose the system of an extended station without interrupting the working of a LAN system by transferring a diagnosing frame produced newly at the side of the extended station to an existing station for execution of the LAN system. CONSTITUTION:When a new station is extended to a LAN, a diagnosising frame containing the diagnosing identification information on the addresses of its own station and the remote side station is sent to an existing station from the extended station 1. The existing station decides the presence or absence of the diagnosing frame based on the identification information. When the diagnosing frame is confirmed, the corresponding frame is sent back to the station 1 from the existing station. The station 1 recognizes the received frame and performs the diagnosis of a system. Thus it is possible to perform the diagnoses of a coaxial cable 3, a transceiver 4, a transceiver cable 5, etc., without stopping the working of a LAN system even in case a new station is added to the working LAN system.
