Abstract

PURPOSE:To prevent a packet exchange data from being outputted to a line exchange function control section by allowing a packet exchange function control section to detect it if a fault takes place in the line exchange function control section in a node station takes place and its operation is stopped. CONSTITUTION:An operation status display signal 401 is outputted at a constant interval from a line exchange function control section 303. If any fault takes place in the section 303, however, the operation status display signal 401 is not correctly outputted. If the signal is not received for a prescribed time or over, a packet exchange function control section 306 regards it that the line exchange function control section 303 causes abnormality or operation stop to stop an output of a packet exchange data to the line exchange function control section 303. Since a packet exchange data is not outputted to a faulty line exchange function control section in this way, even if the line exchange function control section is disconnected from the network, the abort of the packet exchange data is prevented.
