[0006]

However, in the prior art described in Japanese Patent Application Laid-Open No. H11-112694, first, call setup is performed on ISDN.
After confirming that the channel is blocked, the relay physically disconnects the DSU from the terminal, and then waits for a predetermined time before calling the report destination. There was a problem that it took time from the occurrence of the situation to the start of the report.

Further, in the conventional technique described in Japanese Patent Application Laid-Open No. H10-285300, since two DSUs are used, there is a problem that the cost required for introducing a notification device increases.

The present invention has been made in order to solve such a problem. Even when a terminal device is communicating and there is no available channel, it is possible to promptly report when an emergency occurs. The purpose of the present invention is to provide a reporting device capable of performing the above.
