［発明が解決しようとする問題点］
しかしながら従来においては、監視の対象となる周毎に
専用のモデムが監視局側に設けられるので、予備回線接
続に必要となるモデムの台数が監視対象局の数とともに
増加し、各モデムに回線を引き込むことが必要となる。[Problems to be Solved by the Invention] However, in the past, a dedicated modem was installed at the monitoring station for each cycle to be monitored, so the number of modems required for backup line connection was limited to the number of modems required for the monitoring station. As the number increases, it becomes necessary to run a line to each modem.
そして現用回線に障害が発生した監視対象局がポーリン
