ABSTRACT:
A terminal device management system includes a plurality of terminal devices and a remote management apparatus for remotely managing the plurality of terminal devices. The remote management apparatus includes a data receiving section, a management table storing section for storing a management table including identifiers for the terminal devices which are set to transmit data in a transmission time interval for identifying whether data has been Bent from the terminal devices or not, a timer section for measuring a time period during which a line is not connected in the transmission time interval, and a control section for detecting whether or not the time period measured by the timer section reaches a predetermined time period, and for, when it is detected that the predetermined time period is reached, detecting a terminal device the identifier of which in the management table stored in the management table storing section indicates data has not been received therefrom, as a failed terminal device.
