<p>A terminal system containing a plurality of terminal apparatuses (9, 106) which are connected through a two-way bus line to a communication network. Each of the plurality of terminal apparatuses (9, 106) comprises: an incoming call detecting unit (28, 17) for detecting an incoming call to which the terminal apparatus can respond, where the incoming call detecting unit belongs to the terminal apparatus; and a responding unit (23, 12, 18) for responding to an incoming call which is detected in the incoming call detecting unit (28, 17), where the responding unit (23, 12, 18) has a response time which is needed to respond to the incoming call, and is intrinsic to each term nal apparatus. Each of the plurality of terminal apparatuses further contains a timer unit (24, 13, 14, 15) for detecting that a time elapsed from a time at which an incoming call is detected in the incoming call detecting unit (28, 17), reaches a preset time. The above responding unit (23, 12, 18) in each terminal apparatus starts an operation of responding to the incoming call when the timer unit detects that the above elapsed time reaches the preset time; and an order of priority to respond to an incoming call is predetermined over the plurality of terminal apparatuses, and lengths of the preset times in the plurality of terminal apparatuses are preset in the order of the predetermined priority.</p> |
