Abstract
In a telephone exchange system accommodating a large number of communication lines, a line status display system is provided, which permits display of the status of a large number of lines in a limited display space of the terminal for scale reduction, is capable of flexible use with satisfactory operation control property and will not reduce the processing capacity of the exchange equipment. In a telephone exchange system comprising an exchange equipment (1) and a plurality of terminals (2, 2') accommodated therein, the exchange equipment (1) accommodating a plurality of lines, when detecting a line status change, sends out corresponding information to all the terminals (2, 2'), and the terminals check whether the line is a subject of processing, and if so, displays pertinent information in a predetermined display position.
