Abstract

PURPOSE:To attain interrupting communication during communication by displaying an interrupting incoming with an interrupting incoming detecting means and switching a line switching circuit, an NCU switching circuit and an incoming displaying signal line switching circuit with a switching means. CONSTITUTION:While a first information processor 5 communicates with a second information processor 12, an NCU 4 sends an incoming displaying signal to an interrupting incoming detecting means 11 when a third information processor 13 send a prescribed interrupting signal through the NCU 4. According to this action, the interrupting incoming detecting means 11 displays the interrupting incoming. When a line switching circuit 8, an NCU switching circuit 10 and an incoming displaying signal switching circuit 21 are switched by a switching means 6, the third information processor 13 is connected to the first information processor 5 and interrupting communication goes to be possible. At such a time, the second information processor 12 is connected through an NCU 2 to a holding circuit 7 and an NCU holding circuit 9 and a holding condition is obtained.
