PURPOSE:To carry out the entire initialization control when an initialization request is found by providing an accessible common memory by each terminal control circuit side and a central control circuit side independently. CONSTITUTION:When initialization request signals from terminal control circuits 21-2n are produced, the effect is stored in a common memory 20 by a control signal receiving circuit 12. When a normal control action of a central control circuit 11 is idle, the storage content in the memory 20 is decided. When the initialization request is found, the prescribed initialization processing is carried out. Thus the entire prescribed initialization can be carried out without adversely affecting the normal control action of the circuit 11. Consequently such troubles will not occur that another normal call control section is interrupted or delayed, and a stable call control action can be executed. |
