PURPOSE:To enable the operation of maximum ability even at an abnormal traffic and to economize the system, by changing the period of execution of an execution program automatically, based on the measuring value of usage rate of a controller, in a stored program control type electronic exchanger. CONSTITUTION:The rate of usage of a controller 22 being a factor of the decision of the processing capability of an exchanger is stored in a memory 23, and when the controller is subject to a load or more, since the fetch of production of calls for exchange can not be made over the processing capability, the period of execution of period program detecting the generation of calls is made slow mainly, allowing not to exceed the processing capability apparently. |
