PURPOSE:To secure the switching of the subscriber data without discontinuing the call process control but by reading the subscriber data which is not under communication, completing the renewal of all subscriber data through renewal of the subscriber storage region in the memory and then resetting the channel unit. CONSTITUTION:In case the switching is given to the alteration, increment, erasion and others for the subscriber data through the electronic exchange of the storage program system, the subscriber data is memorized previously in subscriber data memory 6. And temporary memory 5 posseses the storage region for the subscriber data read out from memory 6. Here in case the switching is required for the increment/decrement, alteration and others of the subscriber data, the contents of memory 6 is changed into the new subscriber data. And the switching is requested to CPU1 for the subscriber data via channel unit 3. As a result, CPU1 reads out the data of the subscriber not under communication, renews the subscriber storage region in memory 6 and resets circuit 3 after renewal of all subscriber data. In this way, the subscriber data can be switched without discontinuing the call process control. |
