Abstract

PURPOSE:To meet the customer need, by providing a control device, which checks and converts I/O information, independently of the central processing unit of the exchange main body and by changing the microprogram in this device. CONSTITUTION:In typewriter controlling device 4 of the electronic exchange which inputs and outputs control information and maintenance information from teletypewriter 6, input information from teletypewriter 6 is stored temporarily in memory 23 of this control device 4 and is converted to an information string adapted to central processing unit 3. Information from central processing unit 3 is stored temporarily in memory 23 and is converted to an information string adapted to the output of teletypewriter 6. Input information from teletypewriter 6 is discriminated by processor 22 in control device 4, and it is decided by the command analyzing program whether the command should be accepted or not; and if it should not be accepted, the message indicating it is displayed on the type writer. Even if key information of commands are changed according to the customer need, changing of the microprogram of control device 4 copes with this changing.
