ABSTRACT:
A method for updating a system program in a switching equipment. Many known, program-controlled switching equipment have a system program deposited in read-only memories. For modifying the system program, a replacement of the read-only memories is necessary, as known. The method updates the system program without having to undertake interventions in the existing switching equipment. Proceeding from a data processing device, administration and maintenance orders are communicated to the administration and maintenance interface of the existing switching equipment, these administration and maintenance orders being misused for the purpose of transmitting an updated system program stored in the data processing device into the switching equipment and in order to reroute the program processing of the system processor located in the switching equipment onto the newly written system program.
