Method for a centrally controlled telecommunications system, in particular a telephone PABX system, with external input/output devices

摘要

The invention relates to a centrally controlled telecommunications system in which the current data of a program and permanent data memory assigned to the central controller are stored in parallel in an external memory. The data stored in these two memories are compared and, if they do not correspond, the non-corresponding data are shown on a VDU along with their address allocation.
