ABSTRACT:
In a telephone switching system, a method of performing a multiple release jump to a target program release for controlling the system. The system uses duplicate processors and disk file controllers. A new disk file is initialized with new program text and a target release version of office dependent data. This target release version is derived by upgrading the office dependent data one release at a time until office dependent data for the target release is derived. The new program text and target release version of office dependent data is inserted into one member of a duplicate disk file controller system which may either be a new disk file controller or one of the two disk file controllers currently in use in the system. One of a duplicate set of processors, either one of the presently utilized processors, or a new processor being introduced along with the new release is then connected to the peripheral system and the disk file controller for accessing the new program text and target release version of office dependent data. Control is then turned over to that processor. Following successful operation during a soak interval the other member of the duplicate processors is connected to the disk file controller, if disk file controllers have been changed, and the other disk file is updated with the new program text and office dependent data. Advantageously, this arrangement allows a multiple release jump to be made without requiring special software for the particular jump, or without requiring that the multiple release jump be performed one step at a time.
