- 24 - DATA BASE CREATION IN STORED PROGRAM CONTROLLED SWITCHING SYSTEMS Abstract A time division switching system for providing telecommunications connections as defined by information stored in a plurality of control memories is disclosed. The switching system includes arrangements for transferring a new control program from a central control to a time-slot interchange unit controller associated with a time-slot interchange unit and connected line and trunk units. To generate a data base representing complete calls through the line and trunk units and the time-slot interchange unit, the time-slot interchange unit controller reads the information stored in the control memories, identifies complete telecommunications connections, and stores information defining such complete connections in a data base in a format usable by the new control program.
