The invention describes a system architecture for a digital switching system in which signalling and packet data are exchanged between terminal stations (E) and a superordinate unit (PAD) without collision and without loss of data. In a subordinate unit (LCi), data flowing in the direction of the superordinate unit (PAD) are separated and signalling data are preprocessed. Signalling and packet data flowing in the direction of the terminal station are switched on the same data channel and, with the aid of a monitoring facility, a control signal characterizing the state of the data channel is passed on to the superordinate unit (PAD). The architecture is modular and can thus be adapted variably to different packet data volumes.
