Abstract (en)

[origin: DE19751560A1] The arrangement is connected on one side with a switching component (X15) over a high-frequency data bus (DB), and on the other side with at least one subscriber connection arrangement over respectively at least one subscriber data bus (TB). The multiplexer unit (MUX) contains a reception module (R) for transmission of data from a subscriber connection arrangement to the switching component, and transmitting module (T) for transmission of data from the switching component to a subscriber connection unit. The reception module and the transmitting module comprise individual memories (FIFO0,..., FIFO3) for each subscriber data bus (TB0,..., TB3). Data in the reception module are written with an individual connection arrangement through the respective subscriber, with a pre-settable clock rate (TBCLOCK), into an individual memory. The data are read with a clock rate (DBCLOCK), pre-settable through the switching component. Data in the transmitting module are written into an individual memory, with the clock rate determined by the switching component, and are read with the clock rate determined by the respective subscriber connection arrangement.
