| 摘要 |
A data transmission system is described between a central location, connected to a data cell transmission network, for example, an ATM (Asynchronous Transfer Mode) network and a peripheral user-network termination unit, connected to the central location by means of a plurality of digital transmission lines. A lower data transmission rate may be transmitted over each of the digital transmission lines than the data transmission rate of the transmission network, whereby an inverse multiplexing device is provided in each of the central location and in the peripheral user-network termination unit. The inverse multiplexing device in the peripheral user-network termination unit may be assembled from a first and, optionally, one or several further multiplexing modules, whereby each multiplexing module is connected to one of the digital transmission lines. At least one unit is provided for the control and synchronization of partial data cell streams.
