The invention relates to a method for configuring a network termination unit for the packet-by-packet asynchronous transfer mode transmission of data. According to said method data subdivided into cells and assembled into packets are transmitted either at a constant data rate (CBR), for example in the case of voice or video data, or at a non-constant data rate (UBR). The data cells or packets are received and transmitted via the network termination unit, which constitutes an interface between a transmission line and data terminal. The number of data cells contained in each transmitted or received data packet is determined in the network unit ( 10 ) and from this number it is determined whether the ATM connection is carried out at a constant (CBR) or non-constant (UBR) data rate. The data packets of a CBR connection have processing priority over the data packets of a UBR connection. |
