Described is a method, wherein consecutive data slots (1, .. N), which are located between a beginning and an end of a frame (1, .. 4) included in a group of successive frames (1, .. 4), are assigned to intra frame group defined data slot connections for establishing an upstream data transfer from one or more secondary stations (3-1, .. 3-n) through a transmission channel (CH) to a primary station (2). The system may be a hybrid fiber coax data communication system. Several of such data slot connections between one or more secondary stations and the primary station are thus defined. Those data slots (1, .. N) that are assigned to said data slot connections are concentrated, either at the beginning or at the end of the group of successive frames (1, .. 4) by reallocating at least one data slot connection. The method makes an effective and well balanced use of the transmission channel by carrying out a reallocation of at least one data slot connection. The reallocation involves the termination of an existing data slot connection to be reallocated, and the rescheduling thereof in a next group of frames.
