Abstract: In a multiple access communication network a primary station (2) is coupled to a plurality of secondary stations (4.....18). The secondary stations (4.....18) transmit packets to the primary station in timeslots in a frame. These timeslots are chosen according to the DECT standard. The problem is that it is not possible to transmit 53 bytes ATM cells in an efficient way in the standard DECT packets. According to the present invention, the guard space to deal with the differing transmission delays between several secondary stations and the primary station is reduced. To prevent problems due to the above- mentioned delay differences, the secondary stations (4.....18) comprise compensation means for adjusting the transmission instants of the packets they transmit. By reducing the guard space, it becomes possible to transmit two 53 bytes ATM cells in a double DECT slot, enabling an efficient transmission of ATM cells over a DECT like frame.
