The stuffing packet is used in a radio telecommunications system. This includes a transmitter with a packet forming circuit (BU) introducing a synchronisation sequence in the synchronisation field taken from a synchronisation set (S1-S8). A selection circuit (SC) produces this sequence as a training sequence (S1) or a distinct identification sequence (S2) according to whether the packet is respectively a speech packet or a stuffing packet. A receiver calculates the correlation between a sequence received in the synchronisation field and a reference sequence. A control circuit produces the training sequence as a reference and when the correlation is unsatisfactory it produces the identification sequence as the reference. |
