Data packets are transmitted over a communications link in an interleaved manner. The link comprises a series of time-division multiplexed (TDM) frames, each frame comprising a plurality of time slots, a time slot being shorter than a data packet. Data packets are transmitted over a series of the TDM frames, one time slot in each of the series of frames being used to transmit a portion of that data packet. Different ones of the data packets begin in different TDM frames. Received data packets are allocated a modified header for use over the communications link. The modified header has a shorter address than the address in the received packet header and the modified header can be split into a plurality of parts which are distributed across the length of the transmitted packet. Error protection for the modified header can also be distributed across the length of the transmitted packet and is preferably spaced, within the transmitted packet, from the other parts of the modified header by payload parts of the packet.
