Abstract:
A method for synchronizing transmission of a data stream between a wireline network node and a base transceiver station, the base transceiver station connected with an air interface within a cellular communications system, the method comprising the steps of:a) transmitting from the base transceiver station to the wireline network node uplink synchronization frames containing uplink synchronization data;b) transmitting from the wireline network node to the transceiver station downlink synchronization frames containing downlink synchronization data in response to receipt of the uplink synchronization frames;c) determining from the uplink synchronization data, an unpacking sequence for time slots of the data stream transmitted over independently routable subchannels of a wireline transport network between the wireline network node and the base transceiver station; andd) unpacking the data stream according to the determined unpacking sequence such that the time slots are unpacked in increasing sequence number order.
