A data transmission module for transmitting data between a radio communication network that transmits data at a specified rate and data processing means includes network interface radio means for interfacing the data processing means with the radio communication network, data adapter means interposed between the network interface radio means and the data processing means through which data flows under the control of a sequencer means, wherein the sequencer means includes means for frequency-locking the sequencer means to the rate of the network. The data transmission process of the module includes the steps of locking the sequencer means to the rate of the network and synchronizing the flow of the data through the adapter means with the network.
