Abstract
In a method of transmitting asynchronous time-division multiplex transmission link control information the control information produced by the control process is transmitted in the form of control cells. At the transmitting end the control cells conform to a format enabling them to be identified as such, the empty cells to be transmitted on the link are identified and any control cell to be transmitted is substituted on the link for an empty cell which is not transmitted. At the receiving end the control cells are detected and extracted to be used in the control process and are replaced as necessary with empty cells.
