Abstract
A digital radio link suitable for transmitting digital voice or data signals includes an input circuit (110) for ATM or equivalent cells, a processing circuit to encapsulate the input cells received by the input circuit with at least error check bits (112) so that detected error can identify a specific cell or group of cells, a digital transmission circuit (fig. 12) for transmitting the encapsulated cells via a wireless link, a reception circuit (fig. 12) for receiving encapsulated cells from an opposite side of the digital radio link, a cell decapsulation and error detection circuit (116) connected to the reception circuit and a cell output circuit (110) for connecting the decapsulation circuit to a digital access circuit (AU).
