Abstract

A digital radio link suitable for transmitting digital voice or data signals includes an input circuit for ATM or equivalent cells, a processing circuit to encapsulate the input cells received by the input circuit with at least error check bits so that detected error can identify a specific cell or group of cells, a digital transmission circuit for transmitting the encapsulated cells via a wireless link, a reception circuit for receiving encapsulated cells from an opposite side of the digital radio link, a cell decapsulation and error detection circuit connected to said reception circuit and a cell output circuit for connecting said decapsulation circuit to a digital access unit. The system includes structure for allocating more than one type of service, such as low delay service for voice transmission and extensive forward error correction service for data transmission.
