A communication system for transmission of data from an ATM network to a mobile radio system having an interface apparatus coupled therebetween which is operative to remove from the header of each ATM cell entering the system from the network VPI and VCI data. A translator, responsive to the VPI and VCI data, appropriately codes data formed of the remainder of each cell from which the VPI and VCI data has been removed so that it will be received by a mobile user having an address as indicated by the VPI and CPI data. A second translator responsive to codes corresponding to user addresses produces corresponding VPI and VCI data. A unit for recombining the VPI and VCI data with data formed of the remainder of the cell from which it was removed is provided to thereby produce whole cells suitable for transmission from the system to a mobile terminal.
