Frame Relay Access Device
     
         (FRAD) Hardware and software that turns
        {packets} from {TCP}, {SNA}, {IPX}, etc into {frames} that can
        be sent over a {Frame Relay} {wide area network}.
     
        FRADs are a hot topic in data comms because companies like
        {Netlink}, {Motorola}, {Stratacom} are making lots of money
        out of them.
