Explanation: Frame Relay Access Device or Frame Delay Assembler/Dissembler (FRAD) is a device that converts data packets into frames that can be sent over Frame Relay network. It also converts frames from Frame Relay into data packets. Whereas FRWAN stands for Frame relay WAN, VoFR stands for Voice over Frame Relay and FRS stands for Frame Relay Switch. Each of these entities carries out tasks that are different from FRAD.
