Definitions for "FRAD"
A concentration and network access device, usually a router, which provides protocol conversion into the frame relay format.
A communications device that converts an asynchronous, outgoing data stream into the format required by a frame relay network, and performs the same function in reverse for an incoming data stream. Similar to the packet assembler/disassemblers (PADs) used in a packet-switched networks, FRADs enable asynchronous devices such as PCs to communicate over frame relay networks. See frame relay and PAD.
(n.) Frame relay assembler/disassembler, used to interface a LAN with a frame relay WAN.
