Frame relay to provide a telecommunication service for cost-efficient data transmission for intermittent traffic between local area networks (lans) and betwe. Frame relay, an overview frame relay is a synchronous hdlc protocol based network data is sent in hdlc packets, referred to as frames the diagram below of an hdlc frame may be familiar, since without adding specific definitions of how the address, control and crc is used, the diagram is applicable to ibm's sdlc, to x25, to hdlc, to frame relay, as well as other protocols. Benfits of frame relay • frame relay saves money on customer premises equipment (cpe), local access, and interexchange network it also reduces administrative and operations costs.
Frame relay has its technical base in the older x25 packet-switching technology, designed for transmitting data on analog voice lines unlike x25, whose designers expected analog signals with a relatively high chance of transmission errors, frame relay is a fast packet switching technology.
