A means of providing access to the Frame Relay network over a DSL connection
Frame relay was designed to be used with ISDN networks. That technology have been surpassed by broadband DSL and fiber optic networks which don't use frame relay so it gradually being phased out.

Frame relay and PPP is used with WAN encapsulation. Frame Relay most closely compares to the OSI data link layer (Layer 2). If you remember that the word "frame" describes the data link layer protocol data unit (PDU), it will be easy to remember that Frame Relay relates to OSI Layer 2. Like other data-link protocols, Frame Relay can be used to deliver packets (Layer 3 PDUs) between routers.

Frame Relay is a packet-switching technology. It works by sending information in packets, which are called frames, through a shared frame-relay network.

Advantages of frame relay over x.25?Frame relay operates at a higher speed(1.544 mbps & currently 44.376mbps) By this it can easily be used instead of a mesh of T-1 or T-3 linesFrame relay operates in just the physical and data link layers. By this it is used as a back bone nwtwork to provide services to protoclols that already have a network layer protocol.It allows brusty data. in case of x.25 and t-line there is a fixed data rateFrame relay allows a frame size of 9000 bytes, which can accommodate all LAN framesFrame relay is less expensive than other traditional WAN
