Application scenarios
Typically, Frame Relay is used for Frame Relay access. Frame Relay access encapsulates upper-layer packets on a user device by using Frame Relay and connects the user device to a Frame Relay network.
With Frame Relay, you can construct a public or private network as shown in Figure 50 and construct direct connections between data devices as shown in Figure 51.
