Linking Up with Frame Relay

Overview
Frame Relay (FR) is a new wide area link technology. It was the first of
several fast packet technologies to become commercially available. Other
fast packet technologies include Switched Multimegabit Data Service
(SMDS) and asynchronous transfer mode (ATM).

Figure 1. Frame Relay Network
A Frame Relay network is shown in figure 1. Frame Relay networks are
composed of fast switching nodes connected by high-speed digital trunks.
User devices, routers in this case, are connected to the switching nodes
through digital circuits such as T1s. The Frame Relay standards define the
interface between the user device and the Frame Relay network. How data
is routed within the network is determined by the manufacturer of the
