deﬁnes a point-to-point interaction between DTEs and DCEs. In simpler terms, when it is time to transmit data, a terminal connects to a modem or packet switch, which then connects to packet switching exchanges (PSEs) and other DCEs to transmit the data to its ﬁnal destination at another terminal. The links by which data is transmitted are called virtual circuits. Virtual circuits allow data transfers between two points on the network through any number of nodes in the network.

Frame Relay Frame Relay provides a packet-switched network that transfers data between DTEs, which can be routers, bridges, and host computers, by creating virtual circuits and using DCEs to transfer the data to its destination.

Frame Relay differs from X.25 (which was developed to work over voice-grade telephone lines) because it was designed to make use of today’s higher speed digital lines. Frame Relay has also been designed to work within complex internetworking environments with extensions referred to as the local management interface (LMI).

LMI provides information about all devices that are accessible on the Frame Relay network by listing all data link connection identiﬁers (DLCIs) connecting the local system with the remote ones. The LMI improves reliability between the DTE and DCE through frequent exchange of keepalive packets that contain status information.

IBM Legacy Networks Each serial port can be attached directly with a Flex-WAN cable to IBM legacy equipment like mainframes and automatic teller machines. See Table 4 for supported IBM protocols.
