Overview

Frame Relay uses statistical multiplexing technology and can establish multiple virtual circuits over a single physical cable to fully utilize network bandwidth. Frame Relay uses data link connection identifiers (DLCIs) to identify virtual circuits. Frame Relay uses the Local Management Interface (LMI) protocol to maintain the status of each virtual circuit.

The following interfaces support Frame Relay:

• Synchronous serial interfaces, including synchronous serial interfaces derived from other interfaces.

• POS interfaces.

• POS channels.
