access rate

The clock speed (port speed) of the connection (local loop) to the Frame Relay cloud. It is the rate at which data travels into or out of the network.

A DLCI is a number that identifies the end point in a Frame Relay network. This number has significance only to the local network. The Frame Relay switch maps the DLCIs between a pair of routers to create a permanent virtual circuit. It is used to identify logical connections.
Local Management Interface (LMI)
A signaling standard between the customer premises equipment (CPE) device and the Frame Relay switch that is responsible for managing the connection and maintaining status between the devices.
