User-Network Interface
The User-Network Interface (UNI) port defines a unidirectional protocol that allows your FRAD to request information about all available PVCs on your service provider's Frame Relay equipment. Your FRAD can then use this information to ensure its proper configuration for the transmission or acceptance of any DLCI defined on your service provider's equipment.
Due to the nature of the UNI, it is the signaling protocol used between the DTE and the DCE. It does not allow the full configuration, administration, and control between two peer DTE devices.
