User-Network Interface

The User-Network Interface (UNI) port defines a unidirectional protocol that allows your FRAD to request information about all available PVCs in 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.

Because of the UNI's nature (it is the signaling protocol used between the DTE and the DCE), it does not allow for full configuration, administration, and control between two peer devices.
