A term used in ATM and Frame Relay networks, UNI is the interface between the ATM end user and a private ATM switch. It also can represent the interface between a private ATM switch and the public carrier ATM network.
An interface point between ATM end-users and a private ATM switch, or between a private ATM switch and the public-carrier ATM network, UNI is defined by physical and protocol specifications from the ATM Forum UNI documents. It is the standard adopted by the ATM Forum to define connections between users or end-stations and a local switch.
User Network Interface. The protocol defines connections between ATM end-stations and the ATM switch including signaling, cell structure, addressing, traffic management, and adaptation layers.
user network interface. The interface between ATM users or end stations and an ATM switch or network. The UNI interface is defined in the ATM Forum UNI documents.
the physical and electrical demarcation point between the user and the public network service provider.
User-to-Network Interface (of a signaling interface)
User to Network Interface. The interface between end user and the network or the switch. Used in ATM and frame relay. Also see NNI.
See User Network Interface.
User Network Interface. In ATM environments, the point at which the user joins to the network.
User-to-Network Interface - The interface between the user and the ATM switch.
User Network Interface - The interface, defined as a set of protocols and traffic characteristics, between the CPE and the ATM network.
user-network interface; a defined interface between the user and the public network
An asynchronous transfer mode (ATM) interface specification, defined by the ATM Forum. See ATM.
user-to-network interface. Used for ATM connection to CPE. See also NNI.
User-Network Interface. ATM Forum standard that defines how private CPE interacts with private ATM switches. A connection that directly links a user's device to an ATM network (usually, through an ATM switch). Also, the physical and electrical demarcation point between the user device and the ATM switch. There are two types of ATM UNI: Private UNI - used to interconnect an ATM end-device with an ATM switch that is not in the public network; for example, a switch that is managed as part of the same corporate network. Public UNI - used to interconnect an ATM end device with an ATM switch that is in the public network.
User network interface. Standards-driven protocol that defines connections between the ATM user (end-station) and the ATM network (switch).
User-Network Interface. ATM Forum specification that defines an interoperability standard for the interface between ATM-based products (a router or an ATM switch) located in a private network and the ATM switches located within the public carrier networks. Also used to describe similar connections in Frame Relay networks. See also NNI, Q.920/Q.921 and SNI (Subscriber Network Interface).
User Network Interface; ATM protocol for the interface between ATM users (end-stations) and an ATM network; see also NNI.
User-to-network interface. Generic term to indicate interfaces to both public or private frame relay or ATM networks.Typically end point devices such as client workstations, client servers, or ATM routers. The current UNI specification describes the signaling protocols that let users set up connections between ATM devices in customer premises equipment or public carrier equipment. The UNI specification includes support for switched virtual circuits.
