List of terms

uplink

An uplink is a logical link representing the connectivity from a border node to an upnode. Uplinks are the basis for horizontal links between nodes.

upnode

An upnode is the node that represents a border nodes’s outside neighbor in the common peer group. It must be a neighboring peer of one of the border node’s ancestors.

usage parameter control (UPC)

A traffic management strategy that enforces traffic characteristics at network access points. UPC evaluates a connection’s traffic characteristics based on the traffic descriptor parameters for that connection, and discards or tags non- conforming cells.

user datagram protocol (UDP)

A simple datagram protocol. UDP is layered directly above the Internet protocol (IP). This protocol does not provide for acknowledging packets or error checking. It has a high data rate but is unreliable for accurately delivering packets.

user-to-network interface (UNI)

1The frame relay service is provided through a standard interface between the user device and the network, called the user-to-network interface. For more information, see the document NN10600-900 Nortel Multiservice Switch 7400/15000/20000 Frame Relay Technology Fundamentals.

2An interface between ATM user equipment and ATM network equipment.

UTC

See Coordinated Universal Time (UTC) (page 35).

UTP

Unshielded twisted pair (a type of cable).

UTP

See universal trunk protocol (UTP) (page 138).

V.11

A ITU-T standard that specifies electrical signal levels for data interfaces. V.11 is used by many physical interfaces such as V.36, V.37, RS-449, and X.21. Nortel Multiservice Switch system V.11 FP provides an X.21 physical interface.

V.35

A standard ITU-T DCE-DTE physical interface for data communication.
