experienced by a UBR connection, or as to the cell transfer delay
experienced by cells on the connection.
UNI
User-Network Interface. An interface point between ATM end users and
a private ATM switch, or between a private ATM switch and the public
carrier ATM network defined by physical and protocol specifications per
ATM Forum UNI documents. The standard adopted by the ATM Forum
to define connections between users or end stations and a local switch.
V
VBR
Variable Bit Rate. An ATM Forum defined service category which
supports variable bit rate data traffic with average and peak traffic
parameters.
VC
Virtual Channel. A communication channel that provides for the
sequential unidirectional transport of ATM cells.
VCC
Virtual Channel Connection. A concatenation of virtual channel links
that extends between the points where the ATM service users access
the ATM layer. The points at which the ATM cell payload is passed to,
or received from, the users of the ATM layer for processing signify the
endpoints of a VCC. VCCs are unidirectional.
VCI
Virtual Channel Identifier. Part of the identifier of a particular virtual
circuit in the ATM fabric.
VP
Virtual Path. A unidirectional logical association or bundle of VCs.
VP Tunneling
Virtual Path Tunneling. A virtual path which has been extended to
include a signaling channel and an ILMI channel in addition to the call
channels.
VPI
Virtual Path Identifier. Part of the identifier of a particular virtual circuit
in the ATM fabric.
W
WAN
Wide Area Network. Data communications network spanning very large
geographical areas.
