SONET
Synchronous Optical Network — An ANSI-defined
standard for high speed and high quality digital
optical transmission. It has been recognized as the
North American standard for SDH.
SVC
Switched Virtual Circuit — A connection where
control signalling is used to dynamically establish the
connection and remove it when no longer required.
For example, telephone lines, ISDN and X.25.
Telnet
An asynchronous, virtual terminal protocol that allows
for remote access.
UME
User-to-Network Interface Management Entity —
Software at the UNIs for providing the ILMI functions.
UNI
User-to-Network Interface — The interface between
the user and the ATM switch.
UNI 2.0
ATM Forum UNI specification for the physical and
ATM Layers, the ILMI, OAM and PVC support.
UNI 3.0
An upgrade of UNI 2.0. with traffic control for the
Peak Cell Rate parameter and the operation over
current transmission systems as some of the
additional features.
UNI 3.1
A corrected version of UNI 3.0, this specification also
includes Service Specific Connection-Oriented
Protocol (SSCOP) for error detection and correction.
UNI 4.0
This UNI specification refers to signalling issues.
VC
Virtual Channel — Describes unidirectional flow of
ATM cells between connection (switching or
end-user) points that share the common identifier
number (VCI).
Virtual Connection — A connection established
between end-users (source and destination), where
packets are forwarded along the same path and
bandwidth is not permanently allocated until it is
used.
Virtual Circuit — A connection set up across the
network between a source and destination where a
fixed route is chosen for the entire session and
bandwidth is dynamically allocated.
VCC
Virtual Channel Connection — The end-to-end
connection between two ATM end users is known as
the Virtual Channel Connection. Also defined as a
concatenation of virtual channel link. The VCC used is
identified using two labels: the Virtual Path Identifier
and the Virtual Channel Identifier.
