Telnet, Uni | IBM ATM OC-3c specs

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.

GLOSSARY 5

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.
