Glossary

User Plane Connection

Signaling operates in the control plane (doing control-type functions such as setting up the connection). After signaling is finished, it drops out of the way and the established connection is used to move data. This moving of payload data is done in the user plane. Control and user planes are parts of the conceptual model of ATM.

Variable Bit Rate
