Switched Virtual Circuits (SVCs)
SVCs use the signalling protocol to dynamically define connections as they are needed and to release them when they are no longer needed.
SVCs use signalling for:
■Connections initiated by the user/application.
■Connections established and dropped dynamically.
■Varied connection time.
■Connections not automatically
Permanent Virtual Circuits (PVCs)
The most basic connection setup requires the definition of each connection via management. These type of connections generally remain established for long periods of time.
PVC attributes include:
■Connections initiated by network management.
■
■Automatically
■Supported by MIB or other management entity.
The ATM Module does not support PVCs.
