virtual channel connection (VCC)

Virtual ChannelConnection (VCC) refers to the virtual channels in two or more sequential circuits that can be combined to form an end-to-end connection. A VCC is a special instance of a Switched Virtual Circuit ( SVC) or a Permanent Virtual Circuit ( PVC). Switching from this ATM connection occurs in the VPI/ VCI, Virtual Path Identifier/VirtualChannel Identifier, fields of each ATM cell.
