A PVC is a permanent channel connection between two ATM devices. PVC's allow network transmissions to be started without having to first establish a connection with the end point ATM device. When a PVC is constructed, the end points of the connection will agree upon a path in which data will travel, and therefore agree upon the route that data will travel to reach its destination.
A virtual circuit in an ATM network that is always up when the switch is up. Used for signalling and routing information.
A virtual path through a network characterized by fixed endpoints defined by the network operator at service subscription. A single physical path may support multiple PVCs and SVCs. Compare with Switched Virtual Circuit. Click here to view a diagram
A term found in frame relay and ATM networking in which a virtual connection between two fixed end-points is established through the network. See also switched virtual circuit .
A point-to-point connection between two specific locations on an ATM, Frame Relay, of X.25 network. PVCs are pre-defined by the ATM, Frame Relay, or X.25 network administrator. See also SVC.
A virtual circuit set up by the provider that establishes a dedicated point-to-point connection between two users.
A channel through an ATM network provisioned by a carrier between two end points, used for dedicated long-term information transport between locations.
A virtual circuit (VC) is a logical connection between an X.25 DTE and an X.25 DCE. PVCs are analogous to leased lines because they always connect two X.25 DTEs.
a connection oriented circuit that may be set up by software between any two nodes of a switched network
a virtual circuit that provides a guaranteed connection between two or more points when needed without having to reserve or commit to a specific physical path in advance
A circuit in a shared cloud (i.e. Frame Relay) that imitates a leased line between two points on the cloud.
A term found in frame relay and ATM networkingi n which a virtual connection between two fixed endpoints is established through the network. See also Switched Virtual Circuit.
A point-to-point connection that is established ahead of time. A group of PVCs defined at the time of subscription to a particular service is known as a virtual private network (VPN).
A virtual circuit that is an assigned connection over a packet switched network and is not switchable by the users.
A virtual data connection related to Frame Relay service that is dedicated for a customer's use between two specified locations. Click here for more information about Frame Relay Services. [Back to Glossary Table of Contents
A virtual circuit assigned to a preconfigured static route.
A PVC is what connects the customer's port connections, nodes, locations, and branches to each other. All customer ports can be connected to each other, resembling a mesh, but PVCs usually run between the host and branch locations.
A path through a network from one fixed point to another that appears to be a dedicated circuit; however, the path can be changed and rerouted if necessary....
A virtual circuit that has a logical channel permanently assigned to it at each DTE. A call establishment protocol is not required. Contrast with switched virtual circuit.
A pre-established virtual circuit. See virtual circuit and Frame Relay.
A defined virtual link with fixed end points that are set up by the telecommunications carrier.
