Permanent Virtual Circuit (PVC) A permanent virtual circuit (PVC) is a connection that is permanently established between two or more nodes in frame relay and asynchronous transfer mode (ATM) based networks. It enables the creation of a logical connection on top of a physical connection between nodes that communicate frequently or continuously.
PVC is a very durable and long lasting construction material which can be used in a variety of applications, either rigid or flexible, white or black and a wide range of colours in between. Due to its very nature, PVC is used widely in many industries and provides very many popular and necessary products.
