  + 5.1.2 + Frame Relay terminology 
+ + + + + + +
+ + The connection through the Frame Relay + network between two DTEs is called a virtual circuit (VC). Virtual + circuits may be established dynamically by sending signaling messages + to the network. In this case they are called switched virtual circuits + (SVCs). However, SVCs are not very common. Generally permanent virtual + circuits (PVCs) that have been preconfigured by the carrier are used. The + switching information for a VC is stored in the memory of the switch. +

+ + Because it was designed to operate on + high-quality digital lines, Frame Relay provides no error recovery + mechanism. If there is an error in a + frame it is discarded without notification.

+

+ + The FRAD or router connected to the Frame + Relay network may have multiple virtual circuits connecting it to + various end points. This makes it a very cost-effective replacement + for a mesh of access lines. With this configuration, each end point + needs only a single access line and interface. More savings + arise as the capacity of the access line is based on the average + bandwidth requirement of the virtual circuits, rather than on the + maximum bandwidth requirement.

+

+ + The various virtual circuits on a single + access line can be distinguished because each VC has its own Data Link + Channel Identifier (DLCI). + The DLCI + is stored in the address field of every frame transmitted. The DLCI + usually has only local significance and may be different at each end + of a VC.
