Basic Frame Relay Configuration

North American P1705 & P1730 with at least one non-ISDN interface are configured to have frame relay enabled for that interface by default. P1705 & P1730 shipped outside of North America with at least one non-ISDN interface will have frame relay disabled on that interface as a default setting. See the following page for instructions on switching Frame relay from disabled to enabled.

If the P1730 or P1705 is configured as a frame relay router, it will communicate over WAN connections to other Frame Relay units via Frame Relay Permanent Virtual Circuits (PVC). From 1 to 128 PVC’s may be defined to connect to other frame relay units. Before the P1730 or P1705 can establish a PVC connection to another frame relay router, at least one PVC must be defined. The router is pre-configured to query the frame relay service to auto- learn the required parameters; they may also be set manually.

The DLCI (Data Link Connection Identifier) number for the PVC is assigned by the frame relay service provider. The PVC must be defined on at least one physical links on the router. Refer to the following diagram that shows three router units connected together with two PVCs being configured on each unit. The configuration of the PVCs within the frame relay cloud is controlled by the frame relay service provider.
