Time to Hold Data While Waiting

is the time the node will queue data while waiting for a backup DLCI to become active. If neither a backup nor the primary has not become active when this timer expires, the data will be discarded.

Configuring Frame Relay PVCs Across the Node

A SmartSwitch 1800 PVC is a "permanent" connection between two physical ports in the node. This allows communication between the attached devices as soon as they are powered up, without the need to first establish a connection.

To display a list of current PVCs, press [A] at the PVC Configuration Menu (or [A], [D], [E], [A] from the Main Menu). The display will list PVCs of all supported types: frame relay, X.25, async, and async-to-X.25.

To add or change a PVC, press [B] digit Connection ID, which is simply the PVC.
