Configuring Async PVCs
A SmartSwitch 1800 PV C is a "permanent" connection between two p hysical/logical
ports in a node. This allows communication between the attached devices as soon as
they are powered up, without having to first make a call to establish a connection.
Async PVC support in the SmartSwitch 1800 includes async-to-async and async-to-
X.25.
To displ ay a lis t of curr ent PVCs , press [A ] at the PVC Configuration Menu (or [A],
[D], [E], [A] from the Main Menu). To add or change a PVC, press [B] at the PVC Con-
figu ra ti on M enu and en t er a 1–4 digit C onnection ID, which is simply a number unique
to this connection, that identifies the PVC.
