Configuring X.25-to-X.25 PVCs
A SmartSwitch 1800 PVC is a "permanent" connection betwee n two physical 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. X.25 PVC
support includes X.25-to-X.25, and async-to-X.25 (described in Chapter 12). To
display a list of current PVCs (of a ll types), press [A] at the P VC C onfigur ation Menu
(or [A], [D], [E], [A ] from the Main Menu).
To ad d or c hange an P V C , press [B] at the P VC Config urati on Menu. W hen prompt ed,
enter a 1–4- digit Connection ID, which is simpl y a number unique t o this connection,
that identifies the PVC.
