Configuring X.25-to-X.25 PVCs
A SmartSwitch 1800 PVC is a "permanent" connection between 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 all types), press
[A]
at the PVC Configuration Menu
(or
[A], [D], [E], [A]
from the Main Menu).
To add or change an PVC, press
[B]
at the PVC Configuration Menu. When prompted,
enter a 1–4- digit
Connection ID
, which is simply a number unique to this connection,
that identifies the PVC.
