Configuring X.25-to-X.25 PVCs
An FRM 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 and enter a 1–4-
digit
Connection ID
, which is simply a number unique to this connection, that identifies
the PVC.

It does not matter which end of the PVC is configured first.
