SNA Node and Link Configuration
Configuring the SNA Node and Link
result in an indefinite period of inactivity; however,
note that it might be desirable to disable the timer for
permanent virtual circuits (PVCs).
Range: 0-32767 (integer)
Default: 0
Virtual Circuit Type
Required. The type of virtual circuit to be used to
connect to the host: permanent virtual circuit (PVC) or
switched virtual circuit (SVC). The X.25 network
subscription information and the host NPSI
configuration should be used to determine the type of
virtual circuits that are available for this connection.
If you specify PVC, you must also specify the PVC
Number field (see below).
If you specify SVC, you must also specify the Remote’s
X.25 Network Address and Call Direction fields
(both fields are described later in this chapter).
Values: PVC and SVC
Host Configuration:
• PVC: The TYPE operand of the X25.LINE macro for
the PVC must be set to PERMANENT; see Table 2-2.
• SVC: The TYPE operand of at least one X25.LINE
macro must be set to SWITCHED; see Table 2-3.
PVC DATA
Information about the permanent virtual circuit (PVC).
PVC Number Conditionally required. The number
identifying the permanent virtual
circuit that will connect the HP 3000
node to the remote system. This is
found in the X.25 network subscription
information, and is equivalent to the
Logical Channel Number (LCN).
This field is required
only if PVC is
entered for the Virtual Circuit Type
field.
Range: 0-4095 (integer)
X.25 System Access Configuration: If
you followed our recommendation and
configured a specific address key for the
SNA/X.25 PVC (in the PVC Number field
