Screen) until you get to the screen you need next.
X.25 Link Data Screen
Once you have specified the PU and LU information, you are ready to
configure the communications link parameters and virtual circuit data
for the X.25 link. You do this on the “SNA Node Configuration: X.25
Link Data” screen. Select this screen by pressing
[f1] (Go To LINKDATA)
on the “SNA Node Configuration: PU Data” screen. (You can go directly
to this screen from any screen by typing @SNANODE.
nodename .X25LINK
in the command window and pressing
[ENTER].)
Before You Use This Screen
The PVC or SVC that SNA/X.25 Link is going to use must have already
been defined in the X.25 System Access configuration and the DTC
Manager configuration or the DTS configuration. So, before you
configure the X.25 link parameters and virtual circuit data on the “SNA
Node Configuration: X.25 Link Data” screen, you must have done the
tasks described below.
For an SNA/X.25 PVC:
• Configured a logical channel identifier (LCI) range in the DTC
Manager configuration or the DTS configuration. The PVC Number
you specify on the “SNA Node Configuration: X.25 Link Data” screen
must be within the LCI range you configured.
• Configured a network interface (NI) for the SNA/X.25 PVC in the
X.25 System Access configuration. The value you specify for NS
Network Interface Name on the “SNA Node Configuration: X.25
Link Data” screen must match the NI name you configured.
• Configured an address key for the SNA/X.25 PVC in the X.25 System
Access network interface configuration, if you want to reserve the
PVC for only SNA/X.25’s use.
For an SNA/X.25 SVC:
• Configured a network interface (NI) for the SNA/X.25 SVC in the
X.25 System Access configuration. The value you specify for NS
Network Interface Name on the “SNA Node Configuration: X.25
Link Data” screen matches the NI name you configured.
• Configured a facility set in the network interface with the same
parameters as the facility set on the host. The HP 3000 facility set
can be configured for the SNA/X.25’s SVC use only, or for use by any
SVC. We recommend that you configure the facility for only
SNA/X.25’s use, because that ensures that SNA/X.25 receives only
incoming calls intended for it.
