NS X.25 Migration: NS 3000/V to NS 3000/iX Release 2.0 or Later
Differences in X.25 Support
Facilities
Following are the supported facilities of the DTC/X.25 XL Network
Link.
Security
When configuring a host, you can now set security for each remote
system using the Security field on the X.25 SVC Address Key Paths
screen. System to System Local User Groups (LUGs) are now assigned
on the DTC instead of on the host. The LUG provides security in the
same way a CUG does, but you don’t have to subscribe to a CUG.
