NS X.25 Migration: NS 3000/V to NS 3000/iX Release 2.0 or Later
Differences Between NS 3000/V and NS 3000/iX
Differences Between NS 3000/V and
NS 3000/iX
Differences Between NS 3000/V and NS 3000/iX The following
paragraphs summarize differences between NS 3000/V and
NS 3000/iX. Make sure that you account for these differences that could
affect your network when migrating to NS 3000/iX. For information on
operating system migration, refer to the MPE/iX Migration series.
Differences in Hardware
Some NS 3000/V hardware components are not part of an NS 3000/iX
network, such as the ATP for terminal connections, and the INP for
network links.
On an NS 3000/iX network, the DTC provides connections for local or
remote terminals and serial printers. The DTC also provides MPE/iX
access to X.25 through a DTC/X.25 Network Access card. The
Datacommunications and Terminal Subsystem (DTS) LANIC on the
MPE/iX host is used for system-to-system X.25 connectivity.
Unsupported Network Connections
Before migrating your network, identify any unsupported network
connections. The network connections that are not supported on
NS 3000/iX networks are as follows:
• Manual-dial modems.
• Asynchronous SERIAL Network Link and bisynchronous link-level
protocol. To ease migration, you can convert Asynchronous SERIAL
network links to the NS 3000/V Point-to-Point links which can be
converted to NS 3000/iX. Point-to-Point links use the LAP-B
protocol.
• Connections to DS/3000 nodes. DS network services are not
supported on NS 3000/iX. If DS/3000 nodes are part of an existing
network, either migrate them to NS 3000/V or maintain NS 3000/V
connections to the DS/3000 nodes.
Differences in Configuration of Terminals and
Printers
On NS 3000/V networks, the SYSDUMP program is used to perform I/O
configuration which includes configuring terminals, printers, and other
I/O devices and drivers. On NS 3000/iX, terminals and serial printers
are configured on the host (using NMMGR) and on the OpenView
