NS X.25 Migration: NS 3000/V to 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.
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
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:
•
•Asynchronous SERIAL Network Link and bisynchronous
•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.
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 Windows Workstation (using the OpenView DTC Manager software). For more information on configuration using your OpenView Windows Workstation, read Using the OpenView DTC Manager.
