Configuring and Managing Host-Based X.25 Links - Edition 6 (36939-90057)

11
Preface
This manual describes the configuration, operation, and management of X.25 network
connections for users of HP 3000 Series 900 systems with host-based network
management. Host-based X.25 connections are available on systems running MP EXL
release 3.1 or later MPE/iX release.
You should use this manual only if the connections you are configuring are host-based
X.25 connections. To configure X.25 connections for PC-based systems, refer to
Configuring Systems for Terminals, Printers, and Other Serial Devices, Using the
OpenView DTC Manager, and the HP 3000/iX Network Planning and Configuration
Guide instead of this manual.
You should be familiar with X.25 concepts and know which X.25 facilities are included in
your network subscription. You should also be familiar with NMMGR, the tool used to
configure network connections. If not, refer to Using the Node Management Services
(NMS) Utilities manual for information.
This manual includes step-by-step instructions to assist you in configuring all aspects of
host-based X.25 connections for a system. It includes a description of DTCCNTRL, the
command used to start, stop, dynamically reconfigure, and obtain status about
host-based X.25 system-to-system and PAD connections. It also includes an explanation
of and instructions for using the X.25 log formatting tool, EVLOG.
NOTE MPE/iX, Multiprogramming Executive with Integrated POSIX, is the latest in a series of
forward-compatible operating systems for the H P3000 line of computers.
MPE/iX is a superset of MPE XL. All programs written for MPE XL will run without
change under MPE/iX. You can continue to use MPE XL system documentation,
although it may not refer to features added to the operating system to support POSIX
(for example, hierarchical directories).
MPE V is the old operating system for HP 3000s, not based on the PA-RISC architecture.
MPE V software can be run on the PA-RISC (Series 900) HP 3000s in what is known as
compatibility mode.
The chapters in this manual are organized as follows:
• Chapter 1, “Introduction,” presents an overview of the host-based X.25 capabilities
that are provided as part of the Fundamental Operating System (FOS). It describes
network options, concepts, and diagnostic services for use with host-based X.25 links.
• Chapter 2, “Preparing to Configure DTCs,” details the information you will need
before you can begin to configure DTS for systems with host-based X.25 connections.
It also describes worksheets you can use to plan and record your DTS configuration.
• Chapter 3, “Configuring DTCs Step-by-Step,” provides step-by-step instructions for
configuring DTCs for systems with host-based X.25 connections.
• Chapter 4, “Terminal and Printer Profiles,” describes what are terminal and printer
profiles and how to create and modify your own profiles.
• Chapter 5, “Preparing to Configure X.25 iX System Access,” details the information
you will need before you can begin to configure X.25 iX System Access for systems
with host-based X.25 connections. It also describes worksheets you can use to plan
and record your NS configuration.
