About the X.25 Product

Introduction

Chapter 116

Introduction

The Hewlett-Packard X.25 link for HP 9000 systems provides

networking link hardware and software to allow HP computer systems to

communicate with other HP and non-HP computers over X.25 packet

switching networks.

The X.25 link implements the CCITT X.25 Recommendations and

contains the components necessary to connect an HP 9000 to a public or

private packet switching network conforming to the CCITT X.25

Recommendation (1980, 1984 or 1988), or to another system in a

back-to-back configuration.

The information in this manual applies to HP 9000 Series 700 and 800

systems that use single, dual, or quad-port communications hardware.

Any differences are specifically noted.

NOTE In a diskless cluster, X.25 software is only supported on the server

system. It is not supported on client systems for this type of

environment.

The following diagram illustrates the X.25 link architecture where:

• solid white boxes represent the product’s integral components.

• lightly shaded boxes represent the product’s protocol components.

• heavily shaded boxes represent optional components (external to the

product) that can be added to the product.

Each component depends on the component(s) below it and must be

installed and running in order to support higher-level components.
