Keeping Standards up-to-date

Standards are living documents which reflect progress in science, technology andsystems. To maintain their currency, all Standards are periodically reviewed, andnew editions are published. Between editions, amendments may be issued.Standards may also be withdrawn. It is important that readers assure themselvesthey are using a current Standard, which should include any amendments whichmay have been published since the Standard was purchased.

Detailed information about joint Australian/New Zealand Standards can be found byvisiting the Standards Australia web site at www.standards.com.au or StandardsNew Zealand web site at www.standard.co.nz and looking up the relevant Standardin the on-line catalogue.

Alternatively, both organizations publish an annual printed Catalogue with fulldetails of all current Standards. For more frequent listings or notification ofrevisions, amendments and withdrawals, Standards Australia and StandardsNew Zealand offer a number of update options. For information about theseservices, users should contact their respective national Standards organization.

We also welcome suggestions for improvement in our Standards, and especiallyencourage readers to notify us immediately of any apparent inaccuracies orambiguities. Please address your comments to the Chief Executive of eitherStandards Australia International or Standards New Zealand at the address shownon the back cover.

This Standard was issued in draft form for comment as DR 99242.

PREFACE

This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee

IT/1, Information SystemsInterconnection to supersede AS/NZS 3621:1994. This Standard is

identical with and has been reproduced from ISO/IEC 8208:1995, Information technologyData

communicationsX.25 Packet Layer Protocol for Data Terminal Equipment.

The objective of this Standard is to provide network designers with a specification for the procedures,

formats and facilities at the packet layer for data terminal equipment operating in conformance with

ITU-T Recommendation X.25.

The term informative has been used in this Standard to define the application of the annex to which

it applies. An informative annex is only for information and guidance.

As this Standard is reproduced from an International Standard, the following applies:

(a) Its number does not appear on each page of text and its identity is shown only on the cover andtitle page.

(b) In the source text this International Standard should read this Australian/New Zealand

Standard.

(c) A full point should be substituted for a comma when referring to a decimal marker.

References to International Standards should be replaced by references to equivalent

Australian/New Zealand Standards, as follows:
