Introduction

This document describes the particular ACC implementation of recommendation X.25 for use through the ZCOM API, identifying which of the optional features described in the ITU-T (formerly CCITT) standard have been implemented. This manual describes:

The X.25 protocol is defined in ITU-T Fascicle VIII.2 - Recommendation X.25 'Interface Between Data Terminal Equipment (DTE) And Data Circuit-Terminating Equipment (DCE) For Terminals Operating In The Packet Mode and Connected to Public Data Networks by Dedicated Circuit'. This was originally issued at Geneva 1976 and subsequently amended at Geneva in 1980, Malaga-Torremolinos in 1984, and Melbourne in 1988.

This implementation supports the 1980 and 1984 specifications. You may use this product on X.25 recommendations 1988 and 1993, however, some features may not be implemented (such as on-line facility registration).
