Overview
Introduction
Introduction
This document describes the particular ACC implementation of
recommendation X.25 for use through the ZCOM API, identifying which
of t h e optional features described in the ITU-T (formerly CCITT)
standard have been implemented. This manual describes:
• how to install the protocol.
• protocol s pecific configuration details.
• X.25 programming using the ZCOM and ACC X.25 API routines.
• systems m essages logged by the ACC X.25 subsystem.
• unsolicited status messages generated by the ACC X.25 subsystem.
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) Fo r Terminals Operating In The
Pa cket 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 19 88 and 1993, however,
some features may not be implemented (such as on-line facility
registration).
