Introduction

Introduction
The HDLC.FRAME Protocol is part of the Advanced Communications Controller (ACC) family of products This manual provides configuration information that is specific to that protocol.
There are differences in the use of the HDLC.FRAME protocol, which depend on the type of physical interface in use. The physical interface types fall into one of two categories. These are “E1/T1” and all other types (for example “RS232” or”X.21”). Throughout this document these categories are referred to as E1/T1 or non-E1/T1.

Product Features

The HDLC.FRAME protocol adds HDLC framing (including the checksum) to outgoing messages and strips the HDLC framing (including the checksum)from incoming messages. The HDLC.FRAME protocol performs frame checksum processing.
The HDLC.FRAME protocol is fully defined in the following ISO standards document:
ISO 3309 HDLC Procedures - Frame Structure Fifth edition 1993-12-15 Reference number ISO/IEC 3309:1993(E)
14 Chapter1
Overview

Supported Devices

Supported Devices
The HDLC.FRAME protocol implementation maybe used to supportany protocol which requires HDLC framing conforming to the above published standard at the physical layer.

Modes of Operation

The HDLC.FRAME implementation supports a single mode of operation:
• Two way continuous communication (normal)

Data Rules

This release of the HDLC.FRAME protocol product is qualifiedfor use at line speeds up to the limit set by the interface card hardware.
