Introduction

Overview

Congratulations on the addition of an Asynchronous Data Module (ADM) to your

AT&T Integrated Services Digital Network (ISDN) 8500 series display terminal.

Following our tradition of excellent quality and high reliability, the ADM is

designed to provide you with the latest in telecommunications technology.

This manual is intended for use with AT&T’s ISDN 8500 series display terminals

equipped with an asynchronous EIA-232 (Electronic Industries Association) data

interface. Currently, the 8510, 8520, and 8528 terminals are the only members

of the ISDN 8500 series display terminals with this feature. Should AT&T

introduce other 8500 series display terminals with an asynchronous EIA-232

interface in the future, this document will be updated accordingly. The

asynchronous data functionality of the 8500 series display terminals is provided

by an Asynchronous Data Module (ADM). The ADM is a printed circuit board

within the 8500 series display terminal.
