Meridian data features Operations and tests

Introduction
This document describes how to operate the Meridian data station and how to
test its on-line transmission performance.
A colocated data station consists of a QSU-type SL-1 telephone and an
Add-on Data Module (ADM) connected to data terminal equipment.
Note: References in this publication to ADMs imply QMT7, QMT8,
and QMT12 ADMs.
The Meridian colocated data station permits data calling and regular
telephone calling to and from a single SL-1 telephone. The data station also
allows several optional calling features associated with the SL-1 telephone to
be used in conjunction with data calling.
Astand-aloneADM,whenconnectedtoadataterminal(forexample,without
a companion SL-1 terminal), provides services associated with Meridian data
calling that do not require user intervention.
Configuring each stand-alone ADM appropriately is critical to the proper
function of Meridian data stations.
The Asynchronous Interface Module (AIM) provides the interface between
an RS-232-C compatible asynchronous Data Terminal Equipment (DTE)
through its Asynchronous Interface Line Card (AILC).
The AIM may be desktop or wall-mounted and is used to originate and to
answer data calls. It supports keyboard dialing.
The Asynchronous/Synchronous Interface Module (ASIM) provides the
interface between an RS-232-C compatible asynchronous or synchronous
DTE and the Meridian 1 system.
