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.

553-2731-300 Standard 4.00 April 2000
The ASIM is desktop mounted and is used to originate and to answer data
calls. It supports the following:
• Keyboard and keypad dialing for asynchronous calling
• Keypad dialing only for synchronous calling
• Automatic set relocation
A Multi-Channel Data System (MCDS) accesses a multiple port computer
and takes the place of several ADMs. The 4-port MCDS Asynchronous Card
(MCDS-AC) performs the same functions as four separate ADMs.
The operations of the Meridian data station described in this publication
should be performed after installation to ensure that each ADM is functional
and is properly configured to provide the data service the customer requires.

Prerequisites
Ensure that commercial power is supplied at the appropriate outlets. Be sure
the power modules required for any SL-1 set Add-on Data Module—for
example, the QMT—equipped at Meridian data station are installed
according to instructions.
Designate or install a test station to have access to external data test
equipment before testing the Meridian data station or stand-alone ADM.

553-2731-300 Standard 4.00 April 2000
Testing procedures
The operating procedures specify the manner the Meridian data station and
stand-alone Add-on Data Module (ADM), Asynchronous Interface Module
(AIM), and Asynchronous/Synchronous Interface Module (ASIM) normally
function.
If there are any differences when testing, follow these steps:
1Check the following connections to verify that the data-related
equipment is properly connected.
— ADM, AIM, and ASIM power
— Power Fail Transfer (PFT)
— ADM-to-SL-1 set
— ADM, AIM, and ASIM-to-DTE
— ADM and ASIM-to-Data Communication Equipment (DCE)
— DCE to peripheral equipment (PE)
— Multi-Channel Data System (MCDS) to PE connections to the
connecting block
— Cross-connectionsattheMainDistribution Frame(MDF)forbridge
taps and eliminate
2Verify through the followingsteps that the appropriate assignments have
been made in the database (LD 10 or LD 11) to allow operation:
— Check Data Line Card (DLC) port and Asynchronous Interface Line
Card (AILC) assignments.
— Check ADM, AIM, and ASIM feature assignments.
— Verify SL-1 and ADM, AIM, and ASIM key assignments.
— Check Modem Pool Line Card (MPLC) or 500-set line card
assignments.
