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.

Page 8 of 86 Introduction
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.

Operation procedures and tests Page 11 of 86
Meridian data features Operations and tests
3Verify through the following steps that the ADM and ASIM are properly
configured for connection to the equipment:
— Compare transmission control settings on S2, S3, and S4 of the
ADM to the parameters of the connected data equipment.
— Compare transmission control settings of the ASIM to the
parameters of the connected data equipment.
Note: Do not attempt to change the baud rate while a call is connected.
The connection may lock up.
4Verify through the following steps that the ADM, AIM, ASIM, and
MCDS are not installed out of range from the DTE or the PE:
— Check cable distance between ADM, AIM, ASIM, and MCDS-AC
and DTE.
— Compare wire-gauge selection jumper settings of ADM and
MCDS-AC to the gauge of wire connecting ADM and MCDS-AC
to PE.
— Check cable-distance between ADM, AIM, ASIM, and MCDS-AC
and PE.
Note: In mixed wire-gauge installations, the jumpers should be set to
match the longest wire gauge.
5Verify through the following steps the integrity of the terminal
equipment connected to the ADM, AIM, and MCDS-AC:
— Disconnect ADM from SL-1 terminal and check SL-1 terminal
function.
— Check DTE.
— Check DCE.
6Verify through the following steps that the DLC is properly configured:
— Check option-switch settings for Terminal Number (TN) in
question.
— Check jumper pin positions.
— Check shelf installation (maximum of four DLCs or AILCs per
shelf).

553-2731-300 Standard 4.00 April 2000
Operating procedures
Procedures 1 through 11 provide detailed action-and-response sequences for
various types of calls from the ADM.
Procedure 12 provides detailed action-and-response sequences for various
types of actions from the AIM.
Procedures 13 and 14 provide detailed action-and-response sequences for
various types of actions from the ASIM.
However, the procedures are examples and only recommended, not required.
In many of the procedures, especially those involving simultaneousvoice and
data calls, you are not restricted to following the sequences exactly.

13 Press DATA SHIFT
key. DATA SHIFT lamp on. Data station shifts to data mode.
14 Press RLS key. DDN, DATA SHIFT,
CONNECT, and MODEM
CTRL lamps off.
Call disconnected.
Station idle.
Note:
A data user may use either prefix or default dialing to access and connect the modem automatically.
Prefix dialing allows the data user to choose the modem pool used to select the modem. The user dials a 1
to 4-digit Modem Selection Prefix, a TAC, and the remote computer port DN. If all resources are available, a
data path is established between the data user and the host, and the connect lamp is lit. If either the modem
pool or the trunk route is busy, Ring Again is applied. If the data call is incomplete because the remote port
is unavailable or the call is misdialed, no call progress tones are received to indicate the problem source.
Default dialing assumes that some data users normally wish to connect to the same modem pool for each
call. In this case a default trunk route associated with a Modem Selection Prefix is stored against the user’s
TN. The user only needs to dial the TAC and the remote computer DN. The Meridian 1 system does the rest
and treats the call as if the user had dialed the Modem Selection Prefix. The stored default Modem
Selection Prefix can always be overridden by dialing another Modem Selection Prefix.
When a completely digital path is available from the data station to the remote computer port, an all Digital
Connection Prefix can be designated if the Digital Trunk Interface (DTI) package is equipped. If the DTI
prefix is used, a modem is not connected when the outgoing route is digital. Overflow tone is returned if the
user attempts to use a voice frequency trunk to set up the call.
