Step 1: Connect the Modem to Your System
Turn off your computer. Placing the modem in a convenient
location, connect it to your computer’s serial port, to the tele-
phone line, to your leased line, to AC power, and, optionally, to
your telephone.

Dialup Connection
Plug one end of the modular phone cable into the modem’s
LINE jack, and the other end into a public switched telephone
network (PSTN) wall jack.
Note: The LINE jack is not interchangeable with the PHONE
jack. Do not plug the phone into the LINE jack or the line cable
into the PHONE jack.
Note: Regulatory agencies may impose certain restrictions on
equipment connected to public telephone systems. For more
information, see Appendix A of the User Guide.
Two-Wire Leased Line Connection
MT5600BA Plug one end of a two-wire phone cable into the
modem’s LINE jack, and connect the other end to a leased line
wall jack or terminals.
MT5600BL Plug one end of a two-wire phone cable into the
modem’s LEASED jack, and connect the other end to a leased
line wall jack or terminals.
Four-Wire Leased Line Connection
On an MT5600BL only, plug one end of a four-wire phone ca-
ble into the modem’s LEASED jack, and connect the other end
to a four-wire leased line wall jack or terminals. For dial back-
up operation, plug one end of the modular phone cable into the
modem’s LINE jack, and the other end into a PSTN wall jack.
Phone Connection
For voice-only calls, plug a telephone into the modem’s
PHONE jack (optional).

Power Connection
Plug the transformer module into an AC power outlet or power
strip. Plug the transformer module’s cable into the POWER
jack on the modem.
Note: Use only the transformer module supplied with the
modem. Use of any other module voids the warranty and can
damage the modem.
Power-On Test
Test the modem by turning it on (a power switch is located on
the front panel). When you apply power, the modem performs
a diagnostic self-test, indicated by the TM indicator lighting
for a few seconds, after which the LCD should light. If this
does not happen, check that the power switch is on, the trans-
former module supply is solidly connected, and the AC outlet
is live. If these measures do not work, see Chapter 8 of the
User Guide, “Solving Problems.”
Step 2: Install the Modem Driver
If you use Windows 95, Windows 98, Windows Me, Windows
NT 4.0, or Windows 2000, you must install the modem driver.
(If you use Windows 3.1 or another operating system, skip this
step and go to Step 3.)
1. Make sure your modem is connected properly, and then
turn on your computer. Windows should detect your new
modem and open the Install New Modem wizard.
Note: If Windows cannot find a modem, your modem may
be turned off, it may be plugged into the wrong connector
on your computer, or the serial cable may be faulty. See
“None of the LEDs Light When the Modem Is Turned On”
and “The Modem Does Not Respond to Commands”in
Chapter 5 of the User Guide, “Solving Problems.”

2. In the Install New Modem wizard, select Don’t detect my
modem; I will select it from a list, and then click Next. A
dialog box with a list of manufacturers and a list of modem
models appears.
3. Insert the installation CD into your CD-ROM drive, and
then click Have Disk.
4. In the Install from Disk dialog box, select the drive the CD
is in, and then click OK.
5. A list of modems appears. Select your modem from the list,
and then click Next.
6. Select the port the modem is connected to, and then click
Next.
7. Windows installs and configures the modem.
8. Click Finish to exit.
Step 3: Install and Configure Your Software
You may use either the communication program included
with your modem or a third-party program. Communication
programs designed for Windows 95/98/Me and Windows
NT/2000 normally do not need to be manually configured,
since they use the Plug and Play configuration of the Win-
dows modem driver. Communication programs designed for
DOS and other operating systems, however, may need to be
manually configured to work with your modem. Though each
communication program is different, the following procedure
should work with most of them.
1. Install and run your communication program.
2. Find the dialog box or menu that lets you select your mo-
dem. (In Windows Terminal select Settings | Modem
Commands; in HyperTerminal select File | Properties |
Phone Number; and in PhoneTools select Configure |
General Configuration |Communication |Change
Modem.

3. Choose your modem from the software’s modem list. If it
isn’t listed, choose a generic modem and modify the set-
tings as necessary.
4. Change the modem initialization string, if necessary. The
factory default configuration works well for most purpos-
es. To load the factory default configuration, use AT&F. To
load a custom configuration that was saved using the &W
command, use ATZ. Note that the Zcommand must be in
a command string by itself. For a Macintosh, the initializa-
tion string should include the &D0 command. If you do not
want the modem to always answer the phone, add S0=0 to
the string. To use Caller ID with the modem, add S0=2 to
the string (Caller ID information is sent between the first
and second rings, so the phone must ring at least twice be-
for the modem picks up the line). Depending on the soft-
ware, you might have to end the string with a carriage
return character (^M).
Note: To change the modem’s default configuration, type
new commands in the communication program’s terminal
window, adding the &W command to store them in the
modem’s nonvolatile memory. For instance, to create a
default configuration for a Macintosh computer that turns
off autoanswer, type AT&F&D0S0=0&W. The new config-
uration loads automatically whenever the modem is turned
on or receives the ATZ command.
5. Select the port the modem is connected to (normally COM1
or COM2).
6. Select your serial port speed. This can be labeled “maximum
speed,”“DTE bps,”or “baud rate.”Ideally, if you use data
compression, you should set your serial port baud rate to
four times the modem’s maximum transmission speed or
faster; however, few files can be compressed enough to
require speeds that high, and not all serial ports can handle
speeds that high.

7. If the software has an autobaud selection, make sure it is
disabled. Autobaud applies only to older modems, and can
cause problems if enabled.
8. If the software allows you to edit the no-connect messages
(NO CARRIER, BUSY, NO ANSWER, NO DIALTONE),
make sure there is no space between DIAL and TONE in
NO DIALTONE.
9. Refer to the software manual or online help for other con-
figuration choices; in most cases you can accept the default
values.
