Step 2: Change the Internal Jumpers
This step is required only if:
Ö You intend to use the modem on a leased line.
Ö You intend to add a monophonic external speaker to your modem with the voice option. No
changes are needed for stereo.
This will require you to open the modem and move one or more jumpers on the modem’s printed
circuit board.
Warning: The following procedure must be performed by authorized service personnel.
Caution: The circuit board can be harmed by static electricity. Before you open the case, touch a
grounded object, such as the metal chassis of your computer, to discharge any static electricity in
your body, then touch the metal shell of the modem’s RS-232 connector to ensure that there is no
voltage difference between you and the modem.
Opening the Modem
1. If the modem is connected, turn it off and remove all connecting cables, including the power and
line cables.
2. Turn the modem upside down.
3. On the bottom of the modem are two screws, which hold the case together. Remove both
screws and set them aside.
4. Turn the modem right side up.
5. Remove the top part of the modem case.

Changing the Dial-Up/Leased-Line Jumpers
As shipped from the factory, your modem is configured for normal dial-up operation. That is, the
modem must dial a phone number to connect to another modem. To use the modem on a leased line,
you must change jumper J10 to select leased line operation, and J11 to select whether it will be the
originating or the answering modem. If dial-up operation is selected, J11 has no effect.
See Chapter 3 for additional leased line information.
· The factory default is the answer position. This makes the modem the answering modem on the
leased line.
· To use the modem on a leased line, move the J10 jumper plug from the default dial-up position to
the leased line position.
· To make the modem the originating modem on the leased line, move the J11 jumper plug to the
originate position.
Changing the Voice Jumper
The speaker jumper (J8) is next to the external speaker jack (see Figure 2-2).
· The factory default position of the voice jumper is set for a stereo speaker or sound card. A
jumper plug covers both pins of the J8 jumper.
· To use the modem with a monophonic external speaker, remove the jumper plug from the J8
jumper pins. You can store it by placing it on one jumper pin.

Connect a Microphone and/or Speakers (Optional)
PWR RS232 PHONE LINE
Figure 2-4. MultiModemZBAV connections.
Connect the Microphone
For voice mail or speakerphone applications, plug an unamplified microphone into the MIC jack on
the side of the modem. The microphone should have a stereo 1/8-inch mini plug. Do not use a
monophonic microphone.
Connect the Speakers
For speakerphone or voice mail applications, use a 1/8-inch plug male-to-male stereo patch cord to
connect the SPKR jack on the side of the modem to the LINE IN jack on your sound card. If your
sound card does not have a LINE IN jack, use its MIC jack. The stereo male-to-male patch cord can
be purchased at a local PC retail store.
If you do not have a sound card, you can plug an unamplified speaker directly into the SPKR jack.
Connect the Modem to the AC Power Outlet
The power switch is located on the right side of the modem. Make sure it is set to OFF. Plug the the
universal power supply into the PWR jack on the modem. Then plug one end of the country-specific
power supply cord into the universal power supply and the other end into a power outlet or power
strip.
Note: Use only the power supply supplied with the modem. Use of any other power supply voids the
warranty and can damage the modem.

MultiModemZBA-V-V92 User Guide
2 Installation
Power-On Test
Test the modem by turning it on. When you turn it on, the modem performs a diagnostic self-test,
after which the 56 indicator should light. If this does not happen, check that the power switch is on,
the power supply is solidly connected, and the AC outlet is live. If these measures do not work, see
Chapter 8, “Solving Problems.”
Surge Protectors and Lightning
Your modem has automatic, self-resetting protection to protect it from lightning-induced electrical
spikes on the telephone line. Nonetheless, large power surges and nearby lightning strikes can
damage or destroy your modem. Therefore, we recommend that you plug the modem into a surge
protector rather than directly into a wall outlet, preferably a surge protector that provides protection
against electrical spikes on the telephone line as well as on the power line. Note that not even a
surge protector can guard against damage from a nearby lightning strike. During an electrical storm,
it is safest to unplug your computer equipment from both the power outlet and the telephone line.
Step 4: Install the Modem Driver
If you use Windows 95 or above, you must install the modem driver. The modem driver tells Windows
how to control the modem. In Windows 95 and above, the MTMoh Modem on Hold program is
installed at the same time (see Chapter 7). If you use a Linux operating system, please see Appendix
F. If you use another operating system, please refer to its documentation for modem installation
information.
Installing the Modem Driver
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 8, “Solving Problems.”
2. Insert the system CD into your CD-ROM drive, and then click OK.
3. Windows installs the modem driver.
4. Click Finish to exit.
Removing an Old Modem Driver
When a new modem replaces another modem, the old modem driver remains in Windows, and
the old modem driver is still selected in HyperTerminal and other Windows applications. Though you
can change the application connection descriptions one at a time, it is easier to force Windows
applications to use the new modem by removing the old modem driver from Windows.
1. Click the Start button, point to Settings, and click Control Panel.
2. Double-click the Modems icon to open the Modems Properties dialog box.
3. In the list box, select the old modem.
4. Click Remove, and then click Close.
5. The next time you dial a HyperTerminal connection, it will select your new modem and ask you to
confirm the selection.

Step 5: Configure the Modem for Your Country
Different countries have different requirements for how modems must function. Therefore, before you
use your modem, you must configure it to match the defaults of the country in which you are using it.
You must also do this if you move the modem to another country after it has been configured for the
first country. You can use one of two configuration methods:
1. Use the Global Wizard to Configure Your Modem
2. Use AT Commands to Configure Your Modem
Using the Global Wizard to Configure Your Modem
The Global Wizard configuration utility is recommended for computers running Windows 95 or newer.
1. Insert the MultiModemZBAV-V92 CD into the CD-ROM drive. The Autorun menu should appear.
2. Click Initial Setup and Country Selection.
3. Choose either:
- Run Global Wizard from CD. This will not load the wizard onto your hard drive, or
- Install Global Wizard on the HD. This will install the wizard onto your hard drive for future use.
4. The Global Wizard dialog box appeard. Click Next.
5. The Global Wizard searches for your modem and identifies it. Click Next.
6. Select the country in which the modem will be used. Click Next.
7. Review your choice of country. If it is correct, click Next to configure the modem.
8. When Global Wizard announces that the parameters have been set, click Finish to exit.
Using AT Commands to Configure Your Modem
Non-Windows users can configure the modem using AT commands. You must enter these
commands in your communication program’s terminal window.
1. Run your favorite communication program, and open the program’s terminal window.
2. To configure the modem for a specific country, type AT%T19,0,nn, where nn is the country code
in hexadecimal notation, and then press ENTER. The message OK displays.
3. To verify the change, type ATI9 and press ENTER. The country code displays in decimal format.
Country AT Command (hexadecimal) Result code (decimal)
Euro/NAM AT%T19,0,34 (default) 52
A complete list of country codes can be found on the Multi-Tech Web site at

Step 6: 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 and above normally do not need to be manually
configured, since they obtain configuration information from Windows. 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 modem. (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 program’s modem list. If it isn’t listed, choose a generic modem
and modify the settings as necessary.
4. Change the modem initialization string, if necessary. The factory default configuration works well
for most purposes. To load the factory default configuration, use AT&F. To load a custom
configuration that was saved using the &
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 befor
the modem picks up the line). Depending on the software, 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 that turns off autoanswer, type
AT&FS0=0&W. The new configuration loads automatically whenever the modem is turned on or
receives the ATZ command.
W
command, use ATZ. For a Macintosh, the initialization
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 communication program has an autobaud selection, make sure it is disabled. Autobaud applies
only to older modems, and can cause problems if enabled.
8. If the program allows you to edit the no-connect messages (

connection remains lit until another call is made or the modem is reset. If you connect at a rate under
14,400 bps, all protocol indicators remain off after the connection is broken, even though the modem
is still turned on.

Configuring the Modem
Your modem normally is configured either through Windows or through the communication program
you are using. The default settings work best for most purposes. See “Step 6: Install and Configure
Your Software” in Chapter 2 for help in setting up your communication program.
You can also configure your modem directly by typing AT commands in the terminal window of a
communication program. See Chapter 4 for descriptions of the modem’s AT commands.
PhoneTools Features
Using the PhoneTools communications program included with your modem, you can:
Upload and download data files.
Send faxes at preset times.
Store incoming voice messages and faxes.
Retrieve stored messages, faxes, and telephone numbers (telephone number retrieval requires
Caller ID service from your telephone company).
Print a received fax.
For detailed information about operating your modem under PhoneTools, please refer to the PhoneTools online documentation.

Leased Line Operation
The MultiModemZBA-V-V92 modem can be used on a two-wire leased line.
A leased line is a private, permanent, telephone connection between two points. Unlike normal dialup
connections, a leased line is always active. The modems automatically connect when they are
attached to the line and are turned on. Because a leased line is always active, one of the two
modems on the line must be configured as the originate modem and the other as the answer modem;
however, it does not matter which is which.
In the event of an interruption, leased line modems automatically reconnect when the data line or
power is restored.
Setup
1. Open the modem and change jumper J10 to select leased-line operation, and jumper 11 to select
either originate or answer operation, depending on how you intend to use the modem. See
Chapter 2 for the detailed procedure.
2. Connect a modular telephone cable to the LINE jack. Connect the other end of the cable to a
two-wire leased line jack or terminals supplied by the telephone company.
3. Turn on the modem.
4. This completes the setup for two-wire leased line operation. Upon completion, the modem
attempts to connect to the modem at the other end of the leased line. If the remote modem has
not yet been configured for leased line operation, you may turn off the local modem until the
remote one is ready.

V.92 Operation
Because the V.92 protocol is new and still largely unsupported by central servers, some features are
disabled by default in the initial release of the MT5634ZBA-V-V92 modem. This section describes the
status of the V.92 features in the initial release. Please note that the V.92 special features require
connection to a V.92-capable server.
General. The V.92 protocol is enabled by default. If the MultiModemZBA-V-V92 detects another
V.92 modem during the handshake phase, they will connect in V.92 mode; otherwise, they will
connect in V.90 mode or the highest mutually acceptable mode. The AT command that controls
this is +MS=.
Commands. AT commands specific to the V.92 protocol and the new V.44 compression protocol
begin with the plus character (+). These commands are in this manual. Also, the S109 register
has been modified to support V.92.
PCM Upstream. PCM Upstream is disabled by default. To upload files at speeds above 33.6
kbps, you must enable PCM Upstream using the command +PIG=1. Please note that this requires
connection to a V.92-capable server. Also, please note that since upload speeds are affected by
line conditions, meeting the previous requirements cannot guarantee speeds above 33.6 kbps.
Quick Connect. Quick Connect, which shortens the handshake time with another V.92 modem, is
disabled by default. To enable it, use the command +PQC=0. Quick Connect speeds connect
times by skipping the line test during the handshake and using the configuration from the last data
connection. Quick Connect works best when line conditions are consistent from call to call. If line
conditions are variable, enabling Quick Connect can actually increase the connect time slightly.
Modem on Hold. Modem on Hold enables you to put a V.92-capable server on hold while you
take another call (see Chapter 7). Modem on Hold operation is possible only with the MTMoh
Modem on Hold program included with the MT5634ZBA-V-V92. MTMoh is initially supported only
on Windows 95, 98, and Me. However, Windows NT, 2000, and XP support is expected soon, and
may be available by the time you receive your modem.
Firmware updates for the MT5634ZBA-V-V92 can be downloaded from http://www.multitech.com/
SUPPORT/MultiModemZBA/firmware.asp. Please see the Appendix for update instructions. MTMoh
updates can be downloaded from http://www.multitech.com/SUPPORT/software/.
Connecting to the Internet
Your Multi-Tech modem is your gateway to the Internet and the World Wide Web. To access the
Internet and Web via your modem, you must establish a dial-up account with an Internet service
provider (ISP). To locate an ISP near you, look in a local directory or computer publication. Your ISP
should provide you with the following information:
User name (also called user ID)
Password
Access number (the number you call to connect to the server)
Host name and/or domain name
Domain Name Server (DNS) server address
If, besides the Web, you use the Internet for e-mail and newsgroups, your ISP should also provide
you with the following information:
E-mail or POP mail address
POP server address
Mail or SMTP address
News or NNT server address

MultiModemZBA-V-V92 User Guide
3 Operation
Dial-Up Networking
Before you can connect to the Internet, you must set up a remote-node client program on your
computer. The Windows version is called Dial-Up Networking. Dial-Up Networking establishes your
connection to the ISP’s server, which is the shared computer that manages calls from clients (your
computer) to the Internet. Most, if not all, Windows browsers start Dial-Up Networking automatically
when you open them.
For instructions on how to set up Dial-Up Networking, consult your ISP or your operating system’s
online help or printed documentation. Many ISPs include with their service a program that will install
and configure Dial-Up Networking automatically for you.
Sending a Fax
You can use the PhoneTools program included with your modem to send and receive faxes directly
from your computer. The following procedure uses print capture, which enables you to fax a
document directly from the Windows application in which you created it without opening PhoneTools.
1. Install PhoneTools if it is not already installed.
2. Create a document in a Windows application, such as a word processor, graphic editor, or
spreadsheet. To fax the document, keep the document open and select the Print command from
the File menu.
3. Select CAPTURE FAX +BVRP as the printer driver, and then click OK. The Send Fax wizard
appears.
4. In the Recipient section, type the required information or extract it from the Phone Book by
clicking
5. In the Template section, optionally select a cover page and type a cover message.
6. Select the document to be sent. The default file when sending from within a Windows application
is Capture.dgr.
7. Select the date and time to send the document, if you do not want to send it immediately.
8. Click Finish to start the transmission.

issue the command ATO.
To send AT commands to the modem you must use a communications program, such as
HyperTerminal or the PhoneTools communications program included with your modem. You can
issue commands to the modem either directly, by typing them in the terminal window of the
communications program, or indirectly, by configuring the operating system or communications
program to send the commands automatically. Fortunately, communications programs make daily
operation of modems effortless by hiding the commands from the user. Most users, therefore, need
to use AT commands only when reconfiguring the modem, e.g., to turn autoanswer on or off.
