MultiModemDSVD User Guide 1 Introduction
Introduction
Congratulations on your purchase of your MultiModemDSVD! You have acquired
not only one of the finest intelligent data, fax, and voice modems available, but a
modem that can transmit voice and data at the same time. This user guide will
help you to install, configure, test, and use your modem.
Product Description
The MultiModemDSVD modem incorporates both the ITU-T V.90 and the K56flex
protocols, both of which enable Internet connections at data rates up to 53K bps*
over standard telephone lines. Using these protocols, Internet service providers
(ISPs) are able to send data downstream to your computer at high speeds because
data on the telephone network normally is converted from digital to analog only once
before it reaches your modem. Upstream transmissions, and transmissions between
client modems, are limited to data rates of 33.6K bps, as are downstream transmissions that are converted more than once on the telephone network.
The MultiModemDSVD offers interactive automatic dialing and command mode
configuration. You can store up to four command line/telephone numbers of up to
40 characters each in the modem’s nonvolatile memory. The modem pulse or tone
dials, and recognizes dial tones and busy signals for reliable call-progress detection.
The modem can also detect AT&T calling card tones. It is FCC-Registered for connection to telephone networks without notification to the telephone company.
Digital simultaneous voice and data (DSVD) operation allows data transfer and
voice conversation to occur simultaneously during a data connection. On a DSVD
call, a headset or microphone and speaker can be used as the voice interface. Both
local and remote modems must have compatible DSVD technology to support the
DSVD function. The MultiModemDSVD is compatible with the industry-standard
ITU-T V.70 DSVD specification.
™

MultiModemDSVD User Guide 2 Installation
Step 1: Mount the Feet
The modem comes with a strip of self-adhesive plastic feet, which you can optionally mount on the bottom of the modem. To install the feet, simply peel them from
their paper strip and press them into the recesses on the bottom of the modem.
Figure 2-1. Mounting the feet.
Step 2: Change the Speaker Jumper
This step is required only if you intend to connect a monophonic speaker to your
modem. (This step is not required for stereo speakers or for the included headset.) If
you do not intend to connect a monophonic speaker to your modem, skip to Step 3.
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 RS232
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
power and line cables.
2. Turn the modem over.
3. On the bottom of the modem are two screws that hold the case together. Remove
both screws and set them aside.
4. Turn the modem over again.
5. Remove the top part of the modem case.
6. To close the modem, reverse steps 1–5.

MultiModemDSVD User Guide 2 Installation
Step 3: Connect the Modem to Your System
Placing the modem in a convenient location, connect it to your computer’s serial
port, to the telephone line, to AC power, and, optionally, to your telephone. For
voice operations, connect it to the supplied headset or, optionally, to a microphone
and a speaker or sound card.
Note: Do not turn on the modem until you have made all the connections.
PWR RS232 PHONE LINE
Figure 2-3. Modem connections.
RS232 Connection
Plug one end of the serial cable into the RS232 connector on the modem, and the other end into a serial port connector on your computer, such as COM1 or COM2.
Line Connection
Plug one end of the phone cable into the modem’s LINE jack, and the other end into
a phone line 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.
9
MultiModemDSVD User Guide 2 Installation
Note: The Federal Communications Commission (FCC), Industry Canada, and other
government agencies may impose certain restrictions on equipment connected to
public telephone systems. For more information, see Appendix A.
Phone Connection
For voice-only calls, you can optionally plug a telephone into the modem’s PHONE
jack.
Microphone Connection
Plug the microphone plug of the supplied headset into the MIC jack on the side of
the modem. Optionally, plug an unamplified microphone into the MIC jack. The microphone should have a 1/8-inch mini plug.
Speaker Connection
Plug the speaker plug of the supplied headset into the SPKR jack on the side of the
modem. Optionally, 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 you do not have a sound card, you can plug an amplified speaker directly into the
SPKR jack.
Power Connection
Plug the power supply module into an AC power outlet or power strip. Plug the
power supply’s cable into the PWR jack on the modem.
Note: Use only the power supply supplied with the modem. Use of any other power
supply will void the warranty and could damage the modem.
Power-On Test
Test the modem by turning it on (a power switch is located on the right side). When
you apply power, the modem performs a diagnostic self-test, indicated by several
indicators flashing for a second or two, 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 6,
“Solving Problems.”
Surge Protectors and Lightning
Because of power surges and other transient voltages on power and telephone lines,
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. Please note, however,
that not even a surge protector can guard against damage from a nearby lightning
strike.

MultiModemDSVD User Guide 2 Installation
Step 4: 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 5.) The modem driver is used by Windows to control the modem.
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 not have power, 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, “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 your modem’s setup disk into your floppy drive, and then click Have
Disk.
4. In the Install from Disk dialog box, select the drive the installation disk 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.
Removing Your Old Modem Driver
When your new modem replaces another modem, the old modem driver remains in
Windows after you install the new modem, and the old modem 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 from Windows.
1. Click the Start button, point to Settings, and then 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.
11
MultiModemDSVD User Guide 2 Installation
Step 5: 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 supplied by the Windows 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. Turn on your computer 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 &W command, use ATZ. Note that the Z command must be in a command string by itself. For a Macintosh, the initialization 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 for a Macintosh computer that turns off autoanswer, type
AT&F&D0S0=0&W. The new configuration 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 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 (NO CARRIER,
BUSY, NO ANSWER, NO DIALTONE), make sure there is no space between
DIAL and TONE in NO DIALTONE.
9. Refer to the program manual or online help for other configuration choices. In
most cases you can accept the default values.

MultiModemDSVD User Guide 3 Operation
Introduction
Like any modem, your MultiModemDSVD operates only under the control of a
communication program, such as the one included with the modem. It also operates
under other general-purpose data communication programs, such as Windows Terminal and HyperTerminal. For information on how to use the modem with the communication program of your choice, please refer to the program’s documentation.
Unlike other modems, with the MultiModemDSVD you can also simultaneously
send voice and data over a single phone line or, using third-party white-board software, work on a document with someone at another location.
Front Panel
Figure 3-1. Front panel
The MultiModemDSVD has ten LED indicators on the front panel that indicate status, configuration, and activity:
Transmit Data. The TD LED flashes when the modem is transmitting data to
TD
another modem. The state of the LED matches the TD circuit on pin 2 of the
RS-232C/V.24 interface.
Receive Data. The RD LED flashes when the modem is receiving data from
RD
another modem. The state of the LED matches that of the RD circuit on pin 3 of
the RS-232C/V.24 interface.
Carrier Detect. The CD LED lights when the modem detects a valid carrier
CD
signal from another modem. It is on when the modem is communicating with
the other modem and off when the link is broken.
56K Mode (56,000–28,000 bps). The 56 LED lights whenever the modem con-
56
nects to an ISP server in K56flex or V.90 mode. The actual connection speed
depends on server capabilities and line conditions.
V.34 Mode (33,600–16,800 bps). The 33 LED lights whenever the modem con-
33
nects in V.34 mode.
V.32bis Mode (14,400 bps–). The 14 LED lights whenever the modem connects
14
in V.32bis mode.
Note: Although the modem can connect at lower than V.32bis speeds, no speed
indicator lights during the connection.

MultiModemDSVD User Guide 3 Operation
Off-Hook. The OH LED lights when the modem is off-hook, which occurs
OH
when the modem is dialing, online, or answering a call. The LED flashes when
the modem pulse-dials.
Terminal Ready. The TR LED lights when a datacomm program initializes the
TR
modem. It means the modem is ready for an outgoing or incoming call. It goes
off when the datacomm program disconnects the COM port. When it goes off, a
connected modem will disconnect. The state of the TR LED matches that of the
DTR circuit on pin 20 of the RS-232C/V.24 interface.
Error Correction (V.42). The EC LED lights continuously when the modem is in
EC
V.42 error correction mode, and blinks when compression is activated.
Fax. The FX LED lights when the modem is in fax mode.
FX
Note: When you turn on the modem, the speed lights flash briefly as the modem
does a self-test, then the LED for the default modem baud rate lights. The default
rate for the modem is 56K bps. After a call, the LEDs for the connection’s baud rate
remain lit until another call is made or the modem is reset. If you connect at a rate
under 14,400 bps, all speed LEDs 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 5: 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.
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
Dial-Up Networking
Whether you use the Internet for e-mail or for browsing the Web, to connect to it
through your modem, you must first set up a remote-node client program. The one
in Windows 95, 98, Me, NT 4.0, and 2000 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.

Voice Operation
Operation in DSVD mode allows data transfer and voice conversation to occur simultaneously during a data connection. On a DSVD call, a headset or microphone
and speaker can be used as the voice interface. Both local and remote modems must
have compatible DSVD technology to support the DSVD function. DSVD can be
used by running a communications application that supports DSVD. Follow the application instructions. DSVD can also be controlled manually issuing AT commands
to the modem as described in the following sections.
To Originate a Voice Call in Speakerphone Mode
1. In the terminal window of your communications application, type AT and press
ENTER. The modem will respond with OK.
2. Type AT&F and press ENTER to reset the modem to its default configuration.
