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 transmis-
sions 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 con-
nection 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.

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
MT5600DSDV only
Figure 2-3. Modem connections.
RS232 Connection
Plug one end of the serial cable into the RS232 connector on the modem, and the oth-
er 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.

MultiModemDSVD User Guide 2 Installation
15Multi-Tech Systems, Inc.
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 (MT5600DSDV only)
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 mi-
crophone should have a 1/8-inch mini plug.
Speaker Connection (MT5600DSDV only)
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 elec-
trical 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.

If you use Windows 98, Windows Me, Windows NT 4.0, or Windows 2000, you must
install the modem driver, which is installed using the Windows Plug and Play feature.
Follow the four-step procedure below. The modem driver is used by Windows to con-
trol 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. Insert the MultiModemDSVD system CD into your CD-ROM drive, and then
click OK.
3. Windows installs and configures the modem.
4. Click Finish to exit.
For Windows NT, the Install New Modem wizard presents one additional prompt
before Step 2. At this point, 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. Select your modem. Continue with Step 2 above.
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 appli-
cation 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 mo-
dem and ask you to confirm the selection.

Multi-Tech includes PhoneTools communications software with your modem.
However, the modem will work with most data communications software. To install
PhoneTools, insert the MultiModemDSVD system CD into your CD-ROM drive;
click the PhoneTools icon. You will be asked to choose your language. The software
will then automatically load onto your PC.
Communication programs designed for Windows 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. Though each
communication program is different, the following procedure should work with most

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.

Figure 3-1. Front panel
The MultiModemDSVD has ten LED indicators on the front panel that indicate
status, configuration, and activity:
TD
Transmit Data. The TD LED flashes when the modem is transmitting data to
another modem. The state of the LED matches the TD circuit on pin 2 of the
RS-232C/V.24 interface.
RD
Receive Data. The RD LED flashes when the modem is receiving data from
another modem. The state of the LED matches that of the RD circuit on pin 3 of
the RS-232C/V.24 interface.
CD
Carrier Detect. The CD LED lights when the modem detects a valid carrier
signal from another modem. It is on when the modem is communicating with
the other modem and off when the link is broken.
56
56K Mode (56,000–28,000 bps). The 56 LED lights whenever the modem
connects to an ISP server in K56flex or V.90 mode. The actual connection speed
depends on server capabilities and line conditions.
33
V.34 Mode (33,600–16,800 bps). The 33 LED lights whenever the modem
connects in V.34 mode.
14
V.32bis Mode (14,400 bps–). The 14 LED lights whenever the modem connects
in V.32bis mode.
Note: Although the modem can connect at lower than V.32bis speeds, no speed
indicator lights during the connection.

OH
Off-Hook. The OH LED lights when the modem is off-hook, which occurs
when the modem is dialing, online, or answering a call. The LED flashes when
the modem pulse-dials.
TR
Terminal Ready. The TR LED lights when a datacomm program initializes the
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.
EC
Error Correction (V.42). The EC LED lights continuously when the modem is in
V.42 error correction mode, and blinks when compression is activated.
FX
Fax. The FX LED lights when the modem is in fax mode.
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.

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.

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
