Introduction
MultiModemDSVD User Guide
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 owner’s manual will
help you install, configure, test and use your modem.
Product Description
The MultiModemDSVD modem incorporates both the older K56flex™ protocol and
the newer ITU-T V.90 protocol, both of which enable Internet connections at data
rates up to 53K bps* over standard telephone lines. Using these protocols, Internet
service providers (ISPs) can send data downstream to your modem at 56K speeds;
however, upstream transmissions, and transmissions between client modems, are limited to data rates of 33.6K bps, as are downstream transmissions that are converted
from digital to analog more than once on the telephone network.
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 telephone is 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.
Features
The MultiModemDSVD offers interactive automatic dialing and command mode
configuration. You can store four command line/telephone numbers, of up to 40
characters each, in the modem’s nonvolatile memory. The modem pulse- or tonedials, 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.
General
• Complies with major ITU-T, TIA, and EIA international standards to ensure compatibility with other modems.
• Distinguishes data, fax, or voice calls using DTMF and tone detection with software packages supporting these features.
• Includes Caller ID to identify the caller’s phone number (available on U.S. products).
• Supports serial port speeds to 230.4K bps with compatible serial ports
*Though this modem is capable of 56K bps download performance, line impairments, public
telephone infrastructure, and other external technological factors currently prevent maximum 56K bps connections.

MultiModemDSVD User Guide
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.
Note: The Federal Communications Commission (FCC) and Industry Canada
impose certain restrictions on equipment connected to public telephone systems.
For more information, see Appendix A.
Phone Connection
For DSVD calls, plug a telephone into the modem’s PHONE jack.
Note: The telephone can operate only when the modem is turned on.
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 on/off 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 5, “Solving Problems.”
8
Step 3: Install the Modem Driver
If you use Windows 95, Windows 98, or Windows NT 4.0, you must install the
modem driver. (If you use Windows 3.1 or another operating system, skip this
step and go to Step 4.) The modem driver is a description of the modem, which Windows uses to control the modem.
Installing the Modem in Windows
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 detect your modem, your modem may be unplugged,
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.
2 Quick Start
3. Insert the MT5600DSVD2 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 from Windows
When your new modem replaces another modem, the old driver remains after you
install the new driver, and the old modem remains selected in HyperTerminal and
other Windows applications. Although you can change the application connection
descriptions one at a time, it is easier to force Windows applications to use the new
driver by removing the old one 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.

MultiModemDSVD User Guide
Step 4: Install and Configure Your Software
You must have communication software installed in your computer to use your
Multi-Tech modem. If you wish to use communication software that is already installed, you should reconfigure it for your new modem; otherwise, install the data
and fax communication software provided with the modem.
1. Turn on your computer and run your communication software.
2. Find the dialog box or menu that lets you specify your modem. (In Windows
Terminal select Settings | Modem Commands; in HyperTerminal select File |
Properties | Phone Number; and in Trio select View | Datacomm | Communications | Setup | Modem | Select from List.
3. Choose your modem from the software’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
software’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. Set the serial port baud rate
to 115,200 bps if your computer has a high speed serial port with a 16550AFN
UART or equivalent and Windows 9x or NT 4.0, or set it to 57,600 bps if it has
Windows 3.1x. If you have an older computer with a 14550 UART, set it to
19,200 bps. Older Macintosh computers can use a serial port baud rate of 57,600
bps; newer ones can use a serial port baud rate of 115,200 bps or 230,400 bps.
To see what UART your serial port uses if you have Windows 3.1x, in Program
Manager select File | Run, type MSD, and press ENTER. Select COM Ports to
see the UART type. If you have Windows 95, select Start | Settings | Control
Panel, and double-click on the Modems icon. In the Modems Properties dialog
box, click the Diagnostics tab, click the port the modem is connected to, and
click More Info to see the UART type. Note that both programs will identify a
10
14550 UART as an 8250A UART. If you have an 80386 or later computer, your
UART is most likely a 14550 or 16550AFN.
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 configuration choices; in
most cases you can accept the default values.
Step 5: Call the Multi-Tech BBS
Test the modem’s data functions by calling the Multi-Tech bulletin board system
(BBS) and downloading REGISTER.DOC, if you have Microsoft Word 6.0 or 7.0, or
REGISTER.TXT if you do not.

Voice Operation
Operation in DSVD mode enables data transfer and voice conversation to occur
simultaneously during a data connection. On a DSVD call, an ordinary telephone
connected to the modem is used as the voice interface. Both local and remote modems must have compatible DSVD technology to support the DSVD function.
To use DSVD, you must first establish a V.34/V.42 data connection between compatible DSVD modems. Once the connection is established, all that is needed to initiate
a conversation is for either party to pick up the phone. The caller hears a ring over
the phone, just like an ordinary call. On the other end, the modem makes a ringing
sound through its onboard speaker. If the phone at that end is not picked up, eventually the caller hears a busy signal. When the modem is turned on but not in DSVD
mode, the phone can be used to make ordinary phone calls.
You can control DSVD either by running a communication program that supports
DSVD, such as the program included with the modem, or by manually issuing AT
commands to the modem as described in the following sections.
To Turn On DSVD Mode
1. In the terminal window of your communication application, type AT and press
ENTER. The modem responds OK.
2. Type AT-SMS=1 and press ENTER to turn on DSVD mode, or type AT-SMS=3
and press ENTER to turn on automatic mode select.
To Turn Off DSVD Mode
1. In the terminal window of your communication application, type AT and press
ENTER. The modem responds OK.
2. Type AT-SMS=0 and press ENTER to turn off DSVD mode.
To Originate a DSVD Call
1. In the terminal window of your communication application, type AT and press
ENTER. The modem responds OK.
2. Type AT&F and press ENTER to reset the modem to its default configuration.
This action ensures that the modem is in automatic DSVD mode.
3. To dial, type ATDTnnnnnnn and press ENTER, where nnnnnnn is the phone
number of a remote DSVD modem.
4. When you see a CONNECT response on your terminal, you can pick up the
phone and talk to the remote user while simultaneously sending data to the remote modem.
16
5. To hang up, type +++ATH and press ENTER.
Note: If DSVD is enabled, the modems will not connect if the V.34 connect rate
is below 12000 bps. The voice link is not maintained in data mode, so if +++ is
typed and the user goes back to data mode, a simulated busy is played to both
modems to tell the users to place their handsets on hook. If you get an ERROR
message when dialing or answering a call, check to make sure the lines are not
in the wrong jacks. A DSVD data connection is terminated by dropping DTR (if
enabled by &D2) or by issuing +++ATH.
To Answer a DSVD Call
1. In the terminal window of your communication application, type AT and press
ENTER. The modem responds OK.
2. Type AT&F and press ENTER to reset the modem to its default configuration.
This action ensures that the modem is in automatic DSVD mode.
3. When the modem responds by displaying RING on the screen, type ATA and
press ENTER to answer the call.
4. When you see a CONNECT response on your terminal, you can pick up the
phone and talk to the remote user while simultaneously receiving data from the
remote modem.

What Can You Do with Your Modem?
Your Multi-Tech MultiModemDSVD is the gateway to the exciting world of telecommunications.
You can use it to access commercial online information services such as CompuServe, America Online, Genie, and Prodigy; or the Internet. Like the commercial
online services, the Internet provides e-mail services, public message areas, and access to information and software, much of it easily accessed through the World
Wide Web.
Other uses include direct links to colleagues, to banks, and to service bureaus. You can
also telecommute with your fax modem—work at home while communicating with
the office by modem or fax, for you can use your modem to exchange faxes with any
fax machine in the world, enabling you to communicate quickly with businesses and
organizations that do not have direct modem communications.
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.
Required Equipment
In addition to the contents of your modem package, you need the following equipment.
Computer
Your modem can be connected to any computer with an RS-232/V.24 serial port,
such as most PCs. It can also be connected to the RS-422 serial ports on Apple
Macintosh computers.
To use the modem at its highest speeds, a PC must have either of the following:
• A serial port with a 16550AFN UART
• A Multi-Tech ISI (Intelligent Serial Interface) card, such as the ISI551 (single
port), ISI552 (dual port), or ISI608 (8 ports)
These devices can handle serial port rates up to 115,200 bps, which is sufficient for
all uploads and most 56K downloads. For downloading highly compressible files at
56K speeds, however, your serial port should be capable of speeds to 230,400 bps.
Serial Cable
To connect the modem to your computer, you must provide a shielded serial cable,
obtainable at computer stores and many office supply stores. The cable should have
a male DB-25 connector at the modem end. For PCs, the other end may have a male
DB-25 connector or a female DB-9 connector, depending on your particular computer and whether you are using the COM1 or the COM2 serial port.
20
Most Macintosh computers require a round, 8-pin, mini-DIN connector. The
Macintosh serial cable should be wired for hardware flow control.
Telephone Line
You must have a telephone line with a jack (connector) that accepts the cable that
comes with the modem. If you do not have a telephone jack near your computer,
you should install one before proceeding.
In North America, do-it-yourself telephone extension kits and accessories are available wherever telephones are sold. You may also hire an independent contractor or
your local telephone company to install an extension. If you want a separate line for
your fax modem, you must contact your telephone company.
Communications Software
To operate your modem, you must have a data, fax, and voice communication program, such as the one included with your modem. Communication software simplifies control of the modem by guiding you through the process of selecting your
serial port, your port speed, and other variables, and then storing your settings, including frequently called phone numbers, so they can be recalled with the stroke of
a key or the click of a mouse. Communication software must be set up, or configured, before you can use it.
3 Features
Connections
To use your modem, you must connect it to your computer (“RS232”), to a telephone line (“LINE”), to a telephone (“PHONE”), and to a power source (“PWR”).
PWR RS232 PHONE LINE
Figure 3-1. Power and communications connectors.
Connecting to the Computer (“RS232”)
Using a matching serial cable, connect the RS232 connector on the modem to one of
the serial port connectors on the back of your computer. On a PC, there are usually
two serial ports named “COM1” and “COM2.” COM1 typically uses a DB-9 connector, whereas COM2 may use a DB-25 connector. Most Apple Macintosh computers
use round mini-DIN-8 connectors for the serial ports. Choose the one marked with
the icon of a telephone; the Macintosh gives priority to that port and will not interrupt your communications link. Be sure to tighten the mounting screws on the DB
connectors.
Connecting to the Telephone Line (“LINE”)
Plug one end of the cable provided with the modem into the telephone jack in your
home or office. Plug the other end into the LINE jack on the modem.
