Introduction
Welcome to the world of data communications. You have acquired one of the finest intelligent data and
fax modems available today from one of Americas oldest and most respected modem manufacturers:
Multi-Tech Systems, Inc. This users guide will help you install, configure, test and use your modem.
Product Description
The MT5634MU modem incorporates V.90 technology, which enables Internet connections at data
rates up to 56 Kbps* over standard telephone lines. V.90 technology is able to send data downstream
from the Internet to your computer at these speeds because data on the telephone network typically 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 33.6 Kbps, as are downstream
transmissions that are converted more than once on the telephone network.
The MT5634MU is Plug-and-Play in Windows 2000, Windows ME, Windows 98, and Windows 95
operating systems with interactive automatic dialing and command mode configuration. In standard
mode, you can store up to two command lines or telephone numbers of up to 40 characters each in
the modems nonvolatile memory. The modem pulse- or tone-dials, and recognizes dial tones and busy
signals for reliable call-progress detection. The modem can detect AT&T calling card tones. It also has
Caller ID, remote configuration and incorporates self-resetting lightning protection. The MT5634MU is
FCC-registered for connection without notification to the telephone company.
The MT5634MU is a full-duplex intelligent modem with V.42 error correction, V.42bis data
compression, and V.17 (14,400 bps), Class 1 and 2, Group 3 fax capabilities.
The MT5634MU operates with Multi-Techs Global Wizard program. Telephone company technical
requirements differ from country to country. In the Global Wizard program, you simply specify the
country in which you will operate, selecting from a pull-down menu. Global Wizard does the rest,
automatically setting up the correct operating parameters for your modem to operate in your country.
Multi-Techs Flash Wizard utility allows MT5634MU firmware to be updated by the user.
Universal Serial Bus (USB)
Universal Serial Bus (USB), defined by a consortium of industry leaders, permits connection of multiple
low-speed and medium speed computer peripheral devices such as telephones, modems, printers,
keyboards, mice, and scanners; all from a single personal computer port. The specification, based on
an open architecture is quickly becoming a standard feature in new desktop and notebook computers.
Figure 1-1: MT5634MU
* Although K56flex technology is capable of downloads of up to 56 Kbps, FCC regulations currently
restrict ISP modems to downloads of 53 Kbps.

What Can You Do with Your Modem?
Your Multi-Tech MultiMobile MT5634MU is the gateway to the exciting world of telecommunications.
You can use it to access commercial on-line information services such as America Online, Genie, and
Prodigy. These services provide access to databases, encyclopedias, stock reports, news, weather,
and shopping. They provide electronic mail (e-mail) links to subscribers of the same and other
services. Public message areas called forums allow subscribers to trade information and opinions on a
vast array of topics from A to Z, while vendor forums provide hardware and software support from MultiTech and other manufacturers. Online services also allow you to upload and download computer
programs, data files, and updated software such as video and printer drivers.
Your modem can also connect you to the Internet, an international computer network of universities,
libraries, businesses, and government agencies. 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 with modems, to banks, and to service bureaus. You can
also telecommute with your fax modemwork at home while communicating with the office by modem
or fax.
And of course, 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.

Required Equipment
In addition to the contents of your modem package, you need the following equipment.
Computer: Your modem can only be connected to a computer with a USB port.
Telephone Line: You must have a telephone line with 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.
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 data communications
and fax communications software (included with the modem). Data communications 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. Data communications software must be set up, or configured, before you can use it.

Removing Your Old Modem from Windows
When your new modem replaces another modem, the old modem installation remains in Windows even
after you install the new modem. The old modem will still be 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 modem by removing the old modem
from Windows.
From Windows 2000
1. Click Start | Settings | Control Panel.
2. Double-click the Phone and Modems icon and click on the Modems tab.
3. In the list box, select the old modem.
4. Click Remove, 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.
27
Page 28

From Windows ME
1. Go to Start | Settings | Control Panel
2. Double-click the Modems icon to open the Modems Properties screen.
3. In the General tab a list of modems appears. In this list, highlight 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.
From Windows 98/95
1. Click Start | Settings | Control Panel.
2. Double-click the Modems icon to open the Modems Properties sheet.
3. In the list box, select the old modem.
4. Click Remove, 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 3: Configuring the Modem
for Your Country
Different countries have different requirements for how modems must function. Therefore, before you
use the modem, you must configure it to match the defaults of the country in which you are using it.
You can configure the MT5634MU either manually using AT commands or with the Global Wizard. Both
methods are described below.
Using the Global Wizard Utility
The Global Wizard configuration utility is recommended for computers running Windows 95/98/ME/
2000. The Global Wizard can configure your modem for a specific country with just a few mouse
clicks.
1. Insert the MT5634MU Installation CD into the CD-ROM drive. The Autorun dialog box appears.
2. Click Initial Setup and Country Selection. The Global Wizard dialog box appears. Click Next.
3. View the Global Wizard as it searches for your modem and identifies it. Click Next.
4. Select the country in which the modem will be used, and then click Next.
5. Review your choice of country. If it is correct, click Next to configure the modem.
6. When Global Wizard announces that the parameters have been set, click Finish to exit.
Using AT Commands
If you are comfortable using AT commands, you can configure your modem using AT commands. You
must enter these commands in your communication programs terminal window.
To configure the modem for a specific country, execute the following AT commands:
1. Type AT%T19,0,nn (where nn represents the country code). Press Enter.
2. The modem will respond OK.
3. Type AT&F&W (this saves changes). Press Enter.
28
Page 29
Chapter 2 - Installation
4. The modem will respond OK.
5. Type ATI9 (this verifies that country code has been chosen). Press Enter.
6. The modem will display the country code in decimal format followed by an OK.
7. Check to be sure the code for your country is displayed.
If not, repeat procedure to correct.
Here are two examples of country, command, and result codes.
Country AT Command ATI9 Result Code
(Hexidecimal) (Decimal)
Euro/NAM* AT%T19,0,34 (default) 52
Japan AT%T19,0,10 16
Because the list of country codes is continually being updated, we present the complete list on our
Web site: http://www.multitech.com/GlobalModem/config
Step 4: Installing Data Communications Software
Data communications software is designed to send and receive messages about the operation of your
modem. Multi-Tech includes PhoneTools communications software with your modem. However, the
modem will work with most data communications software packages. To install PhoneTools, insert the
Installation CD into the CD-ROM drive; click on the PhoneTools icon. You will be asked to choose
your language. The software will be loaded automatically onto your PC.

and Result Codes

MultiMobileUSB User Guide
AT Commands
AT commands are used to control the operation of your modem. They are so called because each
command must be preceded by the characters AT to get the ATtention of the modem.
AT commands can be issued only when the modem is in command mode or online command mode.
The modem is in command mode whenever it is not connected to another modem. The modem is in
data mode whenever it is connected to another modem and ready to exchange data. Online command
mode is a temporary state in which you can issue commands to the modem while connected to
another modem. To put the modem into online command mode from data mode, you must issue an
escape sequence (+++) followed immediately by the AT characters and the command, e.g., +++ATH
to hang up the modem. To return to data mode from online command mode, you must issue the
command ATO.
To send AT commands to the modem you must use a communications program, such as the
HyperTerminal applet in Windows 95 and NT 4.0, or the 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.
The format for entering an AT command is ATXn, where X is the command and n is the specific value
for the command, sometimes called the command parameter. The value is always a number. If the
value is zero, you can omit it from the command; thus, AT&W is equivalent to AT&W0. Most
commands have a default value, which is the value that is set at the factory. The default values are
shown in the AT Command Summary, which begins on the next page.
You must press ENTER to send the command to the modem. Any time the modem receives a
command, it sends a response known as a result code. The most common result codes are OK,
ERROR, and the CONNECT messages that the modem sends to the computer when it is connecting
to another modem. For a table of valid result codes, see Result Codes at the end of this chapter.
You can issue several commands in one line, in what is called a command string. The command string
begins with AT and ends when you press ENTER. Spaces to separate the commands are optional;
they are ignored by the command interpreter. The most familiar command string is the initialization
string, which is used to configure the modem when it is turned on or reset, or when your
communications software calls another modem.

Chapter 4 - Remote Configuration
Page 48
MultiMobileUSB User Guide
Introduction
Remote configuration is a network management tool that allows you to configure modems anywhere in
your network from one location. With password-protected remote configuration, you can issue AT
commands to a remote MT5634MU modem for maintenance or troubleshooting as if you were on-site.
Basic Procedure
The following steps are valid regardless of whether the connection is established by the local or the
remote Multi-Tech modem.
1. Establish a data connection with a remote MT5634MU modem.
2. Send three remote configuration escape characters followed by AT and the setup password, and
press ENTER. Example: %%%ATMTSMODEM<CR>. You have four tries to enter the correct
password before being disconnected. If the password is correct, the remote modem responds with
OK
3. You can now send AT commands to configure the remote modem.
4. When you have finished configuring the remote modem, save the new configuration by typing
AT&W0<CR>, then type ATO<CR> to exit remote configuration. You can then break the
connection in the normal way.
Setup
CAUTION: If you hang up while you are in remote configuration mode, it may lock up the remote
modem.
Multi-Tech modems are shipped with a default setup password (MTSMODEM). Because anyone who
has an owners manual knows the default setup password, for security you should change the
password and possibly also the remote configuration escape character.
Changing the Setup Password
1. Open a data communications program such as HyperTerminal.
2. In the terminal window, type AT#SMTSMODEM (or AT#Syyyyyy if you have replaced the
MTSMODEM password with yyyyyy) and press ENTER. The modem responds with OK if the
setup password is correct, and ERROR if it is wrong.
3. To change the password, type AT#S=yyyyyy, where yyyyyy stands for the password, and press
ENTER. The password can include any keyboard character, and must be one to eight characters
long. The modem responds with OK.
4. The new password is saved automatically. You can now either enter more AT commands or exit
the data communications program. The next time you remotely configure the modem you must
use the new setup password.
Note: You can only change the setup password locally; you cannot do it remotely. Also, passwords
are case sensitive. The next time you enter the password, it must be in the same case as you set
it up.

Chapter 4 - Remote Configuration
Changing the Remote Escape Character
To increase security, you can change a remote modems remote configuration escape character. The
remote configuration escape character is stored in register S9. The factory default is 37, which is the
ASCII code for the percent character (%). Setting S9 to 0 (zero) disables remote configuration
entirelybut if you do this remotely, you wont be able to change it back remotely!
1. Establish a remote configuration link with the remote modem as described in Basic Procedure.
2. Type ATS9=n, where n is the ASCII code for the new remote configuration escape character, then
press ENTER.
3. Save the new value by typing AT&W and pressing ENTER.
4. Type ATO<CR> to exit remote configuration.

Introduction
Your modem was thoroughly tested at the factory before it was shipped. If you are unable to make a
successful connection, or if you experience data loss or garbled characters during your connection, it
is possible that the modem is defective. However, it is more likely that the source of your problem lies
elsewhere. The following symptoms are typical of problems you might encounter:
None of the LEDs light when the modem is on.
The modem does not respond to commands.
The modem dials but is unable to make a connection.
The modem disconnects while online.
The modem cannot connect when answering.
The modem doesnt work with Caller ID.
Fax and data software cant run at the same time.
If you experience problems, please check the following possibilities before calling Technical Support
(see Appendix D).
None of the Indicators Light
When you plug in the modem, the operating system detects and configures the modem, and the TR
LED should come on.
If the TR LED does not come on, check to see that the software from the MT5634MU Installation CD
has been installed (see Chapter 2, Step 2: Installing the Modem).
The Modem Does Not Respond to Commands
Make sure you are issuing the modem commands from the data communications software,
either manually in terminal mode or automatically by configuring the software. (You cannot
send commands to the modem from the DOS prompt.)
Make sure you are in terminal mode in your data communications program, then type AT and
press ENTER. If you get an OK response, your connections are good and the problem likely is
in the connection setup in your communications software.
Try resetting your modem by unplugging the USB cable from the modem, and then plugging it
back in.
Try rebooting the computer.
The modem might be defective. If you have another Multi-Tech modem, try swapping modems.
If the problem goes away, the first modem is possibly defective. Call Tech Support for
assistance (see Appendix D).

Chapter 5 - Troubleshooting
The Modem Dials But Cannot Connect
There can be several reasons the ZBA fails to make a connection. Possibilities include
lack of a physical connection to the telephone line.
incompatibility between modems.
a busy signal.
a wrong number.
no modem at the other end.
a faulty modem, computer, or software at the other end.
You can narrow the list of possibilities by using extended result codes. Extended result codes are
enabled by default. If they have been disabled, enter ATV1X4 and press ENTER while in terminal
mode, or include V1X4 in the modems initialization string. When you dial again, the modem will report
the calls progress.
If the modem reports NO DIALTONE, check that the modems telephone line cable is
connected to both the modems LINE jack (not the PHONE jack) and the telephone wall jack.
If the cable looks secure, try replacing it. If that doesnt work, the problem might be in your
buildings telephone installation. To test the building installation, plug a telephone into your
modems telephone wall jack and listen for a dial tone. If you hear a dial tone, your modem
might be installed behind a company phone system (PBX) with an internal dial tone that
sounds different from the normal dial tone. In that case, the modem might not recognize the
dial tone and might treat it as an error. Check your PBX manual to see if you can change the
internal dial tone; if you cant, change your modems initialization string to replace X4 with X3,
which will cause the modem to ignore dial tones (note, however, that X3 is not allowed in some
countries, such as France and Spain).
If the modem reports BUSY, the other number might be busy, in which case you should try
again later, or it might indicate that you have failed to add a 9, prefix to the phone number if
you must dial 9 for an outside line.
If you must dial 9 to get an outside line, the easiest way to dial it automatically is to include it
in the modems dial prefix, e.g., ATDT9,. Note the comma, which inserts a pause before the
number is dialed. By inserting 9, into the dial prefix, you do not have to include it in each
directory entry.
To change the dial prefix in Windows 98 HyperTerminal, select Call from the Call menu, click
Dialing Properties, and type 9 in the local and long distance boxes in How I dial from this
location.
If the modem reports NO ANSWER, the other system has failed to go off-hook, or you might
have dialed a wrong number. Check the number.
If the modem reports NO CARRIER, the phone was answered at the other end, but no
connection was made. You might have dialed a wrong number, and a person answered instead
of a computer, or you might have dialed the correct number but the other computer or software
was turned off or faulty. Check the number and try again, or try calling another system to make
sure your modem is working. Also, try calling the number on your telephone. If you hear harsh
sounds, then another modem is answering the call, and the modems might be having
problems negotiating because of modem incompatibilities or line noise. Try connecting at a
lower speed.

The Modem Disconnects While Online
If you have Call Waiting on the same phone line as your modem, it can interrupt your
connection when someone tries to call you. If you have Call Waiting, disable it before each
call. In most telephone areas in North America, you can disable Call Waiting by preceding the
telephone number with *70 (check with your local telephone company).
You can automatically disable Call Waiting by including the disabling code in the modems dial
prefix (e.g., ATDT*70,note the comma, which inserts a pause before the number is dialed).
To change the dial prefix in Windows 98 HyperTerminal, select Call from the Call menu, click
Dialing Properties, check This location has Call Waiting, and select the correct code for
your phone service.
If you have extension phones on the same line as your modem, you or someone else can
interrupt the connection by picking up another phone. If this is a frequent problem, disconnect
the extension phones before using the modem, or install another phone line especially for the
modem.
Check for loose connections between the modem and the computer and the telephone jack.
You might have had a poor connection because of line conditions or the problem might have
originated on the other end of the line. Try again.
If you were online with an online service, it might have hung up on you because of lack of
activity on your part or because you exceeded your time limit for the day. Try again.
The Modem Cannot Connect When Answering
Autoanswer might be disabled. Turn on autoanswer in your data communications program or
send the command ATS0=1 (ATS0=2 if you have Caller ID service) to make sure your modem
in terminal mode.
The Modem Doesnt Work with Caller ID
Caller ID information is transmitted between the first and second rings, so if autoanswer is
turned off (S0=0) or if the modem is set to answer after only one ring (S0=1), the modem will
not receive Caller ID information. Check your initialization string, and if necessary change it to
set the modem to answer after the second ring (S0=2).
Make sure that you have Caller ID service from your telephone company.
Fax and Data Software Cant Run at the Same Time
Communications devices can be accessed by only one application at a time. In Windows 98, you can
have data and fax communication applications open at the same time, but they cannot use the same
modem at the same time.Chapter 6 - Warranty, Service and Tech Support

New Zealand Telecom Warning Notice
The grant of a Telepermit for any item of terminal equipment indicates only that Telecom has accepted
that the item complies with minimum conditions for connection to its network. It indicates no
endorsement of the product by Telecom, nor does it provide any sort of warranty. Above all, it provides
no assurance that any item will work correctly in all respects with another item of Telepermitted
equipment of a different make or model, nor does it imply that any product is compatible with all of
Telecoms network services.
This device is equipped with pulse dialing, while the Telecom standard is DTMF tone dialing.
There is no guarantee that Telecom lines will always continue to support pulse dialing.
Use of pulse dialing, when this equipment is connected to the same line as other equipment, may give
rise to bell tinkle or noise and may also cause a false answer condition. Should such problems occur,
the user should NOT contact the Telecom Faults Service.
The preferred method of dialing is to use DTMF tones, as this is faster than pulse (decadic) dialing
and is readily available on almost all New Zealand telephone exchanges.
Warning Notice: No 111 or other calls can be made from this device during a mains power failure.
This equipment may not provide for the effective hand-over of a call to another device connected to
the same line.
Some parameters required for compliance with Telecoms Telepermit requirements are dependent on
the equipment (PC) associated with this device. In order to operate within the limits for compliance
with Telecoms Specifications, the associated equipment shall be set to ensure that calls are answered
between 3 and 30 seconds of receipt of ringing.
International Modem Restrictions
Some dialing and answering defaults and restrictions may vary for international modems. Changing
settings may cause a modem to become non-compliant with national telecom requirements in specific
countries. Also note that some software packages may have features or lack restrictions that may
cause the modem to become non-compliant.

Appendix B - V.90 Support
Introduction
V.90 is the ITU designation for what had formerly been called V.pcm. The ITU recommendation V.90
was determined at a meeting in Geneva ending February 6, 1998.
V.90 will replace K56flex and other proprietary solutions for PCM connections. Dual-mode client
modem code will be important until all central-site digital modems are upgraded to V.90 and all
interoperability problems have been resolved. Until that time, the Dual-mode client code will provide
reliable connections in K56flex mode to the central-site modems currently deployed.
Your V.90 dual-mode (V.90/K56flex) modem now includes:
· New AT commands,
· New Result Codes in V.90 mode, and
· A-law/m-law selection and various changes to the AT command documentation.
These new functions are explained in documents that are readily-available on the Multi-Tech web site
in Portable Document Format (PDF) files at
manuals.idc . You can download the Acrobat Reader to view PDF files (you may want to bookmark
http://www.adobe.com/prodindex/acrobat/readstep.html before following the download link).
For files with a .ZIP extension, you can download PKUNZIP.EXE to extract the zipped files from the
Multi-Tech FTP site at: ftp://ftp.multitech.com/Utiltities/PKUNZIP.EXE. Using your favorite Web
browser, go to http://www.multitech.com/support/V.90upgrades.htm for additional information on
ITU V.90 support and other Multi-Tech products.
http://www.multitech.com/support/manuals/IDCfiles/
V.90 Troubleshooting
1. Check if the modem firmware is the latest. If not, download the latest from www.multitech.com.
2. Try adding one or more comma (,) characters to the dialed number in the dialing string.
3. Try limiting the speed with the S37 (sets the maximum upstream speed) and S38 (sets the
maximum downstream speed) commands.
4. Perform basic modem/line troubleshooting (check the phone line for noise, try a different line, try
another device on the same line, etc.

Appendix C: Loopback Tests
Introduction
Each time you turn on your modem, it performs an automatic self-test to ensure proper operation. Your
modem also has three diagnostic tests: local analog loopback, remote digital loopback, and local
digital loopback. These ITU-T V.54 loopback tests isolate telephone circuit and transmission problems.
In a loopback test, data from your computer loops through the circuits of your modem and/or a remote
modem before it appears on your monitor. When the loop has been completed, the data on your PCs
monitor should match the original data.
The local analog loopback test allows you to verify that the modems transmitter and receiver circuits
are functioning properly.
The local digital loopback allows you to verify that the local computer or terminal, the two modems,
and the transmission line between them are functioning properly.
The remote digital loopback test allows you to verify that the remote computer or terminal, the remote
modem, the serial ports, the telephone line, and the local modem are functioning properly.
Note: All loopback tests operate at all speeds except 300 bps.
Appendices
Local Analog Loopback Test (V.54 Loop 3)
In this test, data from your computer or terminal is sent to your modems transmitter, converted into
analog form, looped back to the modems receiver, converted into digital form, and then sent to your
monitor for verification. No connection to the phone line is required.

Figure C-1. Local analog loopback test.
Test Procedure
1. Connect the modem to your computer. Using your communication program, set the desired
baud rate and go into terminal mode.
2. Type AT&T1 and press ENTER. This places your modem in analog loopback mode in the
originate mode. A CONNECT message should appear on your display. The modem is now out
of command mode and in a pseudo-online mode.
3. Note that the CD LED is on. If you are set for 14,400 bps or higher, a speed LED should be on.
If the CD LED is not on, there is a defect in your modem.
4. Enter characters from your keyboard. For this test, typing multiple uppercase U characters is
a good way to send an alternating test pattern of binary ones and zeros. The characters
entered should be displayed on your monitor. The TD and RD LEDs should flash when a
character is entered.
61
Page 62
MultiMobileUSB User Guide
5. To exit the test, type the escape sequence +++AT and press ENTER. This puts the modem in
online command mode. Then type either AT&T or ATH to return to command mode.
6. Your modem passes this test if the data received on your monitor are the same as the data
entered from your keyboard. If different data appear on your monitor, your modem is probably
causing the problem, though it could also be your computer. If your modem passes this test,
but you are receiving errors while on line, the remote modem or the phone line could be at
fault.
Remote Digital Loopback Test (V.54 Loop 2)
The remote digital loopback test tests the phone lines and the circuits of both your modem and a
remote modem. In this test, your modem must be on line with another modem that is set up to
respond to a request for remote digital loopback. (Note that some modems might not support remote
digital loopback or might have it disabled.) Data from your computer or terminal is transmitted through
your modem and over the phone line to the remote modem, where it is then looped back to your
modem.

3. Dial the remote modem and establish your online connection.
4. Type the escape sequence +++AT and press ENTER to bring your modem into online

5. Type AT&T6 and press ENTER. The local modem responds to this command by transmitting
an unscrambled marking signal, which causes the remote modem to place itself in digital
loopback mode. Then the local modem exits online command mode and enters data mode.
6. Enter data from your keyboard. For this test, typing multiple uppercase U characters is a good
way to send an alternating test pattern of binary ones and zeroes. Data received by the remote
modem enters its analog receiver, is converted to digital data, is reconverted into analog, and
then is transmitted back to your modem. Your modem passes this test if the data received on
your monitor is the same as the data entered from your keyboard.
7. To exit the test, type the escape sequence +++AT and press ENTER. This puts the modem in
online command mode. The modem should respond with an OK message. If you wish to stay
on line with the remote modem for normal data transmission, type AT&T and press ENTER to
exit the test, then type ATO and press ENTER to return on line. If you wish to terminate the
call, type ATH and press ENTER to hang up.

Appendices
Local Digital Loopback Test (V.54 Loop 2)
The local digital loopback test is identical to the remote digital loopback test with one exception.
Instead of using your modem to signal a remote modem to place itself in digital loopback mode, your
modem is placed in digital loopback mode while the remote modem is not. Data is entered and
transmitted from the remote modem, sent across the phone line to your modem, and looped back to
the remote modem.

Appendix E: Dial-Up Networking
Microsofts Dial-Up Networking (DUN) is a system component of Windows 95, 98, and 2000 that
enables you to connect your computer to a variety of computer systems and networks, including the
Internet.
Dial-Up Networking has been integrated into Windows 2000. If you are using Windows 95, 98, you may
need to install the Dial-Up Networking code from the full-release Windows CD, a companion CD from
your Original Equipment Manufacturer (OEM), or from a complete set of installation (*.CAB) files on
your hard drive. If you are connecting to the Internet, the TCP/IP protocol suite must also be installed
on your computer.
If you are making a Dial-Up connection to the Internet, youll need to set up an account with an
Internet Service Provider (ISP). Your ISP should give you the following information:
· Your access account userid and password
· The access phone number(s) for dialing into your Internet Service Provider
· The protocol used to connect to your ISP (PPP or SLIP)
· Your ISP may or may not provide a static IP address for your computer. If your ISP provides
an IP address for your computer or for their Domain Name Server (DNS), youll need to enter
these addresses when you configure the Dial-Up connection. Many ISPs use dynamic IP
addresses which means they issue your computer a new IP address each time you log into
their system. If your ISP uses dynamic IP addresses, you do not need to configure an IP
address when you create your Dial-Up Connection.
The following instructions will guide you through setting up a basic Dial-Up Networking connection to
the Internet. Many features and settings beyond those shown here are available for use when creating
a Dial-Up connection.

Appendix F: Upgrading the Modem
Introduction
Your modem is controlled by semi-permanent software, called firmware, which is stored in flash
memory. Firmware is nonvolatile; that is, it remains stored in memory when the modem is turned off.
However, it can be changed by either the manufacturer or the user as bugs are fixed or new features
are added.
Since the firmware in your modem is stored in flash memory, you can upgrade it yourself in a few
minutes by using the following procedures and Multi-Techs Flash Wizard program.
Upgrade Overview
The upgrade procedure consists of the following steps, which are described in greater detail in the
following sections.
1. Identify the model number and firmware version of your modem.
2. Identify the current version of the firmware at the Multi-Tech Web site. If your modem
already has the current firmware, there is no need to update it.
3. Download the upgrade file for your modem.
4. Extract the firmware .HEX file and the appropriate flash upgrade program from the file you
downloaded.
5. Document and clear your stored parameters.
6. Upgrade the modems firmware using the .HEX file and the flash upgrade program.
7. Restore your parameters.
Step 1: Identify the Modem Firmware
You must know the model number and firmware version of your Multi-Tech modem to know whether or
not you should update it.
1. Run your favorite terminal program. You can use HyperTerminal for Windows 95, 98, ME,
2000 or Windows NT.
2. In the programs terminal window, type AT&F. Even if you cannot see the AT&F command
on your screen, be sure to type it completely, and then press ENTER. If the modem does
not respond with OK, repeat the AT&F command.
3. Now type ATI3 and record your results. The firmware version should appear first in the
response, which should look similar to the following:
V2.300G-V90_2M_DLS
Step 2: Identify the Current Firmware Version
Identify the current version of the firmware at the Multi-Tech Web site. If your modem already has the
current firmware, there is no need to update it.
1. Using your favorite Web browser, go to http://www.multitech.com/support/MultiMobileUSB/
firmware.asp.
2. Scroll down the table to your modem model number.
3. Look at the firmware version number for your modem.
4. If the firmware version number matches the number found in Step 1: Identify the Modem
Firmware, your modem has the current firmware version, and does not need to be
updated.

Page 75
5. If the firmware version number is greater than the firmware version number found in Step 1:
Identify the Modem Firmware, your modem has an older firmware version. Continue with
Step 3: Download the Upgrade File.
Warning: The first digit of the new firmware must match the first digit of the old firmware,
or the modem may not work properly; e.g., if your current firmware version is 4.16, replace
it only with 4.xx firmware, not 6.xx firmware.
Step 3: Download the Upgrade File
1. If you are not already at the MultiMobileUSB firmware page of the Multi-Tech Web site,
follow the procedure in Step 2: Identify the Current Firmware.
2. Download the upgrade file for your modem by clicking its name, and save the file in a
temporary folder on your hard disk.
3. In the same section of the Web page, download the Flash Wizard utility for your operating
system by clicking it, and save it in the same folder.
Step 4: Extract the Upgrade Files
1. Install the Flash Wizard utility by double-clicking the file name in Windows Explorer.
2. Extract the upgrade files by double-clicking the file name. The extracted files include a
.HEX file, which contains the upgrade data, and a Readme file.
3. Copy the upgrade .HEX file into the Flash Wizard folder, which, in a default installation, is
at C:\Program Files\MultiTech Systems\Flash Wizard\.
Appendices
Step 5: Clear Your Stored Parameters
Before you flash your modem, you should record the parameters that are currently stored in it, so you
can reprogram it after flashing. After you have recorded them, send the AT&F command to the the
modem to clear the stored parameters.
1. Run your favorite terminal program. If you are using Windows 95, 98, 2000, or Windows
NT, you can use HyperTerminal.
2. In the programs terminal window, type AT&V and press ENTER to list your modems
current parameters.
3. Record your parameters by saving the screens and sending them to your printer.
4. Type AT&F and press ENTER to clear your stored parameters and reset your modem to
factory default.
5. Close the terminal program.

Step 6: Upgrade the Modems Firmware
Before you begin the following procedure, read the README.TXT file extracted from the upgrade archive
file. Note the file name for the new firmware (e.g., BkQg300G.hex).
Warning: Never install an older version of firmware over a newer version. Doing so will destroy the
Flash PROM! If the Flash PROM is destroyed, the modem must be sent in for repair.
1. Run Flash Wizard by double-clicking its icon or file name, or by selecting it from the
Start menu. The Identifying Devices dialog box is displayed as Flash Wizard locates and
identifies the devices connected to your system.
Note: If the message ERROR: No valid devices detected is displayed, verify that the
device is powered on and that all cables are correctly and securely attached.
2. Click the modem to be upgraded, and then click Next to proceed.
3. Select the port to be upgraded from the Port list, select the appropriate .HEX file from the
Hex File list, and then click Next to continue.
Note: Do not use FLASHLDR.HEX. This file is used internally by Flash Wizard.
4. The Progress dialog box appears, showing a status bar that indicates the progress of the
upgrade.
Caution: Any disruption of the program during this stage of the upgrade can cause your
modem to become inoperable. Wait for the Next button to become active before
proceeding.
8. When the flash upgrade is complete, the message Programming Complete appears. Click
Next to continue.
9. The Results dialog box appears next. Click Finish to exit Flash Wizard.
Step 7: Restore Your Parameters
Your modem has been updated. You can now open your terminal program to reprogram your modem
parameters or to confirm the update by typing ATI3 in the terminal window and pressing ENTER.
