Chapter 2 – Installation
Location of the Jumpers
Note: J8 is the Jumper for the Modem with Voice Option
Changing the Dial-Up/Leased-Line Jumper
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.
•
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.

Chapter 2 – Installation
Connect the Modem to Your PC
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.
Connect the Modem to the Telephone Line
Plug one end of the modular telephone cable into the modem’s LINE jack and the other end into a standard
phone wall jack.
Important: The LINE jack is not interchangeable with the PHONE jack. Do not plug the telephone into the
LINE jack or the line cable into the PHONE jack.
Note: Regulatory agencies may impose certain restrictions on equipment connected to public telephone
systems. For more information, see Appendix A.
Connect the Two-Wire Leased Line (Leased Line Only)
Plug one end of a two-wire telephone cable into the modem’s LINE jack and the other end to a two-wire
leased line wall jack or terminals.
Note: Before you can use the modem on a leased line, you must first change the internal jumpers. See “Step
2: Change the Internal Jumpers.”
Connect the Modem to a Phone (Optional)
If you want to connect a phone to the same line as the modem, plug it into the modem’s PHONE jack.
Important: The PHONE jack is not interchangeable with the LINE jack. Do not plug the telephone into the
LINE jack or the line cable into the PHONE jack.
Connect a Microphone (Voice Option)
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 Speakers (Voice Option)
For speakerphone or voice mail applications, use a 1/8-inch mini 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.
For the global products, plug 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.
For Non-global products, plug the power supply lead into the PWR jack on the modem. Plug the transformer
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.
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 7, “Troubleshooting.”

Step 4: Configure the Modem for Your
Country or Region – Global Product Only
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/region in which you are using it. You must also do this if you
move the modem to another country/region after it has been configured for the first country/region. 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 isrecommended for computers running Windows 95 or newer.
1. Insert the MultiModem Product CD into the CD-ROM drive. The Autorun menu should appear.
2. Click Initial Setup and Country/Region 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 appeared. Click Next.
5. The Global Wizard searches for your modem and identifies it. Click Next.
6. Select the country/region in which the modem will be used. Click Next.
7. Review your country/region choice. 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 a terminal emulation software.
2. To configure the modem for a specific country/region:
Type AT%T19,0,nn, where nn is the country/region code in hexadecimal notation.
Click ENTER. The message OK displays.
3. To verify that the correct country/region has been configured, type:
ATI9 and click ENTER.
The country/region code displays:
Example:
Country/Region
AT Command (hexadecimal)
Country code (decimal)
Euro/NAM
AT%T19,0,34 (default)
52
A list of country/region codes can be found on the Multi-Tech Web site at:

Chapter 2 – Installation
Step 5: Configure the modem for best
performance
With Micorsoft Operating System, you can configure your modem using HyperTerminal.
Ensure that there are not other applications running that could take control of the com port to which the
modem is connected. Disable fax service and routingt and remote access if running.
To configure your modem, follow these steps:
1. Ensure that the modem serial cable supplied with your modem is connected.
2. In Hyperterminal, select Start I Programs I Accessories I Communications I HyperTerminal.
3. In the Connection Description Name window, enter any name and click OK.
4. In the Connect To dialog, click the down arrow on Connect Using and select Direct to Com Port X when X is
the Com Port connected to your modem. Click OK.
5. In the Com X Properties dialog, select a speed of 115200 in the Bits per second window and leave everything
else at default. Click OK. The TR LED on the modem should light.
6. Now you should be in the HyperTerminal screen. Enter ATE1 and press ENTER. You should get a response of
OK. You are now communicatintg with your modem.
7. To configure your modem, 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. For a Macintosh or a device that does not
provide TR, 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 and +VCID=1 to the
string (Caller ID information is sent between the first and second rings, so the phone must ring at least twice
before 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.
Modem Serial Speed Guidelines
If your modem is being used with a terminal with keyboard, set the serial speed to be four times or more higher than the
speed of your modem. This will maximize throughput if compression is enabled.
If you modem is connected to a server or other device without a keyboard, then the serial speed should match the serial
speed of the server’s port. Consult the AT Command Reference Guide for the specific commands.
With Linux disbributions that have Minicom installed, use this application to configure the modem. For more information,
refer to the software manuals and the software’s online help for other configuration choices and for information on how to
use the modem with other communication programs.

Chapter 3 – Operation
About the Front Panel
The LED indicators on the front panel indicate status, configuration, and activity:
TD – Transmit Data. Flashes when the modem is transmitting data to another modem.
RD – Receive Data. Flashes when the modem is receiving data.
CD – Carrier Detect. 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). Lights whenever the modem is set for or connects using the V.90 or V.92 protocol.
The actual connection speed depends on ISP server capabilities and line conditions.
33 – V.34 Mode (33,600–2,400 bps). Lights whenever the modem connects using the V.34 protocol.
14 – V.32bis Mode (14,400–7,200 bps). Lights when the modem connects using the V.32bis protocol. The modem can
connect at lower than V.32bis speeds, but no speed indicator lights during the connection.
OH – Off-Hook. Lights when the modem is off-hook, which occurs when the modem is dialing, online, or answering a
call. Flashes when the modem pulse-dials.
TR – Terminal Ready. Lights when a communications program is using the modem. It means the modem is ready for an
outgoing or incoming call. It goes off when the communications program disconnects the serial port. When it goes
off, a connected modem will also disconnect.
EC – Error Correction (V.42). Lights continuously when the modem is in V.42 error correction mode, and flashes when
compression is activated.
FX – Fax. Lights when the modem is in fax mode.
Note: When you turn on the modem, the protocol indicators flash briefly as the modem does a self-test, after which the
56 indicator lights. After a call, the indicator for the protocol used in the 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.

PhoneTools Features
With 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 MultiModem ZBA 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 J11 to select either
originate or answer operation, depending upon how you intend to use the modem. Refer to Chapter 2,
Step 1: Change the Internal Jumpers, for the detailed procedure.
2.
3.
Connect a modular telephone cable to the LINE jack. Connect the other end of the cable to a two-wire
lease-line jack or terminals supplied by the telephone company.
Turn on the modem.
V.92 Operation
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. 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 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.

Chapter 5 – Remote Configuration
Chapter 5 – Remote
Configuration
Remote configuration is a network management tool that allows you to configure MT5634ZBA modems remotely from
one location. With password-protected remote configuration, you can issue AT commands to a remote modem for
maintenance or troubleshooting as if you were on site.
Basic Procedure
The following steps can be used when the connection is established by the local or the remote modem.
Note: The remote computer must be running and a communication program must be ready for a data connection, which
will be indicated by a lighted TR indicator on the front of the modem.
1. Establish a data connection with a remote MT5634ZBA modem.
2. Send three remote configuration escape characters followed by AT and the setup password, and press
ENTER. Example: %%%ATMTSMODEM. 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 and
pressing ENTER.
5. Type ATO and press ENTER to exit remote configuration. You can now break the connection in the normal
way.
Setup
Multi-Tech modems are shipped with a default setup password (MTSMODEM). Because anyone who has the User
Guide knows the default setup password, you should change the password and possibly also the remote configuration
escape character. Record your new password and escape character for future reference.
Changing the Setup Password
1.
Open a data communications program such as HyperTerminal or PhoneTools.
2. In the terminal window, type AT#SMTSMODEM (or AT#Sxxxxxxxx if you have replaced the
MTSMODEM password with xxxxxxxx) 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=xxxxxxxx, where xxxxxxxx stands for the password, and then
press ENTER. The password can include any keyboard character, and can be up to eight characters long.
The modem responds with OK.
CAUTION: Passwords are case-sensitive. The next time you enter the password, it must be in the same
case as you set it up.
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 wish to set up the modem, you must use the new password.
Changing the Remote Escape Character
To further improve security, you can change a remote modem’s remote configuration escape character either
locally or remotely. 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
entirely.
CAUTION: If you do this remotely, you won’t 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, and then
press ENTER.
3. Save the new value by typing AT&W and pressing ENTER.
4. Type ATO and press ENTER to exit remote configuration.

Chapter 6 – Callback Security
Chapter 6 – Callback Security
This chapter describes how to use callback security with your modem. Callback security protects your network from
unauthorized access and helps control long-distance costs. When callback security is enabled, all callers are requested
to enter a password. If a valid password is received, the modem hangs up and returns the call by dialing a phone number
that is stored with the password. The person being called back must then enter the password a second time to establish
a connection.
Up to 30 callback passwords and dialing strings can be stored in the modem. Each dialing string can be up to 34 or 35
characters long and can contain commands as well as phone numbers. For mobile callers, the dialing string can be
programmed to allow the caller to bypass the stored callback number by entering a temporary callback number, to enter
an extension at the callback number, or to make a direct connection without callback.
For local security, the passwords and dialing strings that are stored in the modem are protected from tampering by a
setup password, which you should change when you set up the modem. You can further protect the modem against
tampering by disabling its ability to respond to most AT commands. To check for attempted break-ins, you can request
the modem to display the number of failed password attempts.
Your modem was shipped with a default setup password (MTSMODEM). The same password is used for both callback
security and remote configuration (Chapter 5). Because anyone who has access to this guide has access to the default
password, you should change the password during your initial setup.
Changing the Setup Password
1. Open a data communications program such as HyperTerminal or PhoneTools.
2. In the terminal window, type AT#SMTSMODEM (or AT#Sxxxxxxxx if you have replaced the MTSMODEM
password with xxxxxxxx). 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=xxxxxxxx, where xxxxxxxx stands for the new password, and then press
ENTER. The password can include any keyboard character, and can be up 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 HyperTerminal
or the data communications program. The next time you wish to set up the modem, you must use the new
password.
CAUTION: Passwords are case-sensitive. The next time you enter the password, it must be in the same case as
you set it up.
Turning Callback Security On and Off
Callback security must be turned on to enter many callback security commands.
1. Open a data communications program such as HyperTerminal or PhoneTools.
2. In the terminal window, type AT#Sxxxxxxxx, where xxxxxxxx is your password. Press ENTER. The modem
responds with OK if the setup password is correct and ERROR if it is wrong.
3. Type one of the following commands:
•
•
•
To turn off callback security: Type AT#CBS0 and press ENTER. Callers no longer need a password to
connect to the modem, the modem is unable to call them back, and the stored dialing command locations
0–3 become available.
To turn on both local and remote callback security: Type AT#CBS1. Press ENTER. With local security
turned on, you must enter the setup password before you can enter any AT command except the AT, ATIn,
and AT#Sxxxxxxxx commands. For a description of remote callback security, see the following paragraph.
To turn on remote callback security only: Type AT#CBS2 and press ENTER. With remote callback
security turned on, each caller is asked to enter a password, is called back, and then is asked to enter the
password again before a connection can be made. Also, dialing command locations 0–3 for use with the
DS=y dialing command are replaced by callback dialing command locations 0–29.
•
To temporarily disable callback security if the modem is set to #CBS1 or #CBS2 (for instance, to call
another modem): Type AT#CBS3 and press ENTER. The modem returns to its original setting when you
issue the hangup command (+++ATH) or the modem is reset. Note that if a remote modem breaks the
connection, callback security remains disabled.

Chapter 6 – Callback Security
Setting Callback Security Message Parity
The modem’s parity must match the parity of the computer to which the modem is connected.
1. Open a data communications program such as HyperTerminal or PhoneTools.
2. In the terminal window, type AT#Sxxxxxxxx, where xxxxxxxx is your password. Press ENTER. The modem
responds with OK if the setup password is correct and ERROR if it is wrong.
3. The modem’s parity default value is No parity (AT#CBP0). To change the modem’s default to use even parity,
type AT#CBP2. Press ENTER. For odd parity, type AT#CBP1. Press ENTER.
4. To store the new parity value, type AT&W. Press ENTER.
Assigning Callback Passwords and Phone
Numbers
1. Open a data communications program such as HyperTerminal or PhoneTools.
2. In the terminal window, type AT#Sxxxxxxxx, where xxxxxxxx is your password. Press ENTER. The modem
responds with OK if the setup password is correct and ERROR if it is wrong.
3. Enable callback security by typing AT#CBS1 or AT#CBS2 and pressing ENTER.
4. To store a callback password for the first callback memory location, type AT#CBN0=xxxxxxxx, where xxxxxxxx
is the first password. Press ENTER. The password must be unique, must be six to eight characters in length, and
must not contain a + or - character. The callback password is case sensitive.
5. To store a callback password for the second callback memory location, type AT#CBN1=xxxxxxxx, where
xxxxxxxx is the second password. Press ENTER. Note that the memory location number in the command is
incremented by one.
6. Repeat as many times as necessary, up to memory location 29, until all passwords are entered.
7. To store a callback phone number in the first memory location, type AT&Z0=[+][-]AT(DT or DP)xxxxxxxx[,???],
where xxxxxxxx is the dialing string. Press ENTER. The phone number must be preceded by DT for tone dialing
or DP for pulse dialing. The dialing string can also include other AT commands.
Example: AT&Z0=+-ATM0DT5551212. Up to 35 characters can be used. The +, -, and ??? characters are
optional:
+ Number entry. Enables a mobile caller to enter his current phone number for callback.
-
Direct connection. Enables a caller to choose direct connection without being called back.
,??? Extension entry. Must be used with the + command. Enables a caller to enter an extension number for
callback. The number of ? characters must equal the number of digits in the extension.
8. To store a callback phone number in the second memory location, type AT&Z1=[+][-]AT(Dt or
DP)xxxxxxxx[,???], where xxxxxxxx is the dialing string, and press ENTER. Note that the memory location
number in the command is incremented by one.
9. Repeat, through memory location 29, until all dialing strings are entered.
10. To review your entries, type AT&V and press ENTER.
Note: A form is provided on the last page of this chapter to help you plan or keep track of password and phone
number assignments.

Chapter 7 – Troubleshooting
Chapter 7 – Troubleshooting
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 cannot connect when dialing.
The modem disconnects while online.
The modem cannot connect when answering.
File transfer is slower than it should be.
Data is being lost.
There are garbage characters on the monitor.
The modem doesn’t work with Caller ID.
Fax and data software can’t run at the same time.
If you experience problems, please check the following possibilities before calling Technical Support (see Appendix F).
None of the Indicators Light
When you turn on the modem, the LED indicators on the front panel should flash briefly as the modem runs a self-test. If
the LEDs remain off, the modem is probably not receiving power.
•
Make sure the modem’s power switch is on, especially if you normally turn the modem on by turning on a power
strip.
•
•
If the modem is plugged into a power strip, make sure the power strip is plugged in and its power switch is on.
Make sure the power supply is firmly connected to the modem and the power supply’s power cord is firmly
connected to both to the power supply and the wall outlet or power strip.
•
If the power strip is on and the modem switch is on, try moving the power supply to another outlet on the power
strip.
•
•
Test that the outlet is live by plugging another device, such as a lamp, into it.
The modem or power supply may be defective. If you have another Multi-Tech modem, try swapping modems. If
the problem goes away, the first modem or power supply might be defective. Call Technical Support for
assistance.
CAUTION: Do not under any circumstances replace the power supply with one designed for another product; doing so
can damage the modem and void your warranty.
The Modem Does Not Respond to Commands
•
•
Make sure the modem is plugged in and turned on. (See “None of the Indicators Light.”)
Make sure you are issuing the modem commands from data communication 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 communication program, the TR LED should be lit, then type
AT and press ENTER. If you get an OK response from your modem, your connections are good and the problem
likely is in the connection setup in your communication software.
Try resetting your modem by turning it off and on. If you are using DOS or Windows 3.1 communication
software, make sure the initialization string includes &F as the first command, to cancel any “leftover’ command
that could affect the modem’s operation.
If you don’t get an OK, the problem may still be in the communication software. Make sure you have done
whatever is necessary in your software to make a port connection. Not all communication programs connect to
the COM port automatically. Some connect when the software loads and remain connected until the program
terminates. Others can disconnect without exiting the program. The modem’s TR indicator lights to show that
the software has taken control of the modem through the COM port.

•
•
Your communication software settings may not match the physical port to which the modem is connected. The
serial cable might be plugged into the wrong connector—check your computer documentation to make sure. Or
you might have selected a COM port in your software other than the one the modem is physically connected
to—compare the settings in your software to the physical connection.
If the modem is on, the cable is plugged into the correct port, the communication software is configured
correctly, and you still don’t get an OK, the fault might be in the serial cable. Make sure it is firmly connected at
both ends.
•
•
Is this the first time you have used the cable? If so, it may not be wired correctly. Check the cable description on
the packaging to make sure the cable is the right one for your computer.
Peripheral expansion cards, such as sound and game cards, might include a serial port preconfigured as COM1
or COM2. The extra serial port, or the card itself, may use the same COM port, memory address, or interrupt
request (IRQ) as your communication port. Be sure to disable any unused ports.
Windows 9x: Right-click on My Computer, select Properties from the menu, click on the Device Manager tab,
double-click on Ports, then double-click on the communication port your modem is connected to. In the port’s
Properties sheet, click on the Resources tab to see the port’s input/output range and interrupt request. If
another device is using the same address range or IRQ, it appears in the Conflicting Device List. Uncheck
Use automatic settings to change the port’s settings so they do not conflict with the other device, or select the
port the conflicting device is on and change it instead. If you need to open your computer to change switches or
jumpers on the conflicting device, refer to the device’s documentation.
Windows NT 4.0: To look for address or IRQ conflicts, click Start, Programs, Administrative Tools (Common),
and Windows NT Diagnostics. In the Windows NT Diagnostics dialog box, click the Resources tab to see
which input/output ranges and interrupt requests are in use. If you need to open your computer to change
switches or jumpers on the conflicting device, refer to the device’s documentation.
•
•
The serial port might be defective. If you have another serial port, install the modem on it, change the COM port
setting in your software, and try again.
The modem might have a problem beyond the scope of this user guide. If you have another Multi-Tech modem,
try the other modem (if there is no problem with the other modem, call Technical Support for assistance. See
Appendix F for phone numbers).
The Modem Cannot Connect When Dialing
There can be several reasons the modem fails to make a connection. Possibilities include
•
•
•
•
•
•
•
•
lack of a physical connection to the telephone line.
a wrong dial tone.
a busy signal.
a wrong number.
no modem at the other end.
a faulty modem, computer, or software at the other end.
incompatibility between modems
poor line conditions.
You can narrow the list of possibilities by using extended result codes. Extended result codes are enabled by default. If
they have been disabled, include V1X4 in the modem’s initialization string, or in terminal mode enter ATV1X4 and press
ENTER. When you dial again, the modem reports the call’s progress.
•
If the modem reports NO DIALTONE, check that the modem’s telephone line cable is connected to both the
modem’s LINE jack (not the PHONE jack) and the telephone wall jack. If the cable looks secure, try replacing it.
If that doesn’t work, the problem might be in your building’s telephone installation. To test the building
installation, plug a telephone into your modem’s telephone wall jack and listen for a dial tone. If you hear a dial
tone, your modem might be installed behind a corporate 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 can’t, change
your modem’s initialization string to replace X4 with X3, which will cause the modem to ignore dial tones.
•
If the modem reports BUSY, the other number might be busy, in which case you should try again later.
However, it might indicate that you have failed to add a 9, the 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 modem’s
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 HyperTerminal, select Connect from the Call menu, click Dialing
Properties, and type 9 in the local and long distance boxes in How I dial from this location.

Chapter 7 – Troubleshooting
•
•
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.
•
Poor line conditions can affect the connection. When using V.34 or V.32 client-to-client connections in poor
conditions, setting S38=0 may result in better performance.
The Modem Disconnects While Online
•
If you are not using Modem on Hold, Call Waiting can interrupt your connection when someone tries to call you.
If you have Call Waiting service, disable it before each call. In most telephone areas in North America, you can
disable Call Waiting by preceding the telephone number with *70 (but first check with your local telephone
company).
You can automatically disable Call Waiting by including the disabling code in the modem’s 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 HyperTerminal, select Connect 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, the telephone jack, and AC power.
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.
•
Your ISP 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.
Modem Cannot Connect When Answering
•
The default DTR Control command (&D2) inhibits autoanswer. To enable autoanswer, change DTR Control to
&D0, and make sure &Q0, &Q5, or &Q6 is also set. For more information, see the &D command in the AT
Commands Reference Guide. For information on changing the modem’s default configuration, see “Install and
Configure Your Software” in Chapter 2.
•
•
Autoanswer might be disabled. Turn on autoanswer in your communications program or send the command
ATS0=1 (ATS0=2 if you have Caller ID service) to your modem in terminal mode.
Telephone line is not functional or is connected to PHONE jack and should be connected to the LINE jack.
File Transfer Is Slower Than It Should Be
•
•
If you are using a slow transfer protocol, such as Xmodem, try Zmodem or Ymodem/G instead.
Is your line noisy? If there is static on your line, the modem has to resend many blocks of data to ensure
accuracy. You must have a clean line for maximum speed.
•
•
Are you downloading a compressed file with MNP 5 hardware compression enabled? Since hardware data
compression cannot compress a file already compressed by an archiving program, the transfer can be
marginally slower with data compression enabled than with it disabled.
Does your Internet service provider (ISP) use the same 56K protocol as your modem? The default setting of
your modem is to connect using either the V.92 or the V.90 protocol, depending on which one the ISP’s modem
is using. If your ISP uses the V.90 protocol, the maximum speed you will be able to upload at is 33,600 bps.
Check with your ISP to see which protocols it supports.
•
•
Are you trying to send a file to another client modem? If so, then your maximum possible connect speed is
33,600 bps. You can upload at speeds up to 48,000 bps only when connected to an ISP that supports the V.92
protocol.
Try entering the I11 command or the &V command in command mode to display information about the last
connection, making a screen print of the connection statistics, and checking for parameters that might be
unacceptable.

Chapter 7 – Troubleshooting
Data Is Being Lost
•
If you are using data compression and a high speed serial port, set the serial port baud rate to two to six times
the data rate.
•
•
Make sure the flow control method you selected in software matches the method selected in the modem.
Try entering the I11 command or the &V command in command mode to display information about the last
connection, making a screen print of the connection statistics, and checking for parameters that might be
unacceptable.
There Are Garbage Characters on the Monitor
•
•
•
Your computer and the remote computer might be set to different word lengths, stop bits, or parities. If you have
connected at 8-N-1, try changing to 7-E-1, or vice-versa, using your communication software.
You might be experiencing line noise. Enable error correction, if it is disabled, or hang up and call again; you
might get a better connection the second time.
At speeds above 2400 bps, the remote modem might not use the same transmission or error correction
standards as your modem. Try connecting at a slower speed or disabling error correction. (With no error
correction, however, line noise can cause garbage characters.)
•
Try entering the I11 command or the &V command in command mode to display information about the last
connection, making a screen print of the connection statistics, and checking for parameters that might be
unacceptable.
The Modem Doesn’t 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.
NOTE: The modem supports US Bellcore standard caller ID only.
Fax and Data Software Can’t Run at the Same
Time
•
Communication devices can be accessed by only one application at a time. In Windows 2000 and higher, you
can have data and fax communication applications open at the same time, but they cannot use the same
modem at the same time.

Appendix B – Upgrading the Modem’s Firmware
Appendix B – Upgrading the
Modem’s Firmware
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.
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 (you can view this on 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 and the appropriate Flash Wizard for your modem.
4. Install the Flash Wizard and extract the firmware .HEX file from the file you downloaded.
5. Document and clear your stored parameters.
6. Upgrade the modem’s firmware using the .HEX file and the Flash Wizard.
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. If you are using Windows 95 or above, you can use Windows
HyperTerminal.
2. In the program’s 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 ATI, press ENTER, and record your results. The model number and firmware version should
appear similar to that shown below.
LT V.92 1.0 MT5634ZBA-V-V92 Serial Voice/Data/Fax Modem Version 1.25k
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.
ZBA/firmware.asp.
2. Scroll down to your modem model number.
3. Look at the firmware version number for your modem.
4. If the firmware version number matches the firmware version number found in “Step 1: Identify the
Modem Firmware,” you have the current firmware version and do not need to be update.
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.

Appendix B – Upgrading the Modem’s Firmware
Step 3: Download the Upgrade File
1. If you are not already at the MultiModem ZBA 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, click the Flash Wizard utility for your operating system to download
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\.
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&W1Z command to the modem to clear the stored parameters.
1. Run your favorite terminal program. If you are using Windows 95 or above, you can use Windows
HyperTerminal.
2. In the program’s terminal window, type AT&V and press ENTER to list your modem’s current parameters.
3. Record your parameters by saving the screens and sending them to your printer.
4. Type AT&W1Z and press ENTER to clear your stored parameters and reset your modem to factory
default.
5. Close the terminal program.
Step 6: Upgrade the Modem’s 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 (example: ARQG125A.HEX).
WARNING: Never install an older version of firmware over a newer version. Doing this 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 modem is turned 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.
5. When the flash upgrade is complete, the message Programming Complete appears. Click Next to
continue.
6. 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 ATI in the terminal window and pressing ENTER.

Appendix E – Installing a Modem under Linux
Appendix E – Installing a Modem
under Linux
This appendix explains how to install a modem on a computer operating under the Red Hat Linux 6.2 operating system.
Other versions of Red Hat and other Linux operating systems should be similar. Briefly, in Linux, you do not need drivers
for most standard external modems and most internal ISA bus modems. Programs in Linux commonly call upon the port,
rather than the modem.

Appendix F – Connecting to a Cisco Router
Appendix F – Connecting to a
Cisco Router
Connecting to a Cisco Router Console Port
The console port on the Cisco IOS® router is an asynchronous serial port configured as data communications equipment
(DCE). For Cisco 1000, 1600, 2500, 2600, and 3600 series routers, the console port uses an RJ-45 connector.
WARNING: Do not connect the modem to the Cisco router’s auxiliary port. This procedure and document apply only to
the Cisco router’s console port.
Step 1: Configure the Modem for your Country or Region
Configure the modem defaults to match the requirements of the country/region in which it will be used. For
information on how to do this, see “Step 5: Configure the Modem for your Country or Region” in Chapter 2.
Step 2: Configure for Callback Security in Direct Connect Mode
Callback security requires a caller to give a correct password before sending data to the system. If you do not plan to
use this feature, skip to Step 3. Note: Setting the modem for callback security in direct connect mode disables the
remote configuration feature of the modem.
To Turn Direct Connect Callback Security On and Off
Callback security must be turned on to enter many callback security commands.
Using a terminal program such as HyperTerminal, type the command AT#Sxxxxxxxx, where xxxxxxxx is
your password (1 to 8 characters long). Press ENTER. The modem responds with OK if the setup
password is correct and ERROR if it is wrong. The default password is MTSMODEM. If you wish to
change the password, then type the command AT#S=xxxxxxxx, where xxxxxxxx is the new password (1
to 8 characters long), and press ENTER.
Type one of the following commands:
•
•
To turn on remote callback security only, type AT#CBS2 and press ENTER.
To turn on both local and remote callback security, type AT#CBS1 and press ENTER. When local
security is turned on, you must enter the setup password before you can enter any AT command from
a local terminal except the AT, ATIn, and AT#Sxxxxxxxx commands.
Type AT&W0 to store the above commands to nonvolatile memory.
To Set the Parity of the Callback Security Messages
The modem’s password prompt and messages parity must match the parity of the computer to which the
modem is connected.
1. The default parity setting for your modem is no parity (AT#CBP0). To change the modem’s prompt
messages to use even parity, type AT#CBP2 and press ENTER. For odd parity, type AT#CBP1 and press
ENTER.
2. To store the new parity value, type AT&W and press ENTER.
To Assign Callback Passwords
To store a callback password for the first callback memory location, type AT#CBN0=xxxxxxxx, where
xxxxxxxx is the first password. Press ENTER. The password must be unique, must be 6 to 10 characters
in length, and must not contain a + or - character.
To store a callback password for the second callback memory location, type AT#CBN1=xxxxxxxx, where
xxxxxxxx is the second password, and press ENTER. Note that the memory location number in the
command is incremented by one.
Repeat as many times as necessary until all passwords have been entered.
To review your entries, type AT&V and press ENTER.
To set the modem for direct connect mode, type AT%H1 and press ENTER.
To Call a Modem Configured for Callback Security
1. Using a terminal program and an originating modem, dial the number of the modem connected to the
Cisco router, which we will call the “remote modem.”
2. When connection is established, the remote modem responds: Password>
3. Type a direct connection password, and press ENTER. You have three attempts or one minute to enter a
valid password.
4. If the password is valid, the message OK Connecting appears and the modems establish a working
connection.

Appendix F – Connecting to a Cisco Router
Step 3: Console Port Final Setup
Send the following command string to the modem connected to the console port of the Cisco router:
AT%R1&W0
The %R1 command sets E0, Q1, &D0, &K0, $SB9600, and %S1, and the &W0 command stores the commands to
memory. The %R1 command sets the following functions:
E0
Turns command echo off
Q1
Turns result codes off
&D0
&K0
$SB9600
%S1
Ignores DTR from the DTE
Selects no flow control
Sets the serial baud rate to 9600 bps.
Disables command mode at all serial speeds except 115200 bps.
The modem is now configured for use on the Cisco router console port. Note that command echo and result codes
have been turned off. If it becomes necessary to send additional AT commands to the modem after it has been so
configured, there will be little feedback from the modem that it has received and acted upon the command. Only
commands such as ATI0 that request specific data from the modem will send any data to the DTE as an indication
that the modem has accepted the command. Temporarily turning on command echo and result codes might ease
reconfiguration of the modem. When the modem is connected to the console port, turn the modem off and then on
again. This will set the serial baud rate to 9600 bps as the $SB9600 command is implemented.

To connect a personal computer to the console port, use the RJ-45-to-RJ-45 roll-over cable and either the RJ-45-to-DB-
25 female DTE adapter or the RJ-45-to-DB-9 female DTE adapter (labeled “TERMINAL”).

Remote Configuration
The configuration of the modem described in Step 3 contains the core settings that allow the modem to function properly
on the console port of the Cisco router. Commands in this section may be done remotely by calling into the MT5634ZBA
attached to the console port with another modem.
Note: Setting country/region configuration and turning on callback security cannot be done remotely. Nor can all
commands be executed remotely if the remote modem is set for callback security; remote configuration of a modem so
configured is not recommended.
Establish a data connection with a remote MT5634ZBA modem.
Send three remote configuration escape characters followed by AT and the setup password, and then press ENTER.
Example: %%%ATMTSMODEM. You have four tries to enter the correct password before being disconnected.
If the password is correct, the remote modem may respond with OK. Note: If the modem has previously been
configured with command echo off and result codes off, it may be difficult to determine if the remote modem is
responding to commands. The ATI command can be used for this purpose. Even with echo and result codes off,
the modem will respond with the requested ID string if it is properly receiving the command.
You can now send AT commands to configure the remote modem.
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.
Note: This step is important to ensure that the connection is broken cleanly.
